Iridium NEXT is a commercial constellation of 66 communication satellites operated by ICI (Iridium Communications Inc.) which provides the only complete global satellite communications coverage service - Iridium Certus. The satellites have been launched in eight stages, starting in January 2017 and finishing in January 2019, and have successfully replaced the previous generation Iridium satellites.
|Launch date||14 January 2017|
|End of life date||January 2037|
|CEOS EO Handbook||See Iridium NEXT summary|
Each Iridium NEXT satellite contains a radio array antenna for communication that transmits to users via L-band frequency which can easily penetrate clouds, forest canopies and other similar entities that can obscure the signal. Relay communications occur between satellites via Ka-band crosslinks, with each satellite able to communicate with four surrounding satellites to efficiently transmit data.
ICI offered to host payloads for government and scientific organisations onboard and as such, each satellite hosts two payloads. Aireon’s Global ADS-B (Automatic Dependent Surveillance-Broadcast) receiver maintains global, real-time aircraft surveillance. Aircraft ID, position, altitude, course, and speed are transmitted to air traffic control. Using this implementation Aireon has established Aireon ALERT (Aircraft Locating and Emergency Response Tracking), the only free, global, real-time emergency aircraft location service. The second payload is the global AIS (Automatic Identification System) operated by Harris Corporation and exactEarth. AIS communicates a ship's ID, position, course, and speed to local ships and stations ashore. This information is used to monitor the local area, and prevent collisions. Having been implemented aboard Iridium NEXT, for the first time AIS offers global coverage.
ADS-B can monitor over 10,000 aircraft with an update rate of eight seconds and latency of 1.5 seconds. AIS has a latency of less than one minute.
The 66 Iridium NEXT satellites orbit across six planes that intersect at the poles with 11 satellites evenly spread across each plane. Each satellite undertakes a polar orbit with an inclination of 86.4° at an altitude of 780 km. The orbit has a period of 101 minutes.
Space & Hardware Components
All Iridium NEXT satellites were launched on SpaceX Falcon-9 rockets as part of the largest commercial launch deal ever to be made with SpaceX. The launch began the process of replacing the existing Iridium constellation. This complex task of replacing satellites one by one is known as a ‘slot swap’.
Iridium NEXT (Hosting Payloads on a Communications Constellation)
In 2007, Iridium Satellite LLC announced its plans to develop its Iridium NEXT constellation and start deployment in the timeframe 2015-2017. With the announcement came the offer of hosted payloads for government and scientific organizations. Iridium NEXT, in continuity to the current Iridium system of 66 satellites, will provide 24/7 real-time visibility over the entire Earth’s surface and its atmosphere. ICI (Iridium Communications Inc.) is the only MSS (Mobile Satellite Service) company offering global voice and data coverage. ICI owns and operates the constellation and sells equipment and access to its services. Satellites communicate with neighboring satellites via Ka-band ISLs (Inter-Satellite Links). Each satellite can have four ISLs: two to neighbors fore and aft in the same orbital plane, and two to satellites in neighboring planes to either side.
Hosted payloads on Iridium NEXT will provide an unmatched opportunity to meet Earth observation and government mission requirements in the near term at a fraction of the cost of designing, building, launching and maintaining dedicated platforms in space.
The Iridium NEXT system is expected to maintain Iridium’s current unique architecture that provides truly global coverage, with expanded capacity, higher data speeds, new services, flexible payload architecture capable of supporting future product enhancements, cost effectiveness in maintaining and operating the network, and a design to host secondary payloads.
Major parameters of the mission are given in Table 1. Each Iridium NEXT satellite has an allocation of 50 kg in mass, 30 cm x 40 cm x 70 cm in volume, 50 W of average power, and 100 kbit/s average data rate for each hosted payload.

Background: Iridium is a MSS (Mobile Satellite Services) provider - the only network provider offering 100% worldwide coverage. The network is a very unique, resilient LEO (Low-Earth Orbiting) satellite constellation of 66 satellites plus in-orbit spares. The original Iridium constellation of 66 satellites plus 6 spares was launched between May 5, 1997 and May 17, 1998.
A comprehensive plan to replenish the Iridium constellation, known as Iridium NEXT will launch 66 new satellites to replace the current constellation, with launches expected to begin in 2015. Also planned are 6 in-orbit spare satellites and 9 ground spares. Iridium NEXT features increased subscriber capacity, higher data speeds, and capacity for hosting payloads.
Data handling for hosted payloads: Although the satellites in the Iridium system are primarily designed to support the Iridium communications mission, they have been adapted to accommodate hosted payload missions. Mission data and sensor telemetry and command data for these missions can be transported in near real-time utilizing the K-band network of crosslinks between satellites, feeder links to the ground, and teleports connecting the satellites through earth stations to a MPLS (Multiprotocol Label Switching) cloud called the Teleport Network.
Iridium operations manage deployment and operation of the Iridium system. Iridium NEXT would retain the capability to turn off the hosted payload, in an extreme emergency situation, to preserve the health of the Iridium satellite. Iridium enables a hosted payload command and data path to an MPLS cloud. A customer designated sensor operations facility would manage the hosted payloads in-orbit on the Iridium NEXT satellite using the command and data path provided by Iridium operations. These functions include:
- Sensor operations tables
- Updating software or firmware
- Data stream management (pull or push from the MPLS cloud)
- Anomaly resolution.
This Hosted Payload Operations Center will provide the data processing capability for the sensor data. It will receive the data stream from the MPLS cloud and processes the data for end users. End users can provide feedback to sensor operations and data processing.
Benefits: The hosted payloads offer a customer the following value proposition:
• Unprecedented geospatial and temporal coverage : 66 interconnected satellites with coverage over the entire globe
• Low latency : Real-time relay of data to and from payloads in space
• User control : Data collection and hosted payload access seamlessly through Iridium infrastructure or private gateways
• Cost effective : Access to space at a fraction of the cost of a dedicated mission
• Exclusive : No other opportunity like this is likely to become available in the coming decades.
• Consistent with 2010 U.S. President’s National Space Policy : Commercial capabilities, cost effective access.
Iridium Next SensorPod: A SensorPOD is a virtual container (enclosure) that is a designated subset of the total Iridium NEXT hosted payload volume and is applicable for small payloads and payload suites that only require a small portion of the available volume (Figure 1).
SensorPod “containers” can be arranged in varying configurations (i.e., stacked like blocks) to support many different customer experiments. SensorPod geometries can also be scaled on a case-by-case basis to accommodate specific customer payload needs. SensorPods are designed to be located and oriented in the hosted payload volume to provide both nadir and/or RAM FOV (Field-of-View) options. An example of a notional configuration which includes a combination of a “primary” nadir-viewing SP and multiple “secondary” SensorPods is shown in Figure 2.
Customers may fill each SensorPod volume with one or several payloads as long as they remain within the overall sensor volume, mass, power and communication allocations. Customer payloads are provided with mechanical and thermal interface routing plates and conditioned electrical power and communications via a hub through external harnesses.
In June 2010, TAS (Tales Alenia Space) of France was awarded a contract from ICI (Iridium Communications Inc.) for the design and construction of 81 satellites — 66 operational satellites, six in-orbit spares, and an additional nine ground spares. In turn, TAS has selected Orbital ATK [former OSC (Orbital Sciences Corporation] as a subcontractor for the integration of Iridium NEXT satellites and the hosted payloads in a facility located in Gilbert, AZ. 9) 10) 11) 12) 13) 14) 15) 16)
Iridium has also signed the largest single commercial launch deal ever with Space-X (Space Exploration Technologies Corp.) to be the primary launch services provider for Iridium NEXT.
In addition, Iridium entered into two comprehensive, long-term agreements with The Boeing Company for maintenance, operations, and support of Iridium’s satellite network. Under the first agreement, Boeing will continue operating Iridium’s current satellite constellation and will provide support for Iridium’s satellite control system. The second agreement is a new support services contract under which Boeing will become the exclusive operations and maintenance provider for Iridium NEXT. The combination of these agreements allows Iridium to benefit from having a single operator during the transition from the current constellation to Iridium NEXT.

The first 10 Iridium NEXT satellites were launched on January 14, 2017 (17:54:39 UTC) on a Falcon-9 vehicle of SpaceX from VAFB, CA. Confirmation of a successful deployment of all 10 Iridium NEXT satellites came at about T plus 1 hour and 17 minutes after liftoff from Vandenberg. — In parallel, the first stage of the launch vehicle was recovered at sea off the coast of California. It was the seventh time SpaceX was able to land its first stage on an uncrewed ship. 27) 28)
• This is the first in a series of seven Iridium NEXT launches, which are scheduled over the next 15 months with SpaceX. Each launch will include a payload of ten Iridium NEXT satellites – the heaviest payload yet to fly on a Falcon 9 – and begin a one-for-one satellite replacement of Iridium’s existing global satellite constellation, the largest commercial satellite constellation in space. This process is known as a “slot swap”, and one of this scale has never been attempted before. Due to the size and complexity of this endeavor, Iridium NEXT has been referred to as one of the largest “tech refreshes” in history.
• “Today Iridium launches a new era in the history of our company and a new era in space as we start to deliver the next-generation of satellite communications,” said Matt Desch, chief executive officer of Iridium. “We have been working endless hours for the last eight years to get to this day, and to finally be here with ten Iridium NEXT satellites successfully deployed into low-Earth orbit is a fulfilling moment. We are incredibly thankful for all of the hard work from our team, as well as our partners, to help us achieve this milestone.”
• In addition to partnering with SpaceX for the launch of 70 Iridium NEXT satellites, the manufacturing, assembly and testing of all 81 satellites is being conducted by Thales Alenia Space and their subcontractor for production, Orbital ATK. Both partners have played integral roles in the Iridium NEXT program, including the management of an 18-station, state-of-the art assembly line production system, making today a possibility.
• The hosted payloads onboard the Iridium NEXT satellites are manufactured by Harris Corporation and will include a payload from Iridium’s partner Aireon, which will for the first time provide a real-time global aircraft tracking and surveillance service for air traffic controllers and airlines, extending aircraft visibility across the planet.
• The next major milestone will be the validation that all ten satellites are receiving telemetry from our SNOC (Satellite Network Operations Center) in Leesburg, VA, and the completion of on-orbit testing of these satellites, to validate performance requirements are met. The second Iridium NEXT launch will be scheduled after this testing is completed, in April. The entire Iridium NEXT network is scheduled to be completed in 2018.
• The original Iridium constellation was launched during the 1990s and early 2000s. It provides voice and data coverage for some 800,000 subscribers through 66 active satellites.
The comeback mission kicks off a busy launch manifest with more than 20 SpaceX rocket flights expected this year as the company prepares to start launching astronauts, vital national security payloads and a slate of valuable telecommunications satellites for global broadcasters and network clients.
• January 6, 2017: The FAA (Federal Aviation Administration) today “accepted the investigation report” regarding the results of SpaceX’s investigation into the cause of the company’s catastrophic Sept. 1, 2016 launch pad explosion of a Falcon 9 rocket in Florida, and simultaneously “granted a license” for the ‘Return to Flight’ blastoff of the private rocket from California as soon as next week. 31)
- With today’s definitive action from the FAA the path is now clear for SpaceX to resume launches of the Falcon 9 rocket as soon as Monday, Jan. 9, 2017.
• January 2, 2017: Over the past four months, officials at the Federal Aviation Administration (FAA), the US Air Force (USAF), the National Aeronautics and Space Administration (NASA), the National Transportation Safety Board (NTSB), along with several industry experts, have collaborated with SpaceX on a rigorous investigation to determine the cause of the anomaly that occurred September 1 at SLC-40 (Space Launch Complex 40) at Cape Canaveral Air Force Station in Florida. 29) 30)
- This investigation team was established according to SpaceX's accident investigation plan, as approved by the FAA. As the primary federal licensing body, the FAA provided oversight and coordination for the investigation. Investigators scoured more than 3,000 channels of video and telemetry data covering a very brief timeline of events—there were just 93 milliseconds from the first sign of anomalous data to the loss of the second stage, followed by loss of the vehicle. Because the failure occurred on the ground, investigators were also able to review umbilical data, ground-based video, and physical debris. To validate investigation analysis and findings, SpaceX conducted a wide range of tests at its facilities in Hawthorne, California, and McGregor, Texas.
- The accident investigation team worked systematically through an extensive fault tree analysis and concluded that one of the three COPVs (Composite, Over-wrapped Pressure Vessels) inside the second stage LOX (Liquid Oxygen) tank failed. Specifically, the investigation team concluded the failure was likely due to the accumulation of oxygen between the COPV liner and over-wrap in a void or a buckle in the liner, leading to ignition and the subsequent failure of the COPV.
- Each stage of Falcon 9 uses COPVs to store cold helium, which is used to maintain tank pressure, and each COPV consists of an aluminum inner liner with a carbon over-wrap. The recovered COPVs showed buckles in their liners. Although buckles were not shown to burst a COPV on their own, investigators concluded that super chilled LOX can pool in these buckles under the over-wrap. When pressurized, oxygen pooled in this buckle can become trapped; in turn, breaking fibers or friction can ignite the oxygen in the over-wrap, causing the COPV to fail. In addition, investigators determined that the loading temperature of the helium was cold enough to create SOX (Solid Oxygen), which exacerbates the possibility of oxygen becoming trapped as well as the likelihood of friction ignition.
- The investigation team identified several credible causes for the COPV failure, all of which involve accumulation of super chilled LOX or SOX in buckles under the over-wrap. The corrective actions address all credible causes and focus on changes which avoid the conditions that led to these credible causes. In the short term, this entails changing the COPV configuration to allow warmer temperature helium to be loaded, as well as returning helium loading operations to a prior flight proven configuration based on operations used in over 700 successful COPV loads. In the long term, SpaceX will implement design changes to the COPVs to prevent buckles altogether, which will allow for faster loading operations.
- SpaceX is targeting return to flight from Vandenberg's Space Launch Complex 4E (SLC-4E) with the Iridium NEXT launch on January 8, 2017.
• In June 2010, SpaceX was awarded a contract by Iridium Communications to launch 70 Iridium NEXT satellites aboard the Falcon 9 launch vehicle, between 2015 and 2017. 32)
• Note: This launch is contingent upon the FAA’s approval of SpaceX’s return to flight following the anomaly that occurred on September 1, 2016, at Cape Canaveral Air Force Station, Florida. The investigation has been conducted with FAA oversight. Iridium expects to be SpaceX’s first return to flight launch customer. 33)
• However, the first two Iridium Next satellites were set to launch on a Dnepr rocket of ISC Kosmotras, a Moscow-based company with joint Russian-Ukrainian ownership (Ref. 19).
- In June 2011, Iridium Communications signed a contract with ISC (International Space Company) Kosmotras as a supplemental provider of launch services for its next-generation satellite constellation, Iridium NEXT. The contract enables ISC Kosmotras to provide Dnepr launch services for the Iridium NEXT program in 2015 and beyond. Iridium has the capability and flexibility to launch the Iridium NEXT satellites on Kosmotras Dnepr and SpaceX Falcon 9 rockets to successfully deploy the Iridium NEXT constellation. 34)
- Note: Iridium Communications has pushed back the inaugural launch of its second-generation constellation to October 2015, saying payload-software issues need more time to validate. Iridium Communications said the delay will have no effect on the in-service date for the 66-satellite Iridium Next constellation. 35)
Orbit: Circular polar orbit, altitude = 780 km, inclination = 86.4°, period = 101 minutes (the spacecraft of the constellation will be positioned in 6 orbital planes).
However, the first ten Iridium NEXT satellites were delivered to a 625 km temporary parking orbit where they will be tested and exercised by Iridium over the coming weeks. Upon meeting testing and validation requirements, the satellites will then be moved into their 780 km operational orbit and begin providing service to Iridium’s customers.
The 66-satellite main constellation (+6 in-orbit spares), configured in 6 orbital planes with 11 evenly spaced slots per plane, provides continuous global coverage as demonstrated by the RF footprints in Figure 6. This is achieved though cross-linked satellites operating as a fully meshed network that is supported by multiple in-orbit spares to provide real-time data downlink to the Iridium operated ground station network. The constellation has a design lifetime greater than 10 years in a polar orbit at 780 km with an inclination of 86.4°.

• May 24, 2021: Iridium Communications Inc. today announced that it has made a strategic investment in DDK Positioning (DDK), an Aberdeen, Scotland based provider of enhanced Global Navigation Satellite System (GNSS) accuracy solutions. 45)
- DDK uses the Iridium® network to provide global precision positioning services that can augment GNSS constellations, including GPS and Galileo, to significantly enhance their accuracy for critical industrial applications. DDK is also developing similar services for other GNSS constellations, such as GLONASS and BeiDou. Terms of the investment are not being disclosed.
- Standard positioning accuracy through a system like GPS is typically within 10 meters; however, by using the Iridium network, DDK's enhanced GPS accuracy service brings incredibly precise positioning of five centimeters or less. This advanced level of accuracy is ideal for autonomous vehicles like UAVs, precision agriculture applications, offshore infrastructure projects such as windfarm construction, automotive applications like driverless cars, as well as a host of construction, mining, surveying and IoT use cases. Historically, there have been limited geostationary satellite provider options for this type of service, but they suffer from line-of-sight blockage issues and coverage limitations in and around Arctic and Antarctic regions.
- Kevin Gaffney, CEO of DDK Positioning, said, "We are delighted to have embarked on this journey with such a strong and well-respected company as Iridium. This partnership is a perfect fit for DDK Positioning, with Iridium's satellite communications network and our GNSS solution, we are in a position to deliver a truly unique service which is robust, resilient and secure." Gaffney continued that, "The investment made by Iridium will also allow us to grow the company even further while expanding our service offering globally."
- According to a report published by the European Union Agency for the Space Program (EUSPA), augmentation services like those offered by DDK will account for $76.5 billion (€65 billion) in global GNSS market revenue by 2029, while the global GNSS downstream market, including services delivered and hardware devices, is estimated to reach $382 billion (€325 billion).
- "We are impressed with the team that DDK has put together and see great potential for this technology and how it takes advantage of the Iridium network," said Iridium CEO, Matt Desch. "DDK's enhanced positioning is a unique capability that adds a high-value solution on top of our existing portfolio of custom network services. Solutions from Iridium and DDK partners that are focused on precision agriculture, autonomous systems, maritime and infrastructure projects can now experience incredibly precise GNSS accuracy from anywhere on the planet."

• February 27, 2020: Iridium Communications Inc. announced today that the Iridium Certus 700 service is commercially available and is providing the fastest L-band speeds in the industry. When first launched in early 2019, Iridium Certus provided L-band upload and download speeds of up to 352 kbit/s. With the upgrade to Iridium Certus 700, provided at no additional cost to Iridium Certus 350 subscribers, top download speeds have now doubled to up to 704 kbit/s. That is more than 270 kbit/s faster than the top download speed of the closest competitive L-band solution, for the same price per kbit as Iridium Certus 350. 46)
- Unique in the satellite industry, Iridium Certus is the only broadband service that provides truly global, weather-resilient coverage for on-the-move internet and high-quality voice access. Delivered through small form factor, cost-effective antennas and terminals currently available from Cobham and Thales, Iridium Certus has seen growing adoption by the maritime and land-mobile/connected vehicle markets.
• January 13, 2020: Iridium Communications Inc. announced that on December 19, 2019 a Letter of Compliance was signed by the International Mobile Satellite Organization (IMSO), stating it has positively verified the operational and technical requirements as requested by the Maritime Safety Committee (MSC) of the International Maritime Organization (IMO) for Iridium to provide GMDSS (Global Maritime Distress and Safety System) service. The Letter of Compliance was formally presented to Iridium CEO Matt Desch by the Director General of IMSO, Captain Moin Ahmed, during a ceremony at Iridium's headquarters on the morning of January 13, 2020. The issuance of the letter formally authorizes Iridium to now provide satellite GMDSS service, bringing truly global coverage and a choice of both network and equipment to this critical emergency service for the first time. 47)
- GMDSS is a safety of life system that helps rescue mariners in emergency situations while at sea. IMSO serves as regulator for the system, which is partially comprised of satellite networks that transmit distress information to rescue coordination centers around the world, in addition to the dissemination of navigational and meteorological data to vessels at sea.
- "This is a historic moment for public safety in the maritime community globally. The addition of new providers, such as Iridium, for GMDSS services can help to create safer seas for all mariners," said Captain Moin Ahmed, Director General of IMSO.
- Captain Ahmed continued, "Since the inception of GMDSS by the IMO in 1999, a new mobile satellite system, the Iridium® network, has now completed a thorough evaluation to become a recognized mobile satellite system in the GMDSS. Recognition of Iridium marks the start of a new era in GMDSS and enhances the integrity and global coverage of safety services for seafarers across the world, including in the polar regions. The evaluation of Iridium took more than four years, and at various stages the Company successfully demonstrated its capability to comply with the requirements for satellite communication services for maritime safety."
- Concluding his remarks, Captain Ahmed stated, "I am pleased to issue Iridium the 'Letter of Compliance' that officially makes the company the second recognized mobile satellite system in the GMDSS. My organization and I take this opportunity to congratulate Iridium management and everyone in the company for their commitment and contribution to the safety of mariners and their passengers at sea. We look forward to continuing to work with Iridium."
- Iridium's GMDSS service is bringing many new capabilities to the maritime industry, including extending this critical service to the growing number of ships in the waters of the Arctic and Antarctica, otherwise known as Sea Area A4. The new Iridium GMDSS terminals will combine the key three GMDSS services - distress alert, distress voice and Maritime Safety Information – all in one truly global compact terminal. These terminals can provide both normal and emergency communications, including Ship Security Alert System (SSAS), Anti-Piracy/Citadel Communications, and Long-Range Identification and Tracking (LRIT). All of this will be provided in a cost-effective way, making the terminals more affordable for all sizes of vessels, including those that are not required to be GMDSS equipped, such as smaller fishing boats and yachts, but want to take advantage of this invaluable service.
- "This is a monumental achievement for Iridium, and one that took years of hard work and dedication. The maritime industry is recognizing that our network possesses the unique ability to make GMDSS an even more robust system and extend its coverage to the entire planet," said Iridium CEO, Matt Desch. "We are dedicated to keep finding innovative new ways to facilitate safer marine travel."
- Iridium formally began the process to become a recognized GMDSS satellite service provider in 2013, with recognition of the Iridium network meeting all criteria required by the IMO's MSC in May of 2018. In April of 2019, Iridium announced the signing of a Public Services Agreement with IMSO, which details the conditions for IMSO to act as regulator and maintain oversight of Iridium's GMDSS services. This was followed by two additional announcements, one unveiling the first ever Iridium GMDSS terminal, and the second announcing the initial seven GMDSS service providers for the Iridium network. Iridium now continues to work with its partners around the world towards rolling out its truly global GMDSS service throughout the first half of 2020.
• September 18, 2019: A MOU (Memorandum of Understanding) was established between Iridium Communications and OneWeb establishing that they will work together toward a combined service offering. This combined service offering would be designed to make it easier for their mutual partners to offer unique bundling and co-marketing opportunities for the Iridium Certus® L-band services and OneWeb’s Ku-band service. The offering would leverage the strengths of their respective LEO (Low Earth Orbit) networks. This is the first time that LEO operators have collaborated to deliver services in L-band and Ku-band. 48)
- The MOU also creates opportunities for companies that manufacture both OneWeb and Iridium Certus™ terminals. Such new options could include Iridium-OneWeb companion packages in addition to providers being able to offer combined equipment or even new dual-constellation terminals.
- While both are LEO constellations, Iridium® and OneWeb services have different capabilities on their respective bands (L-band and Ku-band), which can create a complementary, full-service option for applications such as heads of state communications, critical tactical services, maritime, disaster response and more.
- Matt Desch, CEO of Iridium said that it’s an exciting time for the industry, and they see great potential for this offering. Their services are unique and complementary, and they know that customers are looking for the capabilities of both our low-Earth-orbiting networks.
- Adrian Steckel, CEO of OneWeb added that they believe the new offering can bring many benefits for their distribution partners. By combining the strengths of their services, they can ensure their partners are able to deliver the most innovative, seamless services to their subscribers across many markets, and in all the places that don’t yet have access to the internet.
- Due to the physics associated with L-band and Ku-band spectrum, the two come with different yet complementary attributes. The OneWeb network will deliver very high-speed broadband connectivity that transfers large amounts of data. It is ideal for applications including Inflight WiFi, Government, and Maritime networks that require global reach, high speed and low latency. Iridium’s crosslinked satellite constellation brings seamless truly global connectivity with highly weather resilient L-band user terminals, making it uniquely suited to provide safety services for ships, aircraft, vehicles and deployed personnel, and can be a regulation-required capability. The combined power of these two networks can work together to deliver capacity, resiliency, and high-speed connectivity to customers anywhere in the world.
- With the first six satellites already launched, OneWeb’s system has already demonstrated broadband speeds of 400 Mbit/s and an average latency of 32 milliseconds. OneWeb will begin monthly launches of more than 30 satellites per month starting in December enabling OneWeb to provide partial service in late 2020 and global coverage in 2021. Iridium Certus® is Iridium’s new technology platform launched in January 2019, and offers the flexibility to scale device speeds, sizes and power requirements both up and down based on the needs of the end-user.
• June 4, 2019: Iridium Communications Inc. and partner Lars Thrane, today unveiled the Lars Thrane (LT) 3100S terminal designed to operate on the Iridium network for Global Maritime Distress and Safety System (GMDSS) vessel carriage requirements, with service targeted to launch in January 2020. This is the first terminal designed to provide truly global GMDSS services and is the first to be offered after the International Maritime Organization's decision to recognize Iridium as just the second-ever satellite provider for this critical service. The terminal offers a superior alternative to the decades-long incumbent option and was unveiled at the 2019 Nor-Shipping conference, in Oslo, Norway and is on display at multiple booths, including at NSSLGlobal – stand B05-17 and Telemar Norge Marlink – stand B02-16. 49)
- "The recognition of the Iridium satellite network to provide GMDSS services fundamentally changes the status quo of the maritime industry. We immediately recognized the unique capabilities Iridium offers and wanted to make sure we provided the very first terminal available for Iridium GMDSS," said Peter Thrane, CEO of Lars Thrane. "The Low-Earth orbiting Iridium network with interconnected satellites allows us to offer multiple services throughout all the world's waterways in a single, compact terminal."
• April 22, 2019: Iridium Communications Inc. has been awarded a new contract by the Defense Information Systems Agency (DISA) to continue supporting the U.S. Department of Defense (DoD) Enhanced Mobile Satellite Service (EMSS) gateway. 50)
- The contract, valued at $54 million over 4.5 years, for Gateway Maintenance and Support Service (GMSS), will ensure that this dedicated ground site continues to operate at peak efficiency and in optimal condition for critical U.S. DoD missions.
- Dedicated for use by the U.S. DoD, their Iridium gateway serves as the uplink and downlink point for the DoD’s EMSS communications capabilities through the Iridium® network. This includes the enhanced capabilities made possible by Iridium’s upgraded satellite constellation, which was formally completed and declared fully operational in February of this year.
- The previous iteration of the GMSS contract was awarded in October of 2013 for a five-year term with a six-month extension option. The subscribers operating under the Iridium EMSS program run by DISA have more than doubled over the five-year period between 2013 and 2018 to 113,000, reflecting a 17.25% compounded annual growth rate. This surge in growth has occurred under the current flat-rate contract program that provides unlimited voice and data services to the U.S. warfighter and other government participants.
- Scott Scheimreif, EVP of government programs, Iridium, said this new contract provides the mechanism for Iridium to help ensure the DoD gateway is able to fully support the new capabilities and services needed to meet the emerging requirements of the warfighter. This is another example of the strategic, long-term relationship between Iridium and the U.S. Department of Defense. The company remains committed to the U.S. DoD and the warfighter as new ways for addressing critical requirements leveraging Iridium's unique satellite network are explored.
• February 6, 2019: Iridium Communications Inc. today hailed the completion of its $3 billion satellite constellation upgrade campaign known as Iridium® NEXT, during a press conference held at the National Press Club in Washington, D.C. During the press conference, the company also used the opportunity to introduce a new small-form-factor transceiver known as the Iridium CertusSM 9770, which will enable creation of new consumer and industrial applications that are highly portable and IoT-friendly, optimized for small size and low cost, yet with higher speeds than in the past thanks to the upgraded Iridium satellite network. 51)
- The completion of the Iridium NEXT campaign comes as the final two satellites required to complete the network refresh were activated on February 5th at approximately 2:15 p.m. EST. With a fully operational constellation, featuring 66 new Iridium satellites and no further launches planned, Iridium has concluded its nearly decade-long capital-intensive program that created an upgraded network both in space and on the ground. After spending several hundred million dollars per year to build and deploy the new network, Iridium expects capital costs to decrease to approximately $35 million per year, with revenues continuing to grow as the company expands into newer revenue streams like broadband, IoT and hosted payloads.
- "The completion of the Iridium NEXT program signifies a new chapter in the Iridium story, one that sees us transforming from a big cash spender to a big cash generator," said Iridium CEO Matt Desch. "This is the realization of a long, successful climb, and reaching the peak, it's gratifying to know the future of the company is secure, and we have now financially matured as a satellite operator. Huge thanks are in order to our entire team, particularly our friends at SpaceX and our prime satellite manufacturer Thales Alenia Space and their teams."
- First announced in 2010, the Iridium NEXT campaign featured eight launches with SpaceX. In total, 81 satellites were built by prime contractor Thales Alenia Space, of which 75 were launched, with 66 in the operational constellation and nine serving as on-orbit spares. Thales Alenia Space was responsible for design and integration of the new satellites, including launch and early operations testing in partnership with Iridium's team at the company's Satellite Network Operations Center in Virginia.
- The upgraded Iridium constellation enables never before possible services such as the AireonSM global aircraft tracking and surveillance system and Iridium Certus, the company's new broadband service, which launched commercially in January 2019. The upgraded network is also fully compatible with the original satellite constellation's services, a notable accomplishment given the size and scope of the upgrade.
- Jean-Loic Galle, CEO of Thales Alenia Space remarked: "The 75 in-orbit satellites are working very well, and the overall end-to-end performance improvement for existing customers is dramatic. Two years after the first launch, Iridium NEXT, one of the most sophisticated communication systems in the world, is now totally deployed and fully operational. All the satellites are interconnected, and we have ensured a continuity of service without any interruption. We did it! And we did it together – together with the Iridium team, our customer with whom we worked all these years much more as a partner than as a customer, together with Northrop Grumman, with all our subcontractors, and with SpaceX. I'm convinced this one-team spirit was the secret of that success story."
- The new Iridium Certus 9770 transceiver, also introduced during today's press conference, is a game changer for satellite IoT, aviation, maritime and consumer services, enabling low-cost, small devices that can make more efficient and higher speed connections than its predecessors. Built on the Iridium Certus technology platform, applications and devices made with the new transceiver will feature a range of speeds optimized for efficiently sending data to and from the user, typically in the range of less than 100 kbit/s. The Iridium Certus 9770 is the first in a series of new devices that will augment Iridium's existing transceivers with approximately the same form-factor as existing narrowband antennas used widely today in aviation, maritime, IoT and land-mobile markets, but using native IP technology at up to 35 times the speed as current devices. This supports telemetry, pictures, high-quality voice calling, emails, internet access and more, at highly competitive prices. Select licensed manufacturers of Iridium can expect to receive prototypes of the device around mid-2019.
- The Iridium satellite network is comprised of 66 crosslinked satellites that create a web of coverage around the entire planet. Unlike other satellite systems, Iridium's crosslinked architecture enables real-time transit of data to and from any location on the globe without the need for abundant ground stations and allows it to maintain consistent, high-quality coverage, including over the oceans and polar regions.
• January 21, 2019: After months of testing Network Innovations (NI) is giving the nod to the new Iridium CertusSM service. With global teams conducting vigorous testing, NI has been able to gain first-hand expertise and in-depth knowledge of both the service and the hardware while assisting Iridium in preparing for the commercial launch. 52)
- Network Innovations, one of the first Iridium Certus Service Providers, has been beta- and field-testing the new Iridium CertusSM service. NI’s prelaunch activities and expansive field-testing have combined to increase NI’s value proposition for global customers.
- Since 1996, Network Innovations has been involved in testing every new L-Band satellite service. In addition to a global reach, NI’s experience of beta-testing and reporting were the deciding factors for Iridium to choose NI to put the new system through its paces in preparation for the launch.
- The lessons learned through the process of beta- and field-testing provided NI’s team a uniquely complete understanding of the service’s functionality and allowed them to hit the ground running both on the support and sales side. This resulted in early customer adoption with one of the first commercial activations globally. Network Innovations has sold, delivered and activated commercial Iridium Certus units in both Land and Maritime clients and will deliver its first Aero units later this year.
- Eric Verheylewegen, Executive Vice President, Global Land Sales, Network Innovations said that Iridium Certus is a true game changer as it gives their clients the ability to connect at high speed, on the move, globally no matter their latitude. Combined with three simultaneous crystal-clear voice lines, Iridium Certus is the perfect solution for their clients who work in the most demanding environments. The upcoming increase in speed and suite of additional onboard services will increase the uniqueness of the Iridium Certus service, making it one of the most attractive tools in their solutions portfolio.
- Bryan Hartin, executive vice president, Iridium added that Network Innovations is a long-time trusted partner of Iridium and an ideal company to help them bring Iridium Certus to the market, in addition to putting it through the paces and helping ensure it was ready for commercial service introduction. This service is bringing smaller, lighter, faster and more cost-effective terminals to an L-band industry market sorely in need of a new choice for its critical communications applications.
- All 10 satellites have successfully communicated with the Iridium Satellite Network Operations Center and are preparing to undergo initial on-orbit testing. This was the eighth and final launch for Iridium's historic launch campaign with SpaceX, seeing a total of 75 new satellites deployed over less than two years.
- Iridium has invested approximately $3 billion to replace its original satellite system with a new, state-of-the-art network, ushering in an era of financial and technological transformation for the company. At the core of this transformation is the dramatic change in cash flows as construction capital expenses end and a decade or longer "capex holiday" allows significant cash generation from existing and new services. These include Iridium CertusSM, which will provide the world's fastest and only truly global specialty L-band broadband connectivity, enabling highly mobile internet access using smaller and more cost-effective terminals, and the AireonSM aircraft surveillance system, extending real-time visibility of aircraft for air traffic controllers and airlines to the entire planet for the first time.
- "It has been an honor to deliver 75 new Iridium NEXT satellites to orbit. Matt and the entire Iridium NEXT team have been incredible to work with," said Gwynne Shotwell, President and Chief Operating Officer at SpaceX. "On behalf of all of our employees, congratulations to Iridium on achieving this incredible milestone."
- The Iridium satellite constellation is unlike any other in orbit and is the only communications network with pole-to-pole coverage of the entire planet. It is comprised of six polar orbiting planes, each containing 11 crosslinked satellites totaling 66 in the operational constellation, creating a web of coverage around the Earth. The 10 Iridium NEXT satellites launched as part of this final mission were deployed to orbital plane three. Since the launches began, the constellation has been undergoing a one-for-one replacement, new satellite for old, achieved through a highly choreographed in-space maneuver known as a "slot swap."
- "There are few words to describe what it feels like to complete a vision started many years ago when I joined the company and what it means for Iridium and our future," said Iridium CEO Matt Desch. "Our gratitude to SpaceX for helping bring this new generation of satellites to orbit, so flawlessly every time is beyond words. However, for Iridium, we're not quite across the finish line yet, as there is still some work to do to put these satellites into operation. Once that's complete, our future will be in place. I'm just incredibly proud of our team right now."
• November 5, 2018: Aireon LLC and FlightAware today announced that GlobalBeaconSM is live and providing airlines with global flight tracking ahead of the ICAO (International Civil Aviation Organization) GADSS (Global Aeronautical Distress Safety System) recommendations, which will be effective 8 November 2018. GlobalBeacon provides airlines with minute-by-minute global aircraft tracking for their aircraft at all times, anywhere in the world. 55)
- GlobalBeacon is a first of its kind, turnkey solution that surpasses GADSS standards and recommended practices for flight tracking. By combining FlightAware’s data processing platform and web-interface, with Aireon’s space-based ADS-B (Automatic Dependent Surveillance-Broadcast) network, GlobalBeacon transcends borders and Flight Information Regions (FIRs) and eliminates coverage gaps in polar airspace, over deserts and in oceanic regions. At the heart of GlobalBeacon’s capability is an aggregation of tracking information from Aireon’s space-based ADS-B network and FlightAware’s contextual flight data – including origin, destination, flight plan route and estimated time of arrival (ETA).
- Now live, GlobalBeacon enables airlines of all sizes to proactively position themselves to respond in the event of an emergency. It facilitates communication between the aircraft operator and the controller with constant fleet monitoring, automated distress alerts and tools that make it easy to share information.
“FlightAware and Aireon announced the development of GlobalBeacon back in September 2016. Now, we are days away from ICAO GADSS recommendations for flight tracking going into effect. We have a live solution that not only exceeds the recommendations for 2018, but also includes the components already ahead of the requirements for 2021,” said Aireon CEO, Don Thoma. “We are extremely proud of the partnership we have cultivated with FlightAware, and through this partnership, space-based ADS-B is already operational through many airlines and aircraft operators.”
- “GlobalBeacon provides a cost-effective and easy-to-deploy solution that exceeds all GADSS standards and recommended practices for flight tracking. It’s designed to work in conjunction with existing processes and tools commonly used by aircraft operators, making it easy to implement and use with any airline size. By leveraging existing ADS-B technology, GlobalBeacon has a unique advantage over other potential solutions because it typically does not require any new hardware or equipment to be installed on or in the aircraft,” said FlightAware CEO, Daniel Baker.
- In late September 2016, it was announced that Qatar Airways would be the first airline to adopt the new GlobalBeacon technology that would feed directly into their Integrated Operations Center. From the beginning of the product development cycle, Qatar Airways has been involved in beta testing and validation of GlobalBeacon. “Right after we announced the creation of GlobalBeacon, Qatar Airways joined as GlobalBeacon’s launch customer. With their involvement early on, we’ve been able to test and validate the product and ensure that it incorporates best practices for global flight tracking and fleet monitoring,” said Baker.
- Qatar Airways Group Chief Executive, His Excellency Mr. Akbar Al Baker, said: “We are thrilled to have been the first airline to use space-based ADS-B technology, and we are honored to collaborate with both Flight Aware and Aireon on the development of this solution. As one of the fastest growing leading airlines in the world, our goal is to consistently deliver the best service to all our customers. GlobalBeacon seamlessly integrates with our existing ICAO 2018 compliant flight watch technology (Total Operations System), and further enhances the safety of our operations and fleet management by providing updates every minute or less.”
- Aireon is deploying a space-based air traffic surveillance system for Automatic Dependent Surveillance-Broadcast (ADS-B) equipped aircraft throughout the entire globe. Aireon will harness next-generation aviation surveillance technologies that are currently ground-based and, for the first time ever, extend their reach globally to significantly improve efficiency, enhance safety, reduce emissions and provide cost savings benefits to all stakeholders. Realtime ADS-B surveillance will cover oceanic, polar and remote regions, as well as augment existing ground-based systems that are limited to terrestrial airspace. In partnership with leading ANSPs (Air Navigation Service Providers) from around the world, like NAV CANADA, the Irish Aviation Authority (IAA), Enav, NATS and Naviair, as well as Iridium Communications, Aireon will provide a global, realtime, space-based air traffic surveillance system to all aviation stakeholders.
- FlightAware is the world’s largest flight tracking data company and provides over 10,000 aircraft operators and service companies as well as over 12,000,000 passengers with global flight tracking solutions. FlightAware leverages data from air traffic control systems in over 45 countries, from FlightAware’s network of over 8,000 ADS-B ground stations in over 200 countries and using global datalink.
• September 25, 2018: Iridium Communications Inc. announced today that it has been selected as the preferred provider of satellite communications services for The Ocean Cleanup, the non-profit organization deploying advanced technologies to rid the world's oceans of plastic. The Ocean Cleanup is embarking on one of the largest environmental initiatives of this generation by cleaning up ocean plastic debris, starting with what's known as the Great Pacific Garbage Patch. The Ocean Cleanup has chosen Iridium L-band satellite broadband services to support this important mission. The service is being delivered in partnership with Iridium service provider The AST Group. 56)
- By creating a system of 600-meter-long floating plastic collectors (floating screens, or systems) that include a 3-meter-deep skirt, The Ocean Cleanup collects plastic pollution through a combination of the wind, waves, natural ocean currents and the floating screen's ability to prevent plastic escaping underneath it, or flowing over the top, while avoiding to ensnare sea life. Each system is equipped with two Iridium broadband terminals, and upon full deployment of a fleet of 60 floating screens, there will be 120 Iridium broadband terminals operating as part of this project. The Iridium terminals will be relaying critical systems data including compartment flood detection, position and location information, pictures, 360 degree video and system performance information.
- "The opportunity to play a role in such an important and historic endeavor was a no-brainer for Iridium. It's an honor for us to be a part of The Ocean Cleanup's incredible mission to rid the oceans of plastics," said Iridium CEO Matt Desch. "A reliable, predictable and redundant communication network, that can work despite adverse weather conditions is critically important to this system, and that's when the Iridium network really shines. When the oceans aren't cooperating and several foot waves and powerful winds are causing havoc, the Iridium system will help make sure The Ocean Cleanup understands the operational status of each floating screen in the fleet."
- The Iridium broadband terminals will receive data from a complex combination of sensors and data gathering equipment hosted by each system. That information will then be relayed to The Ocean Cleanup's headquarters in Rotterdam in real-time. Iridium's unique constellation of 66 interconnected low-earth orbit (LEO) satellites requires no local ground infrastructure and provides the robustness, reliability and redundancy needed to ensure this critical data is delivered as expected.
- Iridium is nearing complete deployment of its next-generation satellite constellation, Iridium NEXT. The new constellation is completely replacing the previous network of 66 interconnected satellites. To date, there have been seven successful Iridium NEXT launches completed by SpaceX, deploying 65 new satellites. One launch remains before completion of the company's historic constellation refresh. In total, 75 new satellites are being launched to LEO, of which 66 will be in the active constellation, with nine on-orbit spares.
- Over 5 trillion pieces of plastic currently litter the ocean. Trash accumulates in 5 ocean garbage patches, the largest one being the Great Pacific Garbage Patch, located between Hawaii and California. If left to circulate, the plastic will impact our ecosystems, health and economies. Solving it requires a combination of closing the source, and cleaning up what has already accumulated in the ocean.
- To catch the plastic, act like the plastic. Waves, winds and currents make the plastic move in a certain manner. The same forces will act on our roaming systems, causing them to gravitate to the areas in the garbage patch with the highest concentration of plastic. The more cleanup systems released, the more plastic will be collected. Computation models show a full-scale deployment will lead to a 50 % reduction of the Great Pacific Garbage Patch in 5 years’ time.
• August 30, 2018: Iridium Communications Inc. and smart shipping pioneer Rolls-Royce Marine (RRM), signed a Letter of Intent in support of their autonomous vessel development program. Through this arrangement, RRM and Iridium will work together to explore incorporating Iridium’s next-generation L-band satellite broadband service, Iridium CertusSM, into the RRM suite of Ship Intelligence solutions. Iridium is the ideal partner for this project as the company operates the world’s largest, and only pole-to-pole, mobile commercial satellite constellation. 57)
- The result of this agreement is that RRM will have a resilient and reliable broadband capability that can serve as a standalone option or high throughput backup, while expanding the reach of autonomous vessels to all the world’s waterways.
- RRM’s solutions deliver multifaceted enhancements to ships, enabling remote diagnostics, operations and performance monitoring capabilities. Among many offerings, these solutions provide remote access to onshore operators and control centers, delivering real-time connectivity and automation. The positive results are that by automating processes such as navigation, crew are able to focus on more valuable areas of vessel operations helping to streamline overall functionality, ushering in a new digital era of shipping.
• August 20, 2018: In the first quarter of 2019, AireonSM will offer a public service to the world’s aviation industry for the locating and tracking of ADS-B equipped aircraft in emergency situations. The Aireon ALERT (Aircraft Locating and Emergency Response Tracking) is the aviation industry’s first and only free, global, real-time emergency aircraft location service. Air Navigation Service Providers (ANSPs), aircraft operators, regulators and search and rescue organizations in need of crucial aircraft location data, can rely on Aireon ALERT to help provide an ADS-B OUT 1090 MHz equipped aircraft’s most recently known position. As a free service, Aireon ALERT will fill a critical need, ensuring search and rescue personnel have the most accurate aircraft position data available when responding to an incident, regardless of global location. 58) 59)
- Aireon ALERT will utilize Aireon’s spaceborne ADS-B data and will be operated by the Irish Aviation Authority (IAA). The Aireon ALERT 24/7 communications facility is located at IAA’s North Atlantic Communications Centre in Ballygirreen, Ireland. Aireon ALERT users do not have to be customers of Aireon or IAA. Users simply have to register for the free, emergency service.
- Why is Aireon ALERT needed? — Before the AireonSM space-based ADS-B system, real-time aircraft tracking and surveillance was not possible for the entire planet. Remote, oceanic and polar regions had little-to-no real-time air traffic surveillance. This was not just a tremendous inefficiency, but had safety, financial and environmental consequences. As a result, the ability to know the location of an aircraft in distress, while over remote or oceanic airspace is a new, invaluable asset, especially in emergency situations where just a few minutes of time can make a difference.
- Pre-registration for Aireon ALERT will be begin in August 2018.
- Peter Kearney, CEO of the IAA, said that the organization is proud to host and operate the world’s first truly global aircraft locating and emergency response tracking facility, based on the AireonSM system’s capabilities. The AIA facility will be providing Aireon ALERT services 24 hours a day, seven days a week, 365 days a year. As long as an aircraft is broadcasting on 1090 MHz ADS-B, IAA will be able to locate it anywhere worldwide. This is a unique and secure cloud-based service, designed to the highest data protection standards.
We'll soon have ten times more satellites in orbit - here's what that means 60)
• July 30, 2018: The Iridium-7 mission has successfully launched from the Vandenberg air force base in California, placing the latest ten satellites from the American company's second-generation network into orbit. Deployed by Elon Musk's SpaceX, Iridium now has 65 new NEXT satellites in the sky, just one away from the intended total. The plan is to be fully operational by the autumn. 60)
- Iridium provides satellite phone services and other communications support to everyone from the US government to airlines, from mining companies to mountaineers. With around 500,000 billable subscribers on the books, the company aims to drive that upwards with the new network.
- It will offer enhanced connectivity and broadband speeds for a whole range of customers eager for secure data and communications in hard-to-access areas. It is also seen as having an important role to play in helping machines talk to one another in the Internet of Things, including driverless cars.
- Iridium's big selling point is that it is the only provider that offers truly global coverage. It competes with the likes of US rivals Globalstar and Orbcomm; and the UK's Inmarsat, which leads the market with a much smaller network of satellites at a higher orbit, whose attraction is ultra-reliability if you are in the right location. Iridium believes its NEXT offering will enable it to properly compete against Inmarsat on broadband for the first time.
- The company was set up in the late 1990s with heavy backing from Motorola to launch its original fleet of 77 satellites, and later bailed out by the US government when it ran out of money. With that first network approaching the end of its operational life, Iridium raised several billion dollars to buy 81 new satellites (the remaining 15 are spares). Iridium has already started taking the old satellites out of orbit.
• Alongside Iridium and the other established providers, a new generation of space companies is starting to emerge. The cost of launch is decreasing at a faster pace than at any time in the history of space exploration. Where traditional launch providers charge between US$14,000-17,000 per kg to put satellites in low Earth orbit, the Falcon 9 from Space X can do it for just under US$5,000. This will drop even further thanks to the emergence of launch systems that can be fully reused, like the SpaceX Falcon Heavy and also Falcon 9 Block 5, which was used for the first time a few days ago.
- Soon to be joined by Jeff Bezos' Blue Origin rocket, the cost per kg could drop below US$2,000 in the near future. And with the development of smaller satellites and horizontal launch systems, such as the one proposed by Virgin Orbit, it could soon come down to even a few hundred dollars per kilo.
- The second crucial change in the offing is the miniaturization of satellite technology. This promises a shift away from the traditional architecture of large, heavy and expensive satellites like the Iridium NEXT and Globalstar networks towards "mega constellations" of much smaller devices. This threatens to have a major impact on the satellite broadband business.
- Until now, satellite broadband has had significant disadvantages compared to Earth-based alternatives like ADSL (Asynchronous Digital Subscriber Line) and fiber optic. Due to the distance the signals have to travel and the weather, there are issues with latency and sluggish responses, which is problematic for the likes of gamers. The speed of satellite Internet is substantially slower than even the cheapest cable-based provider. It's currently seen as little more than a back-stop in rural or hard-to-access areas.
- The vision is to use mega constellations of satellites to disrupt the domestic and home broadband market with affordable, low-latency, global Internet coverage at speeds comparable to ASDL. At the forefront is OneWeb, a US-based start-up launching the first in its series of satellites later this year. It hopes to have "fully bridged" the divide with cable-based broadband by 2027.
- Where Iridium NEXT uses 66 satellites weighing 860 kg each, OneWeb is starting with over 640 satellites, each weighing 150 kg. Other companies, meanwhile, such as the UK's Sky and Space Global, are proposing to use a constellation of 200 very small satellites, each only weighing 10 kg, to provide voice or text communications on mobile phones to people in hard-to-access areas.
- The picture becomes even more competitive when the ambitious plans of SpaceX are factored in. Elon Musk is looking to do much more than be a launch provider. In 2016, SpaceX announced a plan to launch a mega constellation of over 4,000 satellites providing global high-speed broadband by the mid-2020s
• There are currently 1,738 active satellites in orbit. Mega constellations will increase that by an order of magnitude in the next few years. As well as the strain on bandwidth, the Earth's orbit is going to become much more congested.
- This raises important environmental questions. Some operators such as OneWeb have made encouraging noises about managing the end of life of their satellites, but serious concerns remain. There's an opportunity for the next generation of space entrepreneurs to be true pioneers by establishing a sustainable way of working in space.
- This aside, the industry's growth potential looks staggering. A recent report from Morgan Stanley predicted the space industry would grow from US$350 billion in 2016 to over US$1.1 trillion by 2040. But one vital question is, where will it leave incumbents like Iridium?
- These players have crucial advantages: above all, they are there. They have attracted the investment and have put the hardware into space. They offer an established platform based on reliable, proven technology; many customers will prefer that over cheaper, experimental solutions.
- Iridium argues that while it may not be able to offer broadband speeds to compete with new arrivals, its global coverage means it will continue to play a vital role offering back-up when other services fail. It also points out that its satellites operate on the L-band frequency, whereas the likes of OneWeb will be on the less reliable Ku-band.
- Whether the new arrivals and incumbents manage to carve out different segments of a bigger market will be fascinating to watch in the coming years. For my money, reliability will always trump everything else. But whatever happens, big changes are coming: the satellite communications business will look entirely different in ten years

• May 22, 2018: Iridium Communications Inc. announced today that at 19:47:58 UTC, SpaceX successfully launched five Iridium NEXT satellites from Vandenberg Air Force Base in California. The Iridium satellites were joined by the twin spacecraft for the NASA/German Research Center for Geosciences (GFZ) Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission, in a unique "rideshare" launch. Shortly after deployment, Iridium confirmed successful communication with all five new satellites, formally bringing the total number of Iridium NEXT satellites in orbit to 55. This leaves just two more launches of 10 satellites each to complete this ambitious launch program. The Iridium NEXT constellation, featuring 66 interconnected LEO (Low Earth Orbit) satellites, will enable never before possible services like the AireonSM global aircraft tracking and surveillance system and its new broadband service, Iridium Certus. 65)
• April 21, 2018: Iridium Communications Inc. announced today that the International Maritime Organization’s (IMO) Maritime Safety Committee (MSC) agreed to recognize that the Iridium network meets all the criteria of the IMO needed to provide mobile satellite services in the GMDSS (Global Maritime Distress and Safety System), and to adopt the “Statement of Recognition” proposed by the United States as a Committee Resolution. This is a significant achievement that ends a decades-long satellite industry monopoly in which only one company was authorized to provide satellite GMDSS service and for the first time will bring competition and truly global coverage, to mariners sailing any of the world’s oceans. 66)
- The MSC also agreed that Iridium and the United States, the delegation sponsoring Iridium’s application at the IMO, will work with the International Mobile Satellite Organization (IMSO), which will monitor progress in Iridium’s implementation of the service. The IMSO will report to the MSC once a Public Services Agreement has been entered into between Iridium and the IMSO, likely marking the start of this service.
- “This is a historic moment for the maritime industry and an honor for Iridium to be the second ever recognized provider for GMDSS services,” said Bryan Hartin, executive vice president, Iridium. “This is the dawn of a new era for mariner safety. We’ll bring a new choice and upgraded capabilities for mariners along with our truly global coverage that will for the first time extend the reach of satelliteborne GMDSS to even the most remote waterways.”
- Iridium formally began the process to become a recognized GMDSS mobile satellite service provider in April 2013. Iridium plans to begin providing GMDSS service in early 2020.
- “This has been a long time coming, and we are ecstatic to gain this very important recognition from the IMO. We are equally proud to ensure mariners will have access to this critical system from anywhere in the world that they sail,” said Matt Desch, chief executive officer, Iridium. “Iridium has established itself as a trusted maritime safety provider for over a decade, and this recognition is a testament to both that trust and the capabilities offered by our satellite network.”
- The announcement comes one day before Iridium is scheduled to launch its sixth Iridium NEXT mission with SpaceX, delivering five more Iridium NEXT satellites to low earth orbit as part of the continuing upgrade to its existing satellite network. The launch is scheduled for May 22nd at 12:47:58 pm PDT (19:47:58 UTC). The Iridium network is a constellation of 66 low-Earth orbit (LEO), cross-linked satellites that provide reliable, low-latency satellite communications to the entire world, including the poles.

• April 9, 2018: Iridium Communications Inc. has announced that the Iridium-6/GRACE-FO rideshare mission, the sixth Iridium® NEXT launch overall, has been targeted for launch by SpaceX from Vandenberg Air Force Base (VAFB) in California for 19 May 19 2018, at approximately 20:03 UTC. 68)
- The second of four Iridium launches planned for 2018, this mission will deliver five Iridium NEXT satellites to orbit, alongside the twin satellites for the NASA/German Research Center for Geosciences (GFZ) Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission. Collaboratively chosen by all parties and considering range availability, this launch date maintains scheduled completion of the Iridium NEXT manifest in 2018.
- This unique “rideshare” launch will first deploy the twin GRACE-FO spacecraft, after which the Falcon 9 second stage will continue onward to the deployment orbit for the five Iridium NEXT satellites. Upon completion, the Iridium-6/GRACE-FO mission will increase the total number of Iridium NEXT satellites in space to 55, leaving just two launches, of 10 satellites each, remaining. Iridium NEXT satellites are scheduled to begin shipping to the launch site this week while the twin GRACE-FO spacecraft are already onsite at the VAFB Harris Corporation facility, and have been stacked, attached to their dispenser and are preparing for transfer to the SpaceX launch complex.
- For this mission, all five Iridium NEXT satellites will be delivered to orbital plane six. The Iridium network is comprised of six polar orbiting planes, each containing 11 operational crosslinked satellites, for a total of 66 satellites in the active constellation. The 2018 Iridium NEXT launch series will bring a total of 35 new satellites to space, completing the constellation of 66 operational satellites and 9 in-orbit spares. In total, 81 new satellites are being built, with the six remaining satellites serving as ground spares.
• April 3, 2018: Iridium Communications' fifth set of 10 Iridium NEXT satellites, launched on 30 March by SpaceX, are functioning nominally and have started the testing and validation process — this fifth launch increased the total number of Iridium NEXT satellites in space to 50, and was also the second Iridium NEXT launch to use a flight-proven Falcon 9 rocket. 69)
- The Iridium constellation is comprised of six polar orbiting planes, each containing 11 operational cross-linked satellites, for a total of 66 satellites in the active constellation. This unique architecture creates a web of coverage around the earth, enabling Iridium to provide real-time communications over the oceans and from even the most remote locations. Three more Iridium NEXT launches are scheduled for 2018, to bring Iridium's total to 75 new satellites in orbit, including nine spares.
- Scott Smith, the COO at Iridium, said that once testing is complete, the company will be just 25 Iridium NEXT satellites shy of completing this historic tech refresh. It's inspiring to think about how Iridium is doing this for a second time and no one else has accomplished a feat of this magnitude in space — even once. Tests and diagnostics began just minutes after the new satellites deployed, and all systems are functioning nominally.
• On March 30, 2018 (14:14 UTC) SpaceX successfully launched the Iridium-5 mission from Space Launch Complex 4E (SLC-4E) at Vandenberg Air Force Base in California. This was the fifth set of 10 satellites in a series of 75 total satellites that SpaceX will launch for Iridium’s next generation global satellite constellation, Iridium® NEXT. The satellites were deployed about an hour after launch. 70) 71)
- Falcon 9’s first stage for the Iridium-5 mission previously supported the Iridium-3 mission from SLC-4E in October 2017. SpaceX did not attempt to recover Falcon 9’s first stage after launch.

• On February 19, 2018, Iridium Communications Inc. announced that COMSAT, Inc. has signed an agreement to become an Iridium Certus service provider for U.S. Department of Defense (DoD) users. This unique, long-term deal will allow COMSAT Inc. to provide Iridium’s secure global satellite broadband connectivity for mobile voice and data services to the DoD beginning in mid-2018. 75)
- COMSAT Inc.'s secure delivery combines with the advantages of the Iridium® network's global, on-the-move L-band connectivity. COMSAT will be able to deliver enhanced capabilities that meet Communications Security (ComSec) requirements for the DoD and warfighter. These capabilities include, but are not limited to, real-time usage statistics, telematics data, voice calling, personnel tracking applications, and real-time environmental assessments. Positive elements of Iridium Certus terminals is that they are smaller and capable of maintaining broadband connectivity in fast-paced, unpredictable environments on land, at sea, in the air—and can do it without landing or passing through non-U.S. territories. The service will debut at speeds of 352 kbit/s, with terminals upgradable to 704 kbit/s through a future firmware update.
• On 7 Feb. 2018, Iridium Communications Inc. announced the first Iridium Certus service providers for land-mobile applications, planned for commercial availability in mid-2018. This initial group of six world-class land-mobile service providers play a pivotal role in bringing Iridium Certus to market. Enabled by the Iridium® NEXT satellite constellation, Iridium Certus will deliver reliable, global broadband connectivity and high-quality voice service to the land-mobile industry. 76)
- Iridium Certus will extend the reach of terrestrial and cellular infrastructure like never before with truly mobile communications capabilities, making it ideal for supporting critical connectivity needs regardless of location, terrain and weather events. The service will feature a range of data speed options and will integrate with the robustly designed Thales MissionLINKTM terminal, providing a reliable connection for voice, satellite internet, cellular data, Land Mobile Radio (LMR) and location-based applications. With Iridium Certus, customers will be able to control costs by eliminating the need to deploy expensive ground-based infrastructure or large, expensive directional terminals that rely upon geostationary satellites.
- "Iridium Certus is going to change the way we think about connectivity for enterprise, government, and militaries on the move," said Josh Miner, executive director, land-mobile line of business at Iridium. "Regardless of location, customers will have access to reliable satellite connectivity to run more efficient operations while deployed in the field." Miner continued, "This flexible solution, when combined with the Thales MissionLINK satellite terminal, allows customers to automatically transition between satellite and cellular infrastructure when paired with an LTE terminal. Customers can configure their Thales satellite terminals to automatically switch to Iridium Certus satellite service when required, ensuring that the most cost-effective solution is deployed, while maintaining continuity."
- Additional land-mobile service providers are planned to be announced in the coming months. Iridium NEXT is the Company's next-generation satellite constellation which will replace its existing network. To date, there have been four successful Iridium NEXT launches, deploying more than half of the new constellation. Four additional launches are planned for the first half of 2018.
• December 27, 2017: Iridium Communications announced today that the fourth set of 10 Iridium NEXT satellites, launched on 22 Dec. by SpaceX, are functioning nominally and have begun the testing and validation process. Not only did this fourth launch mark the midway point of the Iridium NEXT launch campaign, it is also the first Iridium NEXT launch to use a flight-proven Falcon 9 rocket. 77)
- ”Since their deployment, the team has only positive news to report,” said Scott Smith, chief operating officer at Iridium. “Similar to the first three launches, our team at the Satellite Network Operations Center immediately began running initial diagnostics as soon as the newly deployed satellites were captured by our network, just minutes after they were deployed. This testing process has been running smoothly and will continue for several weeks, after which nine of the new satellites will begin their individual ascents to an operational orbit, replacing original vehicles. We’ll also be sending the tenth satellite to an adjacent orbital plane where it will go into service by Summer 2018.”
- The Iridium constellation is comprised of six polar orbiting planes, each containing 11 operational crosslinked satellites, for a total of 66 satellites in the active constellation. This unique architecture creates a web of coverage around the Earth, enabling Iridium to provide real-time communications over the oceans and from even the most remote locations. Four additional Iridium NEXT launches are scheduled for the first half of 2018, bringing Iridium’s total to 75 new satellites in orbit, including nine spares.
• December 23, 2017: Iridium Communications Inc. announced today that at 5:27pm PST (1:27 UTC on Dec. 23), SpaceX successfully launched the fourth set of 10 Iridium NEXT satellites into orbit from Vandenberg Air Force Base in California. Today's launch marks the midway point of the Iridium NEXT launch program, and was the first Iridium launch to use a SpaceX flight-proven rocket. The first stage booster for Iridium-4 was previously used for Iridium-2, making Iridium the first company to reuse the same rocket booster (Ref. 39). 78)
- Each launch strategically delivers new satellites to specific orbital planes, so that the complete Iridium NEXT constellation will be operational as soon as possible after all launches are complete. The Iridium network is comprised of six polar orbiting planes, each containing 11 operational crosslinked satellites, for a total of 66 satellites in the active constellation. Of the 10 Iridium NEXT satellites launched today, nine were delivered to their operational orbital plane, and the tenth is set to drift to an adjacent orbital plane. Once fully deployed, Iridium NEXT will blanket the earth with satellite connectivity, enabling broadband connectivity from even the most remote parts of the planet.
- "Today's launch is an incredible milestone — we have officially reached the halfway point," said Matt Desch, chief executive officer, Iridium. "It was an amazing sight to see the Iridium-2 booster back in flight today, carrying Iridium-4 into space. We are excited to be taking part in SpaceX's rocket reusability initiative and make history as the first company to reuse the same booster." Desch continued, "With over half of the new constellation now in orbit, momentum around the testing of our new broadband service, Iridium CertusSM, will continue to progress quickly. I know our customers are very excited about our expanding capabilities."
- Iridium NEXT is not only delivering faster data speeds and other new capabilities with Iridium Certus, but also enabling revolutionary technologies from the hosted payloads onboard each satellite. Among these are the AireonSM realtime aircraft surveillance payload and the maritime AIS (Automatic Identification System) payload, co-operated by Harris Corporation and exactEarth. That payload, known as exactViewTM RT (Real Time) powered by Harris, provides global realtime ship and vessel tracking across all the earth's oceans. Through the Aireon and exactView RT hosted payloads, both built by Harris Corporation, the Iridium NEXT satellite constellation is the only system capable of providing global, realtime surveillance and tracking of aircraft and ships.
• November 28, 2017: Iridium Communications Inc. has announced that all 10 Iridium® NEXT satellites for the company's fourth launch are now being processed at SpaceX’s west coast launch site at VAFB (Vandenberg Air Force Base) in California. This launch will mark the midway point of Iridium’s launch campaign with SpaceX and is the first of two Iridium NEXT launches using “flight-proven” SpaceX Falcon 9 rockets. Iridium-4 is currently scheduled for December 22. 80)
• October 19, 2017: Iridium Communications Inc. announced today that the fourth Iridium NEXT launch has been targeted by SpaceX for December 22, 2017 from VAFB. This launch signifies the mid-way point of the Iridium NEXT launch program and will deliver another 10 satellites to orbit, bringing the total number deployed to 40. Targeted for just over two months after the third Iridium NEXT launch, this December date enables Iridium to maintain its planned cadence of completing all launches by mid-2018, even with SpaceX's busy launch manifest. 81)
• October 11, 2017: Iridium Communications announced today that the third set of 10 Iridium NEXT satellites, launched on 9 October by SpaceX, are functioning nominally and have begun the testing and validation process. 82)
- Scott Smith, chief operating officer at Iridium said that since launch success, all things are pointing positive, and the team at the SNOC (Satellite Network Operations Center) in Leesburg, VA, is ready and has already been working around the clock since their deployment. Unlike previous launches, where some satellites were sent drifting to their operational orbital plane, all 10 satellites from this launch will go directly into operation once testing is completed. This phase of satellite maneuvers and testing is where the Iridium satellite network operations teams truly shine.
- Now, and for approximately the next 45 days, these newly launched satellites will undergo a series of testing and validation procedures, ensuring they are ready for integration with the operational constellation.
- Once testing is completed, Iridium will also hand over control of Aireon’s ADS-B (Automatic Dependent Surveillance-Broadcast) hosted payload, to the team at Aireon’s HPOC (Hosted Payload Operations Center), also in Leesburg, Virginia.
• October 9, 2017: Iridium Communications Inc. announced today the successful third launch and deployment of 10 Iridium NEXT satellites. The satellites were delivered into low-Earth orbit approximately one hour after a SpaceX Falcon 9 rocket lifted off from Vandenberg Air Force Base in California at 5:37 a.m. PDT (12:37 UTC). With two successful launches having already been completed this year, this third batch of 10 satellites brings the total number of Iridium NEXT satellites in orbit to 30, nearly half the amount required for a full Iridium NEXT operational constellation. 83)
- While already able to deliver fully global communications coverage, the Iridium constellation is undergoing a technological transformation. At the center of this transformation are three new capabilities; Iridium CertusSM, the company's new L-band broadband service; Aireon's space-based automatic dependent surveillance-broadcast (ADS-B) hosted-payload, that will provide real-time tracking and surveillance of all ADS-B equipped aircraft globally; and Harris Corporation and exactEarth's ship tracking service.
- "Each successful launch brings us one step closer to both a technological and financial transformation," said Iridium CEO, Matt Desch. "One of our core strategies is to offer new services that are either flat out impossible or not easily replicated by more traditional "bent pipe" and geostationary systems. Satellite Time & Location, Short Burst Data® and Iridium PTT are just a few examples of global services only possible on our network. For us and our partners, Iridium NEXT is an engine for innovation, and services like these are just the start. Moreover, we're on track to completion in 2018.”
- Iridium NEXT is the company's next-generation satellite constellation, replacing and enhancing its existing network of interconnected, low-Earth orbit satellites spanning the entire globe — the largest commercial satellite constellation in space. The constellation's unique architecture features interconnected satellites that form a web of coverage around the earth, enabling connectivity over the oceans, in the poles and other remote areas.
- The Iridium NEXT system and satellites have been designed and managed by Thales Alenia Space, serving as prime contractor for the program. The satellites are integrated at Thales Alenia Space's subcontractor, Orbital ATK's, satellite manufacturing facility in Arizona. Thales Alenia Space and Orbital ATK are managing a state-of-the-art, high production rate assembly line system, similar in approach to the process that built the first Iridium satellite constellation over twenty years ago.
- Iridium and SpaceX are partnered for a series of eight launches, seven deploying 10 Iridium NEXT satellites at a time and one deploying five. A total of 81 Iridium NEXT satellites are being built, with 66 required for the operational constellation. A total of 75 satellites are currently planned for launch with nine of those serving as on-orbit spares and the remaining six as ground spares. The entire Iridium NEXT network is scheduled to be completed by mid-2018.
• September 27, 2017: Iridium Communications Inc. today announced a new long-term agreement bringing the truly global coverage and reliability of the Iridium® network to Hitachi Construction Machinery Co., Ltd.'s world class Global e-Service construction machinery management system. By integrating Iridium connectivity, Hitachi Construction Machinery's Global e-Service will now be able to expand to regions and markets previously not possible. Together, Iridium and Hitachi Construction Machinery are making effective, reliable and truly global, construction machinery management possible for Hitachi Construction Machinery's vast telematics customer base. 84)
- Hitachi Construction Machinery's Global e-Service construction machinery management system provides customers with robust maintenance information to help companies control CO2 emissions, minimize idling times and monitor fuel consumption. Through this new agreement, Global e-Service customers will be able to easily access and transfer critical data, that convey key operational information, including but not limited to, daily operation hours, temperatures and pressures. Quake Global, a key Iridium hardware manufacturer, provides its Iridium satellite network-based product for Hitachi Construction Machinery to integrate Global e-Service with the network.
- Iridium's network is uniquely qualified for mobile telematics and serving the Internet of Things (IoT) beyond the reach of terrestrial networks, due to the inherent advantages it boasts. Iridium operates the only 100-percent global network comprised of interconnected LEO satellites. Due to its proximity to Earth in LEO, Iridium's network delivers low-latency and reliable connectivity supporting critical business functions, like remote asset tracking, vehicle management and preventative maintenance. With constantly moving satellites that can communicate with each other, end users have access to enhanced reliability and connectivity, even in the most remote locations.
• June 25, 2017: Iridium Communications Inc. announced today the successful second launch of its next-generation network, Iridium NEXT. This payload of 10 satellites was deployed into low-Earth orbit, approximately one hour after a SpaceX Falcon 9 rocket lifted off from Vandenberg Air Force Base in California, at 1:25pm PDT (20:25 UTC). With this launch complete, there are now 20 Iridium NEXT satellites in orbit, establishing the infrastructure for groundbreaking technologies such as Iridium Certus and Aireon’s space-based Automatic Dependent Surveillance-Broadcast (ADS-B) aircraft tracking and surveillance service. Iridium Certus is poised to disrupt industry norms by enabling truly global L-band satellite broadband speeds through smaller, more cost-effective antennas. 85) 86)
- Since the successful January 14, 2017 launch, Iridium NEXT satellites have already been integrated into the operational constellation and are providing service. The first eight operational Iridium NEXT satellites are already providing superior call quality and faster data speeds with increased capacity to Iridium customers. The two additional satellites from the first launch are continuing to drift to their operational orbital plane, where upon arrival they will begin providing service. Iridium NEXT satellites from today’s launch will be tested and integrated into the constellation over the coming weeks. Just as with the first launch, on-orbit testing and validation will be completed by the Iridium and Thales Alenia Space teams. Five of the 10 satellites from this launch will be sent to adjacent orbits (“planes”) to optimize the network deployment and ensure eleven operational satellites, and at least one in-orbit spare, are in each of Iridium’s six polar orbiting planes following full deployment.
- “Right now, it’s two down with six more launches to go,” said Matt Desch, chief executive officer, Iridium. “Our operations team is eagerly awaiting this new batch of satellites and is ready to begin the testing and validation process. After several weeks of fine-tuning, the next set of ‘slot swaps’ will begin, bringing more Iridium NEXT satellites into operational service, and bringing us closer to an exciting new era for our network, company, and partners.”
- Among the many technologies enabled by Iridium NEXT is a unique hosted payload from Iridium’s partner, Aireon, which will provide a real-time, global aircraft surveillance and tracking service. Today, air traffic controllers and aircraft operators face the problem of being unable to see the location of aircraft at all times, worldwide. This is largely due to the lack of aircraft tracking infrastructure on the ground in remote regions and over the oceans. The AireonSM system is designed to solve this problem. To date, more than one billion aircraft position reports have been received by the first eight operational Aireon payloads, activated after the first Iridium NEXT launch this past January.
- “Since first launch, our technology has exceeded all expectations,” said Don Thoma, chief executive officer, Aireon. “With just eight payloads, we have seen an incredible amount of data, from aircraft and vehicle antennas of both high and surprisingly low wattage. We’ve conducted flight tests with the FAA and NAV CANADA, which were designed to really push our system’s limits, while also helping to fine-tune its capabilities. We’re on a path to revolutionizing how the world sees the skies, and with each launch come one step closer to making it a global reality.”
- According to analyses conducted by the Flight Safety Foundation and Purdue University’s School of Aeronautics and Astronautics, spaceborne ADS-B, utilized by the Aireon system, can increase safety while also reducing the environmental impact of the aviation industry.
- Through a series of eight launches, SpaceX will deliver 75 Iridium NEXT satellites to low-Earth orbit, with 66 making up the operational constellation. In total, 81 new satellites are being built, with nine serving as on-orbit spares and six as ground spares. The satellites were designed by Thales Alenia Space, which serves as system prime contractor, and are being integrated by Thales’s subcontractor, Orbital ATK, at its Satellite Manufacturing Facility in Arizona. The production process features an 18-station, state-of-the-art assembly line system for all 81 Iridium NEXT satellites.
• May 26, 2017: For an unusual change, a launch date just got moved forward. Usually date changes are to push the event further out ... not so for Iridium Communications second launch for the Iridium NEXT satellite constellation. The date is now targeted for June 25, 2017 at 1:24:59 p.m. PDT with an instantaneous launch window. 87)
- SpaceX informed Iridium that range availability had opened up at VAFB (Vandenberg Air Force Base) in California, where SpaceX’s west coast launch facility is located, and planned to target Iridium’s launch four days earlier than originally scheduled. This launch will deliver the second payload of 10 Iridium NEXT satellites to orbit, bringing the total to 20 Iridium NEXT satellites in space.
• May 2, 2017: Iridium Communications Inc. has announced that the first set of Iridium NEXT satellites have been integrated into the operational constellation and are providing excellent service to Iridium customers. Prior to achieving this major program milestone, the new satellites went through a rigorous testing and validation process that demonstrated that they met all performance requirements and even exceeded many. The Iridium NEXT satellites are already providing superior call quality and faster data speeds with increased capacity to Iridium customers. In addition, the Company has announced the targeted launch date for the second payload of ten Iridium NEXT satellites as June 29, 2017, at 1:02pm PDT, with an instantaneous launch window. 88)
- The testing and validation process for the Iridium NEXT satellite constellation involved a thorough test of each of Iridium's services, an assessment of each satellite's performance against established metrics, and a formal acceptance process between Iridium and Thales, thus ensuring a smooth integration into Iridium's existing network architecture. Once completed for each new satellite, a precisely orchestrated process of replacing the original Iridium® satellite with a new Iridium NEXT satellite, known as a ‘slot swap' is completed. To date, the team at Iridium's SNOC (Satellite Network Operations Center) has successfully completed three individual slot swaps, and two dual slot swaps. Two of the new satellites are currently drifting to their assigned orbital plane.
- "To say that I am proud of the Iridium satellite network operations team is an understatement," said Scott Smith, chief operating officer at Iridium. "Conducting multiple slot swaps to replace a network of this magnitude is an incredible task, and only Iridium has the team and technical capacity to manage this project. We have been preparing for this process for years, and since first launch the team has worked non-stop to manage each maneuver to successfully integrate the new satellites into the active network. We are thrilled to say that these new satellites are exceeding expectations and are already delivering faster speeds to our customers."
• April 28, 2017: Eight of Iridium’s first ten upgraded communications satellites launched in January started providing voice and data relay service ahead of schedule, and SpaceX says it can launch up to 40 more Iridium spacecraft by the end of the year, Iridium officials reported on 28 April. “I’m happy to report that our initial batch of Iridium Next satellites are now fully operational and working very well,” said Matt Desch, CEO of Virginia-based of Iridium Communications. 89) 90)
- Engineers are repositioning the other two new-generation Iridium spacecraft in orbit to replace other satellites, part of a “highly-choreographed process” to complete a refresh of the company’s entire constellation by mid-2018, Desch said Thursday in a quarterly earnings call with investment analysts.
- The first eight Iridium Next satellites entered service in March and early April, taking the place of aging first-generation spacecraft launched in the late 1990s.
- After their deployment from the second stage of a SpaceX Falcon 9 rocket launched from Vandenberg Air Force Base in California, the satellites boosted their altitude from a 625 km drop-off orbit into the operational constellation at an altitude of 780 km alongside the craft they were intended to replace. - Ground controllers then instantaneously switched off the inter-satellite communications links on the old satellite and turned on the links on the new craft, a procedure Iridium calls a slot swap.
- The Iridium fleet consists of 66 operational satellites distributed in six orbital tracks, with 11 slots in each plane. The remaining two Iridium Next satellites, deployed into Plane 6 on Jan. 14, are drifting into a different plane, a movement that will take around 10 months.
- “We completed the commissioning of these Iridium Next satellites about one week ahead of schedule, which is a real testament to the planning and preparation of our satellite operations team,” Desch said. “What’s important is that our experience with in-orbit testing, slot swaps and the new satellite performance gives us confidence that we’ll be able to manage the roughly 60-day launch cycle (we’re) targeting following the second launch.”
- Iridium’s next 10 satellites are set for launch June 29 aboard another Falcon-9 booster. Desch said the spacecraft will begin shipping from their factory in Gilbert, Arizona, to the Vandenberg launch base in mid-May for fueling and attachment with the rocket’s multi-payload dispenser, which accommodates the 10 satellites inside the Falcon-9 nose cone.
- The Iridium Next assembly line in Arizona, managed by Orbital ATK in partnership with satellite-designer Thales Alenia Space, is producing spacecraft at a rate to manufacture all of the Iridium Next satellites by the end of 2017, Desch said.
- Iridium originally planned to launch 70 of the Iridium Next satellites on seven Falcon-9 rockets by the end of 2017, but SpaceX launch delays caused by rocket failures and production bottlenecks have pushed that target to mid-2018.
• February 23, 2017: Since the first 10 Iridium NEXT satellites were successfully launched and deployed on January 14th, they have undergone a series of rigorous testing and validation in preparation for their insertion into the network. Today Iridium announced the first satellite, space vehicle (SV) 106, is now active in the network, carrying live voice and data communications within our global network. 91)
• February 15, 2017: Iridium Communications Inc. announced it has received a targeted launch date of mid-June 2017 for the second mission of 10 Iridium NEXT satellites. Originally anticipated for mid-April of 2017, the date has shifted due to a backlog in SpaceX’s launch manifest as a result of last year’s September 1, 2016 anomaly. This second launch will deliver another ten Iridium NEXT satellites to LEO on a SpaceX Falcon-9 rocket. SpaceX is targeting six subsequent Iridium NEXT launches approximately every two months thereafter. 92)
- "After such a successful first launch, we are eager to maintain the momentum until our network is completed," said Matt Desch, chief executive officer at Iridium. "Even with this eight week shift, SpaceX's targeted schedule completes our constellation in mid-2018."
- This announcement comes as Iridium has successfully connected the first Iridium NEXT satellite via its crosslinks into its global LEO constellation. The new satellite is expected to begin providing service to Iridium customers in the coming days. This marks a major milestone for the Iridium NEXT program as the testing and validation phase is ahead of schedule and the satellites are working well.
- "Our team at our Satellite Network Operations Center has been working around-the-clock to confirm the health and performance of these new satellites," said Scott Smith, chief operating officer at Iridium. "Since their perfect orbit injection and deployment by SpaceX, our satellite testing process has progressed ahead of schedule, a testament to the rigorous development program they've undergone on the ground."
- The upcoming mid-June launch will mark the second mission of eight Iridium NEXT launches with SpaceX, including the recently announced satellite rideshare with NASA and GFZ's (Potsdam, Germany) GRACE-FO (Gravity Recovery and Climate Experiment Follow-on) mission. In total, Iridium currently has plans to launch 75 Iridium NEXT satellites — 66 to serve as operational satellites and nine as on-orbit spares.
• January 18, 2017: On the heels of a successful launch of the first ten Iridium NEXT satellites on Saturday, January 14th, Aireon announced today that it has signed a data services agreement with Isavia, the Icelandic Air Navigation Service Provider (ANSP). Isavia will deploy Aireon’s spaceborne ADS-B (Automatic Dependent Surveillance-Broadcast) service throughout the Reykjavik Oceanic Control Area (OCA). In addition to providing enhanced redundancy to existing terrestrial surveillance resources in the southern part of the airspace, the AireonSM service will, for the first time ever, provide real-time surveillance and tracking in the region extending from 70º north to the North Pole. 93)
- With control of more than 5.4 million square kilometers of airspace, Isavia is looking to improve safety, and efficiency (through reduced separation) of operations by expanding the ADS-B service area. Continuity of service will be enhanced through use of Aireon’s technology in airspace where line-of-sight surveillance is already.
• January 19, 2017: SpaceX was able to celebrate a successful return to flight this week with a picture-perfect launch of the Falcon-9 rocket on January 14, 2017 that successfully delivered a fleet of ten advanced Iridium NEXT mobile voice and data relay satellites to orbit. But the icing on the cake was the dead-center landing and recovery of the Falcon-9 booster on their drone barge in the Pacific Ocean, off the west coast of California. 94) 95)
• December 30, 2016: The first 10 satellites for Iridium’s next-generation mobile voice and data relay network have been fueled, joined with their deployment module and encapsulated inside the clamshell-like nose cone of a SpaceX Falcon-9 booster for launch as soon as next week from VAFB (Vandenberg Air Force Base) in California. 17)
- An official target launch date is pending the FAA (Federal Aviation Administration) approval of the SpaceX-led investigation into the explosion of a Falcon-9 rocket on a launch pad at Cape Canaveral on Sept. 1, 2015, which destroyed the Israeli-owned Amos-6 communications satellite awaiting liftoff a few days later.
- SpaceX missions have been grounded since the explosion. The California-based launch company, founded and headed by Elon Musk, hoped to resume launch services by the end of 2016, but the investigation, launch preparations, and the FAA’s review of the Sept. 1 mishap pushed the Falcon-9’s return-to-flight into January.
- The launch of Iridium’s first 10 next-generation communications satellites, the first part of an eventual network of 81 spacecraft, was next in line on SpaceX’s manifest at the time of the Sept. 1 explosion.
- Meanwhile, construction crews at Kennedy Space Center’s launch pad 39A in Florida are finishing up modifications to the former space shuttle launch complex to support Falcon 9 flights as soon as late next month. - The launch facility used by SpaceX’s previous missions from Cape Canaveral, Complex 40, suffered major damage after the Sept. 1 rocket explosion, the first such on-the-ground mishap at the Florida spaceport since the early years of the Space Age.
Legend to Figure 3: The satellites are mounted on a deployment module developed by SpaceX specifically for the Iridium missions to be flown on Falcon 9 rockets. SpaceX is under contract to launch at least 70 Iridium Next satellites through early 2018, primarily in batches of 10 at a time. The mounting system is made up of two tiers, each holding five satellites. Ground crews inside the SpaceX payload processing facility at Vandenberg have stacked the two tiers and encapsulated the satellites inside the Falcon 9’s payload fairing, which is emblazoned with the Iridium logo.
• June 14, 2016: Iridium Communications Inc. announced that its first Iridium NEXT satellites have completed assembly and testing, and are now prepared for shipment to the launch site at Vandenberg Air Force Base in California. The shipment of these satellites represents a significant milestone toward the first launch of the Iridium NEXT constellation, which the company officially announced as targeted for September 12, 2016. 18)
- Assembly, integration and testing of the satellites are performed by Thales Alenia Space and their subcontractor, Orbital ATK, at the Orbital ATK manufacturing facility in Gilbert, Ariz. The production process incorporates a unique, assembly line system consisting of 18 different work stations ranging from panel integration and payload testing to full satellite integration, solar array installations and alignment checks. Each satellite features more than 5,000 individual parts assembled, culminating in one hundred thousand hours of workmanship by hundreds of engineers. A total of 81 satellites are scheduled to roll off of this assembly line, with 66 serving as the operational satellites to replace the existing Iridium® network, and the remainder serving as ground and on-orbit spares.

A total of 81 satellites are scheduled to roll off of this assembly line, with 66 serving as the operational satellites to replace the existing Iridium® network, and the remainder serving as ground and on-orbit spares.
- The first two completed Iridium NEXT satellites are being shipped to Vandenberg Air Force Base for processing by Iridium's launch partner, SpaceX. As the remaining eight first-launch satellites are completed, they will also be shipped two at a time to the launch site. While the satellites will be ready by August, the earliest launch date available to Iridium from SpaceX and Vandenberg Air Force Base is September 12th. During processing, Orbital ATK is responsible for fueling the satellites, while also performing software validation and testing to ensure the satellites integrate properly with the SpaceX Falcon 9 rockets. The Iridium NEXT satellites represent SpaceX's heaviest payload to date.
- All Iridium NEXT satellites are scheduled for launch by late 2017. Starting in 2018, the Iridium NEXT constellation will enable Aireon's satellite-based system to provide global aircraft surveillance in real time. Iridium and SpaceX have partnered for a series of seven launches, with ten Iridium NEXT satellites deployed at a time.
• Nov. 10, 2015: The first launch for Iridium’s next-generation mobile communications fleet has been pushed back four months — from December 2015 until April 2016 — to resolve a technical problem inside the spacecraft’s Ka-band communications payload. 19)
- According to Matt Desch, CEO of Iridium, the primary cause of this problem is not that complicated, nor is it difficult to fix. TAS discovered the issue during testing after assembling the component. The specific issue is an RF (radio frequency) spur that occurs at certain temperatures, which could create performance problems in the Ka-band downlinks to Iridium's Earth stations.
- The problem means the first pair of satellites will not ship to their launch site in Russia in November (Dnepr launch), but in March 2016, to begin a 30-day processing campaign leading up to liftoff.
- A “protoflight” version of the Iridium Next spacecraft bus recently completed a thermal-vacuum test at Thales’ facility in Cannes, France, in a final milestone leading to the full flight qualification of the Iridium Next satellites in December, Thales said in a statement.
- TAS (Thales Alenia Space) is leading development of 81 Iridium Next satellites, and Orbital ATK is in charge of spacecraft assembly, integration and testing at a facility in Gilbert, Arizona.
• Oct. 29, 2015: TAS (Thales Alenia Space), prime contractor for the Iridium NEXT constellation, has reached a major milestone in this program with the successful completion of thermal-vacuum tests of the protoflight satellite at the company's plant in Cannes, France. This is the last milestone leading up to the qualification of Iridium NEXT satellites, which is expected to occur in December of this year. 20)
- In parallel, production is proceeding on schedule at the Orbital Sciences facility in Gilbert, Arizona, where ten satellites are currently undergoing assembly, integration and testing (AIT). The last technical issues concerning a critical supplier have now been resolved.
• June 1, 2015: Aireon LLC, developer of the world's first space-based global air traffic surveillance system, announces that Iridium Communications Inc. has completed the first successful integration of the Aireon payload on an Iridium NEXT satellite. This is a key technical milestone toward the first launch of Iridium NEXT and the first demonstration of the Aireon air traffic surveillance capability. 21)
- The forthcoming Aireon service will be deployed using space-based ADS-B (Automatic Dependent Surveillance-Broadcast) receivers built into each of the 66 satellites in Iridium NEXT, Iridium's second-generation satellite constellation. Iridium NEXT is scheduled to launch between 2015 and 2017, with full Aireon service expected to be available in 2018.
- “This milestone moves us significantly closer to being able to provide the global air traffic surveillance system that the world needs,” says Vincent Capezzuto, CTO and Vice President of Engineering, Aireon. “The Aireon system will provide real value to stakeholders by enabling vast improvements in efficiency and safety of air traffic operations. Iridium continues to make good progress with the constellation build, keeping Aireon on track for full service deployment.”
- “The integration of the Aireon hosted payload to the satellite platform is a major milestone for Aireon, Iridium and the aviation industry, in general,” says Matt Desch, CEO, Iridium Communications Inc. “This brings the Iridium NEXT constellation one step closer to hosting the first truly global surveillance and tracking service.”
• Nov. 11, 2014: Iridium reports the successful completion of the verification testing for the new solar panel design of Iridium NEXT. To verify the capabilities of the new design, the solar arrays underwent a rigorous life test and qualification program. This verification procedure allowed the project to test every mechanical and electrical configuration of the solar arrays, while testing them in simulated environments reflecting the harsh conditions into which they will be deployed. 22)
- The solar arrays were also extensively tested for longevity to ensure they would meet and exceed the lifetime expectations of the Iridium NEXT satellites. The solar cells were exposed to 75,000 thermal cycles, each one representing the Iridium NEXT satellite’s movements in and out of the sun’s radiating heat. The testing demonstrated that each array has a lifespan of almost 19 years of in-orbit operations — 6.5 years longer than the expected lifespan on our current satellites.
• September 15, 2014: It’s “All Systems Go!” at Iridium, as the upgrade of the SCS (System Control Segment) and development of the new LEOP (Launch and Early Operations) control center has been completed. To reach this milestone, Iridium has been working closely with our Iridium NEXT Mission Team partners: The Boeing Company and L-3 Telemetry-West, whose InControl™ software suite has been integrated into the SCS. 23)
• In August 2014, Iridium Communications Inc. announced the successful upgrade of its SCS (System Control Segment) and completion of its LEOP (Launch and Early Operations) control center for Iridium NEXT, the largest new commercial satellite constellation in the world. 24)
• In October 2013, Iridium Communications Inc. has successfully completed the CDR (Critical Design Review) of the complete Iridium NEXT satellite network system, demonstrating its design is valid and on schedule for first launch in early 2015. 25)
• In Feb 2011, Iridium Communications announced that Orbital Sciences signed an agreement with Iridium that reserves hosted payload capacity on Iridium's next-generation satellite constellation, Iridium NEXT.
Orbital, as the satellite integrator and test sub-contractor for Iridium NEXT, will also be responsible for the integration of hosted payload platforms with the Iridium NEXT satellites. Orbital's role as the satellite integrator is critical to ensuring that multiple hosted payloads, including Orbital's capacity, can be accommodated simultaneously on the Iridium NEXT constellation. 26)
In 2008, GEO (Group on Earth Observations) — an international intergovernmental initiative with the goal of furthering the creation of a comprehensive, coordinated, and sustained Earth observing system or systems — concluded that four missions stand out as prime candidates for flying on the Iridium NEXT platforms which would also be of benefit for climate observation. These are altimetry, broadband radiometry (Earth’s radiation budget), multispectral imaging (ocean and land) and GPS radio occultation. 96) 97) 98) 99)
There are several additional missions which could provide additional climate/weather observations of interest to various groups. The consensus was that a constellation approach to sensing, using the real-time communications backbone of Iridium, will enable unprecedented geospatial and temporal sampling, with a move from R&D-driven space programs to operational monitoring of the effects of global climate change. 100)
• Earth observation, atmosphere, and climate 101)
- GPSRO (GPS Radio Occultation). One or two instruments can be hosted in each plane (with GPS, GLONASS and Galileo tracking capability) 102)

On March 27-30, 2011, a GEOScan Planning Workshop was held in Annapolis, MD, USA. The dual theme concept of GEOScan involves System Science (SS) sensors on all 66 Iridium NEXT satellites as well as Hosted Sensor (HS) suites that can accommodate unique payloads in a standard, 14 cm x 20 cm x 20 cm [5.6 U] SensorPOD.
Each Iridium NEXT satellite has a total hosted payload allocation of 50 kg in mass, 30 cm x 40 cm x 70 cm in volume, and 50 W of average power. GEOScan was designed to fit into a hosted payload module, which has been allocated 5 kg in mass, 14 cm x 20 cm x 20 cm in volume, and 5 W of average power. In addition to these resources, the Iridium satellite design provides for an unimpeded 75° half-angle nadir FOV (Field of View), nadir pointing control to within 0.35° (pointing knowledge within 0.05°), spacecraft altitude control within 10 m, and spacecraft position control within 15 km (position knowledge within 2.2 km). 103)

ADS-B (Automatic Dependent Surveillance - Broadcast)
Satellite operator Iridium, through its new joint venture Aireon LLC, will be putting ADS-B (Automatic Dependent Surveillance-Broadcast) receivers on its next-generation satellite constellation as hosted payloads, aimed at bringing global, real-time aircraft surveillance for ANSP (Air Navigation Service Providers).
In June 2012, NAV CANADA and Iridium signed a contract for a joint venture to be run under the company Aireon LLC (McLean, VA, USA) with support from the U.S. FAA (Federal Aviation Administration) and suppliers Harris Corporation and ITT Exelis. The objective of Aireon is to take advantage of Iridium's hosted payload services using ADS-B receivers and to deliver a surveillance capability to ANSPs (Air Navigation Service Providers) around the world and their commercial airline customers. 112) 113) 114) 115) 116)
ADS-B is a next generation commercial surveillance technology that supports radar-like separation standards. The system brings significant safety and efficiency benefits, offering properly-equipped and certified aircraft more flexible, fuel-saving routes through airspace previously managed using only procedural air traffic control. Aircraft with ADS-B automatically transmit accurate position reports with integrity every second to ATC (Air Traffic Control). As a result, ADS-B will reduce separation minima for equipped aircraft and allow more aircraft to follow the most efficient flight trajectory.
NAV CANADA corporation owns and operates Canada's civil ANS (Air Navigation Service), providing for the safe and efficient movement of aircraft in Canadian domestic airspace and international airspace assigned to Canadian control. Through its coast-to-coast operations, NAV CANADA provides air traffic control, flight information, weather briefings, aeronautical information, airport advisory services, and electronic aids to navigation. NAV CANADA is the second largest air navigation service in the world by traffic volume and provides air traffic management for 1,200 flights per day, the busiest oceanic airspace in the world. -NAV CANADA will be Aireon's first customer to deploy the new satelliteborne surveillance capability in its North Atlantic airspace operations most of which is without surveillance at the moment.
In November 2012, Iridium Communications Inc. announced that it has finalized an agreement with NAV CANADA regarding Aireon LLC, a joint venture that will allow air traffic management agencies around the globe to continuously track aircraft anywhere in the world. For the first time ever, ANSPs (Air Navigation Service Providers) around the world will be able to track aircraft from pole-to-pole, including oceanic airspace and remote regions. The new capability will provide significant benefits to the aviation industry, including substantial fuel savings, a reduction in greenhouse gas emissions and enhanced safety and efficiency for passengers. 117) 118)
The ADS-B receiver payloads, to be mounted on each Iridium NEXT satellite, will operate independently and perform the air traffic surveillance function separately from the main mission of the spacecraft. The power for the ADS-B payloads will come from the main satellite bus and will be designed to work with the other subsystems, such as thermal management or communications systems. By sharing Iridium's spaceborne capability and ground infrastructure, these commercially hosted payloads illustrate how to avoid the cost of building and launching separate satellites, thereby reducing the expense and time required to put mission capabilities into space for government and private organizations via a public-private partnership model, says a representative. 119) 120) 121)
The spaceborne ADS-B surveillance solution is set up as a joint venture between Iridium and NAV CANADA with support from the U.S. Federal Aviation Administration (FAA) and several other partners:
• Iridium will host the ADS-B receivers on its next-generation Iridium NEXT constellation.
• NAV CANADA is Aireon's first customer and an investor in Aireon. The venture will be operated under a PPP (Public Private Partnership) between industry and the world's major ANSPs.
• Harris Corporation is supplying 81 ADS-B payloads for the venture.
• ITT Exelis is providing systems engineering support.
The Iridium architecture is unique in that all of the satellites are cross-linked, communicating with their neighboring satellites, allowing signals to be relayed from any point on the globe to a central ground location in Tempe, AZ (USA) in near real-time, with back-up locations in Alaska and Norway. The real time nature of relaying ADS-B surveillance data through the Iridium network is critical to achieving radar-like surveillance and reduced oceanic separation minima down to 15 NM (Nautical Miles) for aircraft equipped with appropriate communication and navigation avionics – enabling the full potential of benefits from such operations. No other existing or planned LEO-constellation has an equivalent capability. The Iridium architecture with built in redundancy and backup would provide a seamless experience to the Air Traffic Controllers when utilizing the Aireon surveillance capability. 122)
The Iridium NEXT LEO constellation is the world's largest with 66 operational satellites, plus six on orbit and nine ground spares, providing a level of redundancy and system availability that is unprecedented. The Iridium satellite design has significant built-in redundancy and high reliability. The planned ADS-B payload receivers will have even higher reliability requirements and the design will include the ability to make on-orbit software updates to adapt to future changes in ADS-B formats, if required. No other LEO constellation has a comparable global coverage, system availability, redundancy or flexibility.
The Aireon global space-based ADS-B surveillance system is being developed under a joint venture between Aireon and NAV CANADA and will be operational in 2017. This transformational new global surveillance system will offer far reaching capabilities and benefits to the global aviation community. The global aviation community would benefit by early interaction and participation in the development and deployment of this capability.
Background: In the timeframe 2010, ADS-B is a land-based system and deployed primarily in high air traffic areas such as North America, Australia and Europe. Vital airways over oceans, mountains, remote areas and polar regions remain largely uncovered.
In the ground-based ADS-B system concept, each aircraft broadcasts its own GPS position along with other information like heading, ground track, ground speed, altitude. Receivers on the ground then receive this information and send it to air traffic control displays. The ADS-B information can be used to augment existing primary and secondary (transponder-based) radar or used in lieu of those radar technologies. Aircraft that broadcast this information are considered to be equipped with ADS-B Out. ADS-B is all about communications between aircraft, and also between aircraft and ground. Both are vital in ensuring safe flights and efficiency in terms of fuel use, time and emissions. ADS-B is an integral part of the planned efficiency drive towards 2020. 123) 124)
Taking advantage of the latest technology, ADS-B is designed to be retrofit on aircraft flying today. In its final form, ADS-B is designed to ease ATC (Air Traffic Control) as the number of approaches grows, enhancing safety and increasing airport capacity. In the air, the information provided by ADS-B enhances the pilots' traffic awareness, allowing more optimal flight levels leading to fuel savings. ADS-B is designed in two parts:
• ADS-B OUT provides a means of automated aircraft parameter transmission be tween the aircraft and the ATC.
• ADS-B IN provides automated aircraft parameter transmission between aircraft themselves.
Ground-based systems primarily use radar to provide aircraft surveillance. As part of the global ATM modernization, ANSPs (Air Navigation Service Providers), such as the U.S. Federal Aviation Administration (FAA) and NAV CANADA, are implementing new ADS-B systems. On-board ADS-B transmitters broadcast GPS position and other useful data; yet, ADS-B networks are limited by ground-based ADS-B towers, which collect this data for the ANSPs. The ground-based ATM infrastructure cannot monitor flights over oceans or remote regions of the globe where placing an ADS-B tower is not feasible, adds the representative.
ADS-B Mission Status
• July 25, 2019: Aireon LLC announced today that The Airports Authority of India (AAI) has signed a contract to implement Aireon's air traffic surveillance service in Mumbai, Chennai and Kolkata's oceanic airspaces. These regions are located in the Arabian Sea, Bay of Bengal and Indian Ocean and represent over six million square kilometers. The goal is to deploy spaceborne Automatic Dependent Surveillance-Broadcast (ADS-B) by the end of 2019. 125)
- This landmark agreement will immediately provide AAI coverage of all ADS-B OUT 1090 MHz equipped oceanic air traffic, ensuring one of the densest oceanic airspaces in the world has access to the best tools to enhance safety and efficiency and accommodate unprecedented double-digit growth, year over year. Beyond those benefits, real-time air traffic surveillance over the busy routes between South East Asia, India, the Middle East and Europe and beyond will significantly increase efficiency and improve transitions between oceanic and domestic airspace.
- "The decision to implement Aireon's technology is not only a major step in improving safety and enhancing capacity for our flying public, but also ensures that as one of the globe's fastest growing markets, we are planning for our continued growth," said Dr. Guruprasad Mohapatra, Chairman, AAI. "AAI will be the first Air Navigation Service Provider in the region to implement a technological initiative, on this scale, and offer enhanced air traffic surveillance services to its users."
- India has become the third largest aviation market in the world with a rate of sustained double-digit growth for the last 50 months. Forecasts suggest that the growth will continue, and Indian airspace is going to experience an imminent need for additional capacity.
- "AAI's leadership and approach to technology and safety is ensuring that one of the world's busiest airspaces continues to be one of the safest," said Aireon's CEO, Don Thoma. "We are excited that AAI will be the first in the region to deploy this capability and we look forward to this partnership to improve safety and efficiency in Indian airspace."
- The AAI contract signing comes three months after the Aireon service went live on April 2,2019. With AAI moving forward with full implementation of space-based ADS-B, set for year's end, AAI will ensure India meets its growing capacity demand with the controller tools needed to provide the highest safety standards to its flying public. India will join 26 other countries who are actively deploying Aireon's space-based ADS-B for air traffic surveillance.
• July 9, 2019: The aviation industry's first-ever public global aircraft emergency locating service, Aireon ALERT (Aircraft Locating and Emergency Response Tracking), has begun live operations out of Ireland's Ballygirreen communications base. 126)
- Aireon ALERT provides registered aircraft operators, aviation regulators and search-and-rescue organizations with the last known position of ADS-B equipped aircraft to help reduce accident search areas and keep controllers and dispatchers updated on flights experiencing distress. Aireon opened the pre-registration period for the service in August 2018, and now has more than 193 airlines, air navigation service providers (ANSPs) and search-and-rescue agencies using it.
- IAA (Irish Aviation Authority) and Aireon are providing the service free of charge, in an effort to help prevent MH370-style incidents from occurring where aircraft operating in remote areas lacking terrestrial radar are unable to be tracked. In the event of an emergency, registered users can contact IAA with a flight ID or 24-bit ICAO address and receive four-dimensional report including the last 15-minutes of ADS-B tracking information for the flight they're inquiring about verbally and through email.
- Users also instantly receive two graphical depictions of the aircraft's flight path. One gives aircraft position relative to global airspace, while the other depicts its position within the specific flight information region it is operating in.
- Sean Patrick, general manager of oceanic services at IAA, said ALERT operators also assign the queried aircraft a KML file that can be plugged into Google earth to depict a graphical representation of the aircraft's flight path and last known position report. IAA is operating the service 24 hours a day.
- "You're talking about a position report to within meters," Patrick said, during a press conference announcing the go-live status of Aireon ALERT.
- IAA, which is also an investor in Aireon, volunteered to provide staff to operate the free service to registered users as part of the broader space-based ADS-B surveillance service which officially went live in April. The ANSP's air traffic control centers already monitor up to 1,700 flights per day between North America and Europe, and 950,000 aircraft movements per year.
- Patrick said the service is geared toward commercial airlines, but is open to operators across all segments.
- "The business aviation community are more than welcomed to operate this service, it is catered toward the commercial end of the market," Patrick said. "What we don't want is the smaller aircraft, the GA type aircraft to utilize the service, simply because we don't have the capabilities of answering all the queries that we would get, but if there is an issue with a GA-type aircraft that can be escalated through the normal circles."
- IAA, in coordination with NATS UK, and NAV Canada are conducting ongoing systems and data validation of Aireon's global space-based ADS-B surveillance service in the North Atlantic airspace with full operational service planned for November 2020. Thus far, 11 ANSPs are commercial space-based ADS-B surveillance customers.
• June 4, 2019: Aireon was officially approved by the European Union Aviation Safety Agency (EASA) as an Air Navigation Service Provider (ANSP) Organization to provide Air Traffic Management (ATM)/Air Navigation Service (ANS) surveillance services, to support the separation of aircraft. This authorizes Aireon as the first-ever certified provider of aircraft surveillance-as-a-service. 127)
- This designation represents the culmination of a three-year long collaboration between Aireon and EASA, the agency that determines and promotes civil aviation safety standards for the member States of the European Union (EU) and other associated States. EASA's rigorous and holistic certification process ensured the performance of the Aireon data for use in critical safety-of-life Air Traffic Services (ATS) surveillance.
- Aireon is committed to the safe delivery of space-based Automatic Dependent Surveillance-Broadcast (ADS-B) services to its customers Air Traffic Control (ATC) systems. By recognizing the performance of Aireon's ADS-B service, this EASA certification is a major milestone to legitimize the world's first set of global real-time air traffic data.
- According to Manfred Dieroff, EASA's ATM/ANS Standards, Implementation and Oversight Section Manager, "EASA performed a series of audits that addressed the compliance with the EU Regulation applicable to ATM/ANS Surveillance services, including among others management processes, system development and verification, software assurance, operational processes, service monitoring and technical support. With this certification, Aireon is able to provide its customers with an EASA accepted Service Definition Document and Safety Case accepted by EASA in the frame of the initial certification."
- "This is not only a validation of our processes, procedures and safety-case in the EU, but it also establishes a robust safety case that can be used outside of the EU and throughout the world," said Vincent Capezzuto, Aireon's CTO and Vice President of Engineering.
- As the EU's preeminent civil aviation regulatory authority, today's certification ensures that Aireon will not undergo additional certifications for business purposes in Europe, providing a significant opportunity to expand safety, environmental and business benefits of Aireon's space-based ADS-B data.
- "EASA's certification, the first of its kind for a provider like Aireon, is just the beginning," continued Capezzuto. "This is an absolute differentiator for Aireon as a global provider of surveillance-as-a-service."
- "The incredible team at Aireon is dedicated to improving safety across the entire aviation community, continued Dieroff. "We look forward to our future interactions and continuous oversight."
• April 2, 2019: Effective today, Aireon, the first ever realtime, global air traffic surveillance system, is fully operational and in trial use over the North Atlantic. This announcement marks a historic milestone for the aviation industry— ushering in a new era of safety and efficiency that will revolutionize the way people fly. 128)
- Aireon's space-based Automatic Dependent Surveillance Broadcast (ADS-B) system provides real-time air traffic surveillance and tracking to 100 percent of ADS-B equipped aircraft on the planet. Prior to Aireon's system coming on-line, traditional ground-based surveillance covered just 30 percent of the globe, meaning civil aviation authorities, commercial carriers and related industry stakeholders relied upon position updates from aircraft every 10-14 minutes to track aircraft outside of radar coverage, not the realtime updates that the Aireon service provides.
- "For the first time in history, we can surveil all ADS-B-equipped aircraft anywhere on earth," said Don Thoma, Aireon CEO. "Our air transportation system has operated with a safe but less than efficient system in the 70 percent of the world that does not have real-time surveillance. With the launch of our space-based ADS-B service, Aireon now provides a real-time solution to that challenge—one that will radically optimize flight safety and efficiency. The aviation industry has now joined the rest of the 21st century where real-time connectivity is relied upon for doing business."
- The Aireon system is expected to reduce overall flight safety risks by approximately 76 percent in the North Atlantic according to a joint analysis by NAV CANADA and NATS – the first Air Navigation Service Providers (ANSPs) to use the service. Improved visibility and control over previously un-surveilled airspace—especially across oceanic regions—will allow airlines to fly routes at optimal speeds and levels, delivering expected cost savings of up to US$300 per transatlantic flight, plus reducing carbon dioxide emissions by two tonnes per flight, based on an analysis conducted by NATS and the ICAO (International Civil Aviation Organization).
- Use of the Aireon system over the Atlantic allows for air traffic controllers to trial the reduction of aircraft in-trail separation distances from 40 nautical miles (nm) to just as little as 14nm, making the airspace more flexible, predictable and able to accommodate the immense growth predicted in the coming years.
- "To know the position, speed and altitude of every ADS-B equipped aircraft in oceanic airspace – in realtime – is a transformational change to how our controllers manage air traffic," said Neil Wilson, president and CEO of NAV CANADA. "The Aireon system provides an immediate boost to aviation safety and airlines will benefit from more fuel-efficient routings and flight levels. Over 95 percent of the North Atlantic traffic is already ADS-B equipped so the fuel savings, along with the reduced carbon dioxide emissions will be attained very quickly."
- Regulations mandating ADS-B equipage on aircraft have already been implemented throughout the world, going into effect in the United States in January 2020 and in Europe in June 2020. Other countries are in the process of drafting mandates for implementation over the next few years.
- Martin Rolfe, NATS CEO, said, "The trial in the North Atlantic, the busiest oceanic airspace in the world, with over 500,000 flights every year and a forecasted 800,000 flights per year by 2030, will demonstrate to the entire aviation industry, that global, space-based ADS-B can revolutionize the service that we provide to our customers and the travelling public by transforming the way we perform air traffic management over remote regions."
- Eight years in the making, Aireon's ADS-B payloads are hosted on the Iridium® NEXT satellite constellation—the final deployment of which took place January 11, 2019. After receiving control of the final six ADS-B payloads from Iridium on February 7, 2019, Aireon completed payload testing, validation and calibration stages prior to launching the full system into operation to support current ANSP customers.
- "Improved safety and cost savings for all aviation stakeholders is just a start. The revolutionary impact of the real-time location data and historical tracking information of Aireon's space-based ADS-B data will create innovations that we have not even imagined. The opportunities for comprehensive and continuous benefits for the whole aviation community are at our fingertips. We would not be able to achieve this without our dedicated investors, NAV CANADA, Iridium Communications, NATS, Enav, The Irish Aviation Authority (IAA) and Naviair, and our partners and launch customers. This is a great day for us all," Thoma concluded.
• January 14, 2019: Aireon's space-based ADS-B (Automatic Dependent Surveillance-Broadcast) payload was successfully deployed during the eighth and final launch and positioning of the Iridium NEXT satellite constellation on 11 January , a SpaceX Falcon 9 rocket lifted off from Vandenberg Air Force Base in California and placed the final 10 Iridium NEXT satellites into LEO. 129) 130)
- This launch brought the total number of Aireon payloads in orbit to 75 (66 operational payloads and 9 spares), completing the historic launch program and passing one of the last remaining milestones before Aireon ushers in a new era of global air traffic surveillance and aircraft tracking.
- Aireon is the world's first 100 percent global air traffic surveillance system and is revolutionizing the way the world travels with space-based technology. Unlike existing aircraft surveillance and tracking infrastructure, the Aireon system uses space-based ADS-B technology, which enables the automatic and real-time collection of aircraft position data. The Aireon technology gives air traffic controllers and airlines a complete and comprehensive view of the entire sky, like never before. With this upgraded insight into the world's flight paths, including those in remote and oceanic airspace, the entire industry will experience significant direct and indirect benefits such as, increased safety, more efficient flight routes, more accurate arrival and departure predictions, faster emergency response times, reduced aircraft separation, a decrease in CO2 emissions and more.
- Thus far, the Aireon system has out-performed all predictions and is processing more than 13 billion ADS-B messages per month, with that number expected to grow upon full deployment. Air traffic controllers rely on the best and most accurate surveillance data possible to separate aircraft, which is often achieved through multiple redundant layers. Aireon's data will provide air traffic controllers with a fully redundant data feed that covers the entire airspace, increasing the availability and reliability of a critical component in air traffic management, with a positive impact on safety and efficiency. This will in turn, help improve flight optimization by eliminating gaps in fleet data reports, and ultimately enhance the overall safety, accuracy and efficiency of worldwide air travel.
- This launch marks the completion of the Iridium NEXT launch campaign, successfully deploying the full Aireon system.
- Don Thoma, the CEO of Aireon, said that the company has passed a major milestone on the firms journey to revolutionize air traffic surveillance and the company is just weeks away from a fully operational system. Now that the launches are complete, final integration and testing of the recently launched payloads can commence, after which the world's first, real-time, truly global view of air traffic will be a reality. It's difficult to contain the excitement until all is formally operational, especially as from a performance standpoint, the company's technology has far exceeded expectations. Many may think this is the end of a journey, being the last Iridium NEXT launch; however, for Aireon, this is the start of a new way air traffic will be managed.
- Marion Blakey, former Administrator at the Federal Aviation Administration (FAA), added that Aireon's space-based ADS-B network is just what the aviation industry needs. During my time at the FAA, extensive work was done to promote ADS-B technology for global air traffic management efforts. Today's successful launch is a victory for Aireon as well as for the aviation industry — one step closer to having a clear, accurate and complete picture of the world's airspace, including over the oceans and remote areas.
- A total of 81 Iridium NEXT satellites have been built, all of which have the Aireon payload onboard. There are now 75 satellites deployed, with nine serving as on-orbit spares and the remaining six as ground spares. Today's launch marks the completion of the Iridium NEXT launch campaign, successfully deploying the full Aireon system.
• May 16, 2018: The UK air traffic management service provider, NATS (National Air Traffic Services) and part of the UK CAA (Civil Aviation Authority), has announced it has invested in Aireon, the company pioneering a space-based air traffic surveillance service set to revolutionize the aviation industry. 132)
- Through a network of 66 LEO (Low Earth Orbiting) Iridium® NEXT satellites, AireonSM will monitor the location of ADS-B (Automatic Dependent Surveillance-Broadcast) equipped aircraft flying anywhere in the world, transforming the way air traffic control services are provided.
- The service will offer global air traffic surveillance of aircraft. This means that oceans and remote regions like the poles, deserts and mountainous areas will have real-time aircraft surveillance for the first time.
- The forecasted safety and airspace capacity benefits, together with the savings in fuel and carbon emissions, are being hailed as the greatest revolution in air traffic management since the introduction of radar 70 years ago.
- News of the $69 million USD investment, worth around 10% equity, was announced at a press conference in Washington DC, near Aireon's headquarters, at which NATS also confirmed it is currently consulting with its customers about introducing the satellite technology for use over the North Atlantic starting with operational trials from 2019 to deliver the capacity and safety benefits that the airspace requires to keep pace with demand.
• April 2, 2018: Aireon's fifth successful launch and the deployment of the company's space-based Automatic Dependent Surveillance-Broadcast (ADS-B) payloads, hosted by the Iridium® NEXT satellite constellation, succeeded at 14:13:51 UTC, as a flight-proven SpaceX Falcon 9 rocket lifted off from Vandenberg Air Force Base in California — this brings the total number of Aireon payloads on orbit to 50. 133)
- When the Aireon payloads from the fifth launch come online, the system will have nearly global coverage with 15-minute or better update intervals. This signifies optimal timing for airlines to begin testing the capabilities of space-based ADS-B. This will assist airlines with meeting the International Civil Aviation Organization (ICAO) and European Aviation Safety Agency (EASA) regulations that require aircraft be equipped with an aircraft tracking system for those flights not tracked by air traffic control by the end of 2018. With the Aireon service and access to the space-based ADS-B data, airlines can meet this directive set by regulators and safety organizations.
- FlightAware and Aireon have worked together to create GlobalBeacon, a first-of-its-kind product. GlobalBeacon combines FlightAware's data processing platform and web-interface with Aireon's space-based ADS-B data for a cost-effective, easy to deploy solution to help meet the ICAO Global Aeronautical Distress Safety System (GADSS) standards.
- The Aireon system is hosted on the Iridium NEXT satellite constellation. A total of 81 Iridium NEXT satellites are being built, a ll of which will have the Aireon payload onboard. Currently, 75 satellites are planned to be deployed, with nine serving as on orbit spares and the remaining six as ground spares. The constellation is planned for completion during 2018. In addition to GlobalBeacon, FlightAware is delivering the data through services that are already commonly used by airlines and industry leading service providers, such as SITAONAIR.
- Don Thoma, the CEO of Aireon, said that the company is more than two-thirds of the way there. And as Aireon gets closer to a fully operational system, thorough testing and validation is now underway with customers and partners. Aireon is working closely with ANSPs and partners such as FlightAware to ensure airlines have early access to this global data, ahead of regulations and requirements. Aireon will be able to help airlines meet these mandates, and upon completion of the constellation, update rates of a few seconds will be the service standard around the world.
- Dominique El Bez, Vice President, Product and Strategy, SITAONAIR, added that the firm's partnership with FlightAware means that any airline using AIRCOM® FlightTracker will have at its fingertips a dynamic tool providing an overview of the exact position, speed and altitude of its airborne fleet. Most critically, the coverage will now be 100 percent,even over oceanic, remote and polar areas. By receiving once-per-minute positions from Aireon's network of space-based ADS-B receivers, airlines will exceed the ICAO GADSS upcoming 15-minute recommendation.
• May 3, 2017: Aireon announced that NAV CANADA has completed a successful flight test of spaceborne ADS-B (Automatic Dependent Surveillance-Broadcast) technology. The test was conducted to collect ADS-B data used for validating Aireon's satellite aircraft surveillance and tracking service. The NAV CANADA flight occurred on March 7, 2017 and utilized a specially equipped Bombardier aircraft with both top and bottom mounted 125 W ADS-B antennas. It was the first of two scheduled flight tests by the Canadian ANSP (Air Navigation Service Provider). Additional flight tests were done by the FAA (Federal Aviation Administration) and Polaris Flight Systems. 134)
- During the flight test, 6,935 ADS-B messages were received and decoded by a single Aireon payload, and after rigorous analysis, were found to exhibit comparable results to that of terrestrial ADS-B stations. Traveling through the Montreal, Winnipeg and Edmonton FIRs (Flight Information Regions), the flight test was a highly choreographed exercise requiring the aircraft to position itself in the correct airspace while the appropriate Iridium NEXT satellite carrying the Aireon ADS-B receiver was overhead.
- An additional flight test with the FAA took place on March 30, 2017, utilizing the FAA's specially equipped "flying laboratory" Bombardier jet with three Aireon payloads available to receive data. A total of 2,462 ADS-B messages were received and decoded while also exhibiting comparable results to that of terrestrial ADS-B stations. The FAA flight test took place in the Washington and New York FIRs.
- Aireon also conducted a flight test with Polaris Flight Systems, a private vendor, on March 20, 2017. The aircraft, a Beechcraft Bonanza, was outfitted with a top and bottom mounted 200 W ADS-B antenna and flew solely through the Albuquerque FIR, where more than 1,050 ADS-B messages were received from two Aireon payloads during the flight.
- "The flight tests coordinated with NAV CANADA, the FAA, and Polaris Flight Systems have been remarkable successes and further enable our team to thoroughly validate the capabilities of our system," said Vinny Capezzuto, chief technology officer and vice president, engineering at Aireon. "Through multiple flight information regions, with various levels of aircraft traffic, these tests were able to put our system through some challenging environments, and the data we've received is incredibly strong."
- "NAV CANADA is excited to play such an important role in helping to bring the next-generation of air traffic surveillance and aircraft tracking to the world," said Rudy Kellar, executive vice president, service delivery at NAV CANADA. "Aireon will fundamentally change the way the world flies, increasing safety, efficiency and reducing greenhouse gas emissions. The benefits will find their way right down to the individual traveler who will benefit from more predictable flight times and more efficient airport ground operations."
- Aireon's spaceborne ADS-B system will be operational in 2018, providing ANSPs with global air traffic surveillance and airlines with real-time flight tracking. The first ten Iridium NEXT satellites carrying the Aireon hosted-payloads were launched into low-Earth-orbit from Vandenberg Air Force Base on a SpaceX Falcon 9 rocket on January 14, 2017. Seven additional SpaceX launches are scheduled to take place over the next 12 to 15 months, including the second launch targeted for June of 2017. In total, the operational constellation will consist of 66 satellites, with an additional nine serving as on-orbit spares.
• March 2, 2017: Aireon announced today that they have formally received control from Iridium Communications Inc. of the first ADS-B (Automatic Dependent Surveillance-Broadcast) payload hosted on an Iridium NEXT satellite. This is a major milestone on the path towards 100 percent global air traffic surveillance. Aireon now begins a rigorous, in-depth testing and validation process, verifying the capability of the ADS-B payloads. 135)
- Known as an IPV (Initial Performance Verification), this process will last approximately two weeks before transitioning to a DPV (Detailed Performance Verification) that will focus more specifically on calibrating the payloads for optimal performance. Procedures for the IPV were under development for over a year with valuable insight provided by Iridium, Harris Corporation, NAV CANADA and the Federal Aviation Administration.
- "When we first turned on the payloads after they reached orbit, we received an unexpected surprise – aircraft were immediately being seen in real-time," said Aireon CEO, Don Thoma. "We've already seen commercial aircraft, general aviation aircraft and helicopters, in oceanic and remote airspace that have never before had real-time surveillance. The real fun for us now begins as we take control and push the performance to see just what spaceborne ADS-B can do."
- In late January, the first "power-on" for the AireonSM ADS-B payload was performed to validate launch survival and run a self-diagnostic systems check. During this systems check, Aireon did not expect to see any aircraft, however the payload antennas were active and 150 ADS-B aircraft were detected over multiple-passes with thousands of ADS-B messages received and decoded. Among some of the firsts for the Aireon system are:
a) The first officially received ADS-B message was Korean Airlines 530
b) The first full ADS-B position message decode was SAS 4576
c) The first U.S. carrier ADS-B message was UA 86 to Shanghai
d) The first aircraft detected landing at an airport was NextJet 594 in Sweden.
- "Detecting NextJet 594 was an added bonus," said Vincent Capezzuto, CTO for Aireon. "This is an early proof-point of the power of the Aireon ADS-B payload and its ability to detect aircraft close to the ground and in terminal airspace."
Global AIS (Automatic Identification System)
Realtime Services provided by COM DEV and Harris Corporation
Harris Corporation and exactEarth Ltd., a subsidiary of COM DEV, have formed a strategic alliance to offer new advanced data services that will help track maritime vessels faster and more accurately than ever before. The AIS (Automatic Identification System) services will, for the first time, provide constant, realtime, global coverage — enabling customers to reliably track the location of vessels anywhere in the world. This helps improve efficiency, safety and security. 136)
The services take advantage of exactEarth's proven and patented signal de-collision detection technology and Harris' expertise in satellite hosted payloads, advanced radio frequency communications, and satellite antenna solutions. ExactEarth Ltd. is a majority-owned subsidiary of COM DEV International. The services are made possible by a sensor that is based on Harris' AppSTAR™ reconfigurable payload technology and hosted on the Iridium NEXT satellite constellation — which will have 66 satellites to greatly expand global maritime traffic coverage versus the eight satellites used today.
New AIS-based data products and services are expected to be available in 2018, once the Iridium NEXT satellites are on orbit. Harris becomes the exclusive provider to the U.S. government of AIS products and services produced under the alliance, including exactEarth's exactAIS product portfolio, while exactEarth serves all other global markets.

This new satellite AIS architecture encompasses the complete maritime domain with realtime, continuous satellite coverage. The satellites are networked together with crosslinks and constantly communicate with multiple ground stations, customers receive AIS data in real time. 140)
AIS Mission Status
• June 26, 2017: Adding to the excitement of our recent news that the first four real-time satellites were brought into service, nine more satellites were just launched into the revolutionary constellation, exactView RT powered by Harris. 141)
- The June 25 Iridium NEXT launch successfully carried nine of our real-time payloads into orbit where they are now undergoing standard commissioning and are expected to be brought online in the coming months. With this recent launch, exactEarth now has the most number of AIS receivers in orbit.
- By the end of 2017 more than half of the exactEarth RT powered by Harris payloads are expected to be in orbit with the rest following quickly to meet our 2018 completion date. The future is near!
• On May 30, 2017, exactEarth Ltd. announced the launch of exactView™ RT powered by Harris, the world's first global, persistent real-time Satellite AIS service. exactView RT consists of a system of more than 60 maritime satellite payloads, designed, built and operated by Harris Corporation – a world leader in satellite payload technology - which are hosted onboard the Iridium NEXT constellation of satellites. These advanced maritime payloads cover the entire maritime VHF radio band and leverage the unique cross-linked architecture of the global Iridium NEXT satellite constellation to deliver AIS and other vessel-based VHF data services from any vessel, anywhere on the globe, relaying that data securely to customers in real-time. Today the first four of these advanced real-time maritime payloads are being put into service with the completion of full system deployment expected in 2018. 142)
- Initially, the system is tracking more than 250,000 AIS-equipped vessels around the world including Class B AIS device transmissions utilizing exactTraxTM technology. With the continued growth of the highly successful global AIS system, this tracked population is expected to grow to more than one million vessels worldwide in the next decade. Real-time global AIS data unlocks huge possibilities and enables significant advances in maritime safety, security and efficiency. Advantages include the ability to provide automatic alerts when vessels veer off course; real-time route optimization can provide substantial fuel savings and emissions reductions for vessel owners and operators; logistics and port operations will run more efficiently with highly accurate location and arrival predictions; and, fishing activity can be more effectively managed and enforced.
