The FAA manages the largest airspace in the world with responsibility for more than 24,600,000 square miles of oceanic airspace. As such, the FAA needed to play an important role in the development and deployment of space-based ADS-B. The FAA was one of the first ANSPs to partner with Aireon to explore using space-based ADS-B and entered into a MOA in 2011. The FAA has engaged in the requirements development and the design process of the Aireon system from its inception, in order to influence critical safety and security requirements and to ensure Aireon built a robust surveillance system.
Aireon was created in 2012 to provide real-time global air traffic surveillance anywhere in the world. Aireon’s service will use space-qualified Automatic Dependent Surveillance-Broadcast (ADS-B) receivers built into each of the 66 satellites in Iridium NEXT, Iridium’s second-generation satellite constellation, to deliver this transformational capability.
Aireon signed a 17-year, $42 million agreement with ITT Exelis (now Harris) to provide the ADS-B data processing and distribution component of the Aireon℠ system. Under the terms of the contract, Harris designed and built the processing and distribution platform, a critical component of the Aireon system, and will operate and maintain the system for 15 years.
Harris will provide 81 ADS-B 1090 Extended Squitter receiver payloads to Aireon. The Harris contract represents the largest implementation of a hosted payload solution to date. ADS-B receiver payloads will be mounted on each Iridium NEXT satellite to operate independently and perform the air traffic surveillance function separately from the main mission of the spacecraft. ADS-B payload power will come from the main satellite bus and it will be designed to work with other sub-systems such as thermal management or communications systems.
NAV CANADA agreed to make a total investment in Aireon of up to $150 million. This investment will be made in five tranches, each subject to the satisfaction of various operational, commercial, regulatory and financial conditions. Payment for the first tranche — amounting to $15 million and representing 5.1 percent of the fully diluted equity of Aireon — was made on November 19, 2012. The final tranche is scheduled for late 2017, and NAV CANADA’s preferred membership interest could ultimately represent up to 51 percent of the filly diluted equity of Aireon.
The investment in Aireon by ENAV, the Irish Aviation Authority and Naviair will be made in four tranches between 2014 and 2017 as key milestones are met. The financing comes on top of the investments already made by the current joint venture participants, NAV CANADA and Iridium Communications Inc. In 2018, a portion of Iridium’s interest will be redeemed for a payment from Aireon of $120 million to finalize the ownership interests. Upon this redemption, NAV CANADA will hold 51 percent of the fully diluted ownership of Aireon, Enav will hold 12.5 percent, and each of IAA and Naviair will hold 6 percent ownership, with 24.5 percent being retained by Iridium.
The ADS-B payload successfully completed qualification testing for operation in the harsh environment of space. This achievement is a key building block in the deployment of AireonSM and represents a significant milestone in validating that the payload and system design will provide robust reception of ADS-B signals from space.
NATS, the U.K.’s privatized provider of air traffic control services, has signed a 12-year agreement with Aireon to deploy space-based ADS-B. NATS is a charter ANSP of Aireon, working closely with NAV CANADA and the FAA on the technical and operational development of space-based ADS-B services. In this capacity, the three organizations will work on the development of common requirements for the service, including the development of policies, standards and operational procedures.
Aireon 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 Aircraft Locating and Emergency Response Tracking (ALERT) service will allow aviation stakeholders to track any aircraft that is in an apparent alert or distress phase providing them with precise GPS-based location updates in real-time.
Aireon signed a data services agreement with the Civil Aviation Authority of Singapore (CAAS) to provide space-based ADS-B data for the Singapore FIR. Singapore will be the first ANSP in the Asia Pacific region to adopt space-based ADS-B.
Aireon signed a data services agreement with Air Traffic and Navigation Services (ATNS), South Africa’s ANSP. ATNS has decided to implement space-based ADS-B to enable real-time visibility throughout their airspace. Increased visibility, coupled with real-time air traffic surveillance, improves both the safety and efficiency of air travel and gives air traffic control the ability to optimize airspace with more accurate, predicable data.
The International Telecommunication Union (ITU) granted primary allocation of the 1090 MHz frequency band for the reception by satellite of ADS-B signals from aircraft. The decision, made during the World Radiocommunication Conference (WRC-15) in Geneva, Switzerland, protects this essential frequency for real-time flight tracking and global surveillance of aircraft through ADS-B over satellite. This important step will extend air traffic surveillance coverage of equipped aircraft to 100 percent of the earth’s surface – from the 30 percent coverage available today.
Aireon signed a data services agreement with the Dutch Caribbean Air Navigation Service Provider (DC-ANSP), the air traffic services provider for the Curaçao Flight Information Region (FIR). This agreement represents a milestone for the Latin American and Caribbean regions, positioning DC-ANSP as a regional leader in aviation safety and efficiency. This will also allow DC-ANSP to increase flexibility over the cross-regional and intersecting routes they manage and facilitate seamless transitions between neighboring FIRs.
ATNS signed a commercialization agreement with Aireon to establish a framework for facilitating the use of space-based ADS-B in the Southern African Development Community (SADC) region. The Agreement will leverage ATNS’s leadership role in the SADC as the operator of the regional VSAT network to distribute space-based ADS-B data to remote locations over satellite links, thereby extending the surveillance capabilities to regions where ground-based communications are prohibitive.
This milestone validated Aireon’s end-to-end performance in preparation for on-orbit tests. Aireon ground systems including the Hosted Payload Operation Center (HPOC) and the Aireon Processing and Distribution Center (APD) functionality is verified. Validations also included the ability to command, status and control the payload, and that the APD will perform real-time control of the payload to receive transmissions from ADS-B equipped aircraft. Transmissions received by the payload are routed through Iridium to the HPOC, APD and delivered to NAV CANADA for final verification.
Harris completed production on all ADS-B payloads. The 81 ADS-B payloads were completed ahead of schedule and represent the largest implementation of a hosted payload solution ever achieved. Completion of these payloads represents another milestone toward deploying Aireon’s space-based ADS-B service and enabling real-time air traffic surveillance worldwide.
Aireon signed a contract with the Seychelles Civil Aviation Authority (SCAA), the air traffic services provider in the Seychelles Flight Information Region.
