In 2018, Aireon will deploy the world’s first truly global air traffic surveillance system, extending ADS-B across the entire planet. Through an unprecedented space-based ADS-B system, Aireon will provide 100 percent surveillance coverage of ADS-B equipped aircraft in real time.
Space-based ADS-B will be a turn-key surveillance solution, delivering traditional ADS-B messages directly to the Air Navigation Service Provider (ANSP) like traditional ADS-B radio would do. The major difference is that the Aireon delivery point will provide a single source for all 1090ES aircraft for the entire FIR and beyond.
Space-based ADS-B will eliminate global blind spots, allow for increased safety, precise aircraft locations, improved search and rescue response, reduction in gross navigation errors, enhanced cross-border safety and faster pilot/controller communication.
This reference guide gives high-level overviews of the history of air traffic surveillance, how aircraft position is currently determined, ADS-B history, the challenges of current global surveillance and how Aireon series will transform air traffic surveillance.
GlobalBeacon, a first of its kind product from Aireon and FlightAware, will detect your aircraft’s position in real-time, everywhere in the world. It's s an easy-to-deploy solution to help airlines become compliant with International Civil Aviation Organization (ICAO) Global Aeronautical Distress Safety System (GADSS) standards
Aireon Aircraft Locating and Emergency Response Tracking (ALERT) 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 1090MHz equipped aircraft’s most recently known position.
The Aireon system has been designed to address the safety, efficiency, availability and performance requirements that have been mandated by many air traffic organizations worldwide. Take a look at the technical details of the overall system and how the receivers will function when the constellation is fully-operational in 2018.
This technical chart details the four main transition scenarios where Aireon will deliver substantial benefits to stakeholders.
Space-based ADS-B will extend this critical NextGen air traffic surveillance beyond the reach of traditional ground stations and will provide real-time coverage for not only 100 percent of U.S. managed airspace, but for the first time, 100 percent of the globe. Expanding ADS-B coverage through a space-based system will significantly increase the benefits in efficiency and safety to all stakeholders, while requiring no additional avionics beyond what is already mandated by the FAA in 2020.
Following the implementation of the European ADS-B mandate in June 2020, space-based ADS-B will be utilised by the IAA to rationalise radar infrastructure, with a layer of terrestrial surveillance, supported by space-based ADS-B, thus significantly reducing the cost of providing air traffic surveillance in Irish airspace.
Once space-based ADS-B is operational, ATNS can distribute the data through the region on the existing Southern African Development Community (SADC) and NAFISAT (VSAT-based connection among Southern African ANSPs) networks, from where the data could be merged with the legacy, ground-based surveillance and air traffic management systems. ATNS (and other ANSPs) can apply the data either as an independent autonomous or complementary contributing or redundant source of surveillance, to mitigate issues that may arise with existing ground based surveillance systems such as ground-based ADS-B sensors, rotating radars and telecommunications lines.
Aireon’s space-based ADS-B service will be completely independent from Naviair’s current air traffic surveillance infrastructure. It will add a layer of redundancy to Naviair’s surveillance capability that does not exist today. Space-based ADS-B will be utilized in contingency situations where either critical resources in the current system are completely or partially missing or when the data from current sources is malfunctioning.
When Aireon’s space-based ADS-B service is operational in 2018, the Civil Aviation Authority of Singapore (CAAS) will integrate the data with those from the existing surveillance sensors. The space-based ADS-B data will serve as an independent and separate source of surveillance data over the Singapore FIR, to complement the existing data.
NAV CANADA plans on implementing Aireon initially in its North Atlantic operations. Using the real-time surveillance data and the current communication capabilities in the North Atlantic, the initial goal is to apply 15NM longitudinal and lateral separation between surveillance-identified aircraft flying anywhere in the North Atlantic.
Once Aireon is operational in 2018, Enav will use the service and merge the data with legacy, ground-based surveillance systems. This will allow Enav to optimize multiple surveillance layers. The space-based ADS-B data, coming from Italian and neighboring airspace, will be added to the communication network (E-NET). Enav will then have an independent and redundant source of surveillance, to mitigate issues that may arise with existing ground structure surveillance systems such as ground-based ADS-B sensors, rotating radars and telecommunications lines.
Extensive search and rescue efforts following recent high-profile airline disasters have left the general public largely surprised that the exact location of aircraft is often unknown in oceanic and remote airspace. In response, ICAO has recommended that aircraft provide position reports every 15 minutes by November 2018 and several tracking solutions are being considered by airlines, ANSPs and regulators. Unfortunately, there exists a great deal of confusion around what should be considered “surveillance” and what should be considered “tracking”.
