The Irish Aviation Authority is a partner and shareholder in Aireon LLC, a revolutionary space-based air traffic surveillance venture, along with Iridium (USA) and the air navigation service providers - NATS (UK), NAV CANADA, ENAV (Italy) and Naviair (Denmark).
Aireon has deployed the first global air traffic surveillance system using a space-based Automatic Dependent Surveillance Broadcast (ADS-B) network that meets the strict, real-time Air Traffic Service (ATS) surveillance requirements for separation services, anywhere in the world. ADS-B is an air traffic surveillance technology that relies on the aircraft broadcasting their identity, a precise Global Positioning System (GPS) position and other information derived from onboard systems. The data is broadcast every half-second from the aircraft and is used by Air Traffic Controllers (ATCs) to identify and separate aircraft in near-real time. ATS surveillance is clearly defined by the International Civil Aviation Organization (ICAO) but, put simply, it’s the ability to reliably, and in near-real-time detect key flight attributes such as position, level and intent. Space-based ADS-B provides full, continuous global air traffic surveillance, whereas before, 70 percent of the world had no access to ATS surveillance information (i.e. the oceans, polar regions, mountainous regions, jungles, deserts). This significantly improves Air Traffic Management (ATM) safety, efficiency, predictability and capacity, while reducing overall infrastructure costs.
The backbone of Aireon’s technology resides on Iridium constellation of satellites. Eight Iridium launches on Space-X Falcon 9 rockets successfully occurred between January 2017 and January 2019. Iridium’s next generation satellite constellation is delivering exciting new innovations and opportunities, while ensuring continued high performance and reliability, far into the future. Iridium is hosting Aireon’s specially designed receivers on each Iridium satellite, covering 100 percent of the globe. Iridium’s low-latency, 66 cross-linked Low Earth Orbit (LEO) satellites make it uniquely suited to meet the technical demands of global air traffic surveillance and tracking.
Space-based ADS-B bypasses the limitations of ground-based systems and provides an operational, global, space-based air traffic surveillance solution to all aviation stakeholders.
What is Aireon Alert
Aireon Aircraft Locating and Emergency Response Tracking (ALERT) is the aviation industry’s first and only free global emergency aircraft location service. Air Navigation Service Providers (ANSPs), commercial aircraft operators/airlines, 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. As a free service, Aireon ALERT fills 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.
Aireon ALERT utilizes Aireon’s space-based ADS-B data and is 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. All users simply have to register for the free emergency service.
