Aireon

Founded in 2011, it manufactures, deploys, and operates a global aircraft tracking and surveillance system[1] utilizing satellite-based receivers to monitor the existing ADS-B transmissions of aircraft, for global air traffic surveillance.

[2][3][4] Aireon was launched in 2011 as a joint venture between satellite communications company Iridium Communications Inc, Nav Canada, NATS,[5] ENAV,[6] Naviair[7] and the Irish Aviation Authority to work on a surveillance system to track aircraft around the globe, beyond the range of ground-based radar and ADS-B receivers, in real time.

[16][17][18][19][20] National ANSPs including Nav Canada, UK NATS, ENAV, IAA, AAI, Naviair, Isavia, CAAS of Singapore, ATNS of South Africa, DC-ANSP, ASECNA, Seychelles (SCAA), COCESNA Honduras and PNG of Papua New Guinea have signed a Data Services Agreement with Aireon.

[21][22][23][24] ADS-B-equipped aircraft transmit short data packets containing identification, position and other information.

Through its receivers in space, Aireon monitors these transmissions, providing coverage where there is no ground infrastructure, relaying signals from all ADS-B equipped aircraft to controllers.
