Aireon's space-based ADS-B network, operational since April 2019, gave air traffic controllers real-time surveillance over the North Atlantic for the first time in aviation history.
Aireon's space-based ADS-B network uses 66 low-Earth orbit satellites to deliver 8-second position updates over the open ocean, replacing a system where oceanic controllers worked with data up to 10 minutes old.
How Aireon put ADS-B receivers on 66 Iridium satellites to replace 40-minute oceanic position reports with real-time tracking of every equipped aircraft over every ocean.
Aireon's space-based ADS-B network, hosted on 66 Iridium NEXT satellites, cut North Atlantic position update intervals from 14 minutes to 8 seconds and reduced lateral separation to 15 nautical miles.
How Aireon's space-based ADS-B network, riding 66 Iridium satellites in low Earth orbit, ended decades of blind oceanic air traffic control in November 2019.
