Iridium Communications Inc. has finalized its acquisition of Aireon LLC, securing full ownership of the world’s only space-based ADS-B air traffic surveillance network. The deal, completed 6 July 2026, unites Aireon’s global aircraft tracking capabilities with Iridium’s satcom and positioning, navigation, and timing services on a single network. Aireon will operate as a wholly owned subsidiary under current leadership, with its technology fully integrated into Iridium’s ecosystem. The transaction adds approximately $100 million in annual service revenue and enables real-time surveillance over oceanic and polar regions where traditional radar is absent. Operators now gain a vertically integrated platform delivering aircraft location, pilot communications, navigation integrity, and operational data analytics globally.
