FlightAware operates a worldwide network of over 18,000 terrestrial ADS-B receivers. This network is comprised of FlightAware users who host ground stations that feed us flight tracking data. The receivers capture real-time positions, multiple times per minute for aircraft flying over land as well as surface movement at hundreds of airports around the world. They can also track aircraft not yet equipped with ADS-B out through a process called multilateration (MLAT).
Hosting an ADS-B ground station improves public flight tracking on FlightAware’s free website and mobile app. Learn more about FlightAware’s terrestrial ADS-B network and how you can join the effort.
