Flightradar24
Flightradar24 is a Swedish internet-based service that provides real-time aircraft flight-tracking information on an interactive map. The service displays information including flight numbers, aircraft types, origins and destinations, positions, altitudes, headings and speeds. It also provides time-lapse replays of previous flight tracks and historical flight information.[1]
The service is available through a website and mobile applications. It combines aircraft-position information from multiple sources, including Automatic Dependent Surveillance–Broadcast|automatic dependent surveillance–broadcast (ADS-B), multilateration (MLAT), satellite-based ADS-B and aviation data supplied by other sources.[1][2]
Much of Flightradar24's terrestrial ADS-B coverage is provided by a network of ground-based receivers operated by aviation enthusiasts and other volunteers. The receivers collect broadcasts from aircraft equipped with compatible transponders and transmit the data to Flightradar24. In 2022, the company said that its network included more than 30,000 receivers worldwide.[1]
The company supplements its terrestrial receiver network with satellite-based data and data from the Federal Aviation Administration in the United States. Satellite-based ADS-B enables aircraft equipped with compatible transponders to be tracked in areas where terrestrial receiver coverage is unavailable, including over oceans.[1]
Flightradar24 is one of the largest flight-tracking services in the world.[1] Its data has been used in media reporting and analysis of aircraft movements, including during major aviation and geopolitical events.[1]
