Where do flight trackers get their data?

Flightradar24 combines data from several data sources including ADS-B, MLAT and radar data. The ADS-B, MLAT and radar data is aggregated together with schedule and flight status data from airlines and airports to create a unique flight tracking experience on www.flightradar24.com and in Flightradar24 apps.



Flight trackers like FlightAware and Flightradar24 aggregate data from a sophisticated network of global sources to provide real-time aircraft positions. The primary source is ADS-B (Automatic Dependent Surveillance-Broadcast), a technology where aircraft broadcast their GPS-calculated position, altitude, and speed via a 1090 MHz transponder. This signal is picked up by a vast network of over 30,000 ground-based receivers hosted by volunteers and professionals worldwide. In areas where ground coverage is sparse, such as over oceans or remote deserts, trackers use Space-Based ADS-B, which involves satellites (like the Iridium NEXT constellation) receiving the signals from above. Another critical method is MLAT (Multilateration), which calculates the position of older aircraft by measuring the "time difference of arrival" of their signals at multiple ground stations. Furthermore, trackers integrate official radar data from Air Navigation Service Providers (ANSPs) and the FAA, as well as "OOOI" (Out, Off, On, In) data directly from airline dispatch systems. This fusion of terrestrial, satellite, and government data allows for nearly 100% global coverage of commercial and private aviation.

Published Airline Schedules is the first ingredient in building flight status. We ingest a daily schedule file produced by the Cirium team and normalize the data. Data elements include routing, scheduled block times, codeshares, equipment type, flight type (cargo / passenger), and traffic restrictions.

While flight tracking information can provide useful climate information, it can also pose high-risk threats to safety and privacy if users escalate from comments behind computer screens to the physical locations shared in real time.

I was following an aircraft when it suddenly disappeared, why? In most cases, our receiver network is no longer receiving a signal from the aircraft. This tends to be more common when an aircraft is flying over large bodies of water. It can also be a technical problem somewhere.

Flightradar24 is the more customizable of the two, and while FlightAware says it tracks more flights, it lacks options like showing planes on the ground. (There's also a third flight-tracking app and website, Planefinder, which looks and feels similar to Flightradar24 and has the same price for the premium version.)
