Flightradar24 tracks positions of aircraft in real-time and turns that data into engaging consumer and business applications. The data comes primarily from a proprietary, crowd-sourced network of 40,000+ so-called ADS-B receivers hosted by private individuals and companies all over the world and tracks 200,000+ flights per day. This network of ADS-B receivers is the largest in the world. In addition to ADS-B data, Flightradar24 is able to get positional data for non-ADS-B equipped aircraft through the use of Multilateration (MLAT). The ADS-B and MLAT data is merged with schedule and flight status data from airlines and airports to create a unique flight tracking experience.
