ADS-B

Automatic Dependent Surveillance–Broadcast (ADS-B) enables aircraft to broadcast their precise position, speed, and other vital information, enhancing situational awareness for pilots and air traffic controllers. Unlike traditional radar systems, ADS-B operates in real-time, providing more accurate and timely data. ADS-B technology is fundamental to the way Flightradar24 tracks flights.
