How is Location of a Flight or Aircraft Tracked- (ADS-B Technology)



ADS-B  (Automatic Dependent Surveillance Broadcast) system is widely used globally for real-time tracking of flights. Currently around 60% of passenger aircrafts are equipped with ADS-B transponder. When in flight the aircraft gets its GPS location from the satellite in space. Then ADS-B transponder in the aircraft now transmits the GPS location details (and other information including speed, vertical speed, Skuawk signal etc.) to nearby aircrafts and receivers on land. ADS-B signal is received by the receiver and information is analyzed and sent to base stations (including live tracking systems, ATC).
