The Air Traffic System: concepts and technologies

摘要

The US Faa envisages a metamorphosis of the country's ground-based air traffic control (ATC) network to the Next Generation Air Transportation System (NextGen) that provides air traffic management through the satellite-based Automatic Dependent Surveillance - Broadcast (ADS-B) system. Use of ADS-B, through an appropriate transponder, enables an aircraft to obtain its exact location from GPS satellites and continuously broadcast it with other flight information to other aircraft and ground stations, under the designation ADS-B Out.
