Description

Automatic Dependent Surveillance-Broadcast (ADS-B) is a next generation air traffic control (ATC) system, permitting air to air communication or air traffic coordination using a dedicated datalink to determine the aircraft’s exact position in space. ADS-B is a technological solution that is being utilized in an effort to improve the efficiency and capacity of the National Airspace System (NAS). Unlike the conventional radar, ADS-B works at low altitudes as well as on the ground, and thus, can be used to monitor traffic on airport taxiways and runways. Another significant benefit is that it provides radar-like coverage in remote airports or in mountainous terrain where limited or no radar coverage is currently available.
