Automatic Dependent Surveillance-Broadcast

ADS-B Technologies


ADS-B technology will be replacing conventional radar-based surveillance as the primary method for identifying and tracking aircraft in U.S. airspace.

Using the ADS-B datalink, each airplane will automatically transmit its precise position, its velocity (both vertically and horizontally), as well as its altitude and other information to controllers and other nearby aircraft.

Each plane will need a WAAS-capable GPS receiver to provide the high-integrity location and flight path data for ADS-B networking.
