Air Traffic Control Beacon Interrogator

The FAA and DOD maintain several Beacon Interrogator Systems (ATCBI-4, ATCBI-5, ATCRBS, and Mode-S) within the National Airspace System (NAS). These systems assist with air traffic control by supplying aircraft identification, altitude, airspeed and direction. These systems are normally used as secondary surveillance radar fielded with an ASR (terminal) or an ARSR (enroute) system. They can also be used as a stand-alone system to provide additional radar coverage within the NAS.

ATCBI: The Air Traffic Control Beacon Interrogator (ATCBI) transmitter interrogates transponders that are located on aircraft, while its receiver detects and processes the responses from the aircraft transponders. The ATCBI system supplies positive identification and altitude information, allowing controllers to track each plane more precisely and efficiently.
