Air Traffic Control Beacon Interrogator Model 6 (ATCBI-6)
Description
The Air Traffic Control Beacon Interrogator Model 6 (ATCBI-6) is a ground-based system that interrogates transponders, receives, and processes replies from transponders, determines the range and azimuth to the aircraft, and forwards the information to appropriate air traffic control (ATC) automation systems. Replies provide identification and altitude data of the transponder. The ATCBI-6 Replacement Program will procure about 140 Monopulse Secondary Surveillance Radar (MSSR) with Selective Interrogation (SI) to replace existing operational beacons, which includes four support systems (not shown in the quantities below) for training, testing, logistics, and operational support.
As of December 2008, 137 ATCBI-6 systems had been delivered, 137 delivered to sites and 111 commissioned. Ninety-six (96) legacy ATCBI systems have been removed.
The ATCBI-6 will replace all ATCBI-4 and ATCBI-5 systems at NAS en route facilities. All ATCBI-4 systems will be out of the NAS by the end of 2007. ATCBI-5 systems will be moved to terminal or beacon only site (BOS) facilities.
