Air Traffic Control Beacon Interrogator

Air Traffic Control Beacon Interrogator - Model 6 (ATCBI-6)

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 129 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.

Through Fiscal Year (FY) 2005 135 systems had been ordered, 77 systems had been delivered to sites, and 51 systems commissioned. As of 17 November 2005 54 ATCBI-6 systems had been commissioned.

In FY 2006 up to 15 March 2006 five systems had completed Initial Operational Capability (IOC), and nine additional systems had been delivered.
