AN/UPX-39(V)1 Monopulse Secondary Surveillance Radar (MSSR) IFF Interrogator
The AN/UPX-39(V)1 Monopulse Secondary Surveillance Radar (MSSR) is a completely new interrogator designed for the most demanding Air Traffic Control System requirements and to replace aging IFF interrogators that can no longer be maintained.
The AN/UPX-39(V)1 replaces outdated analog equipment with modern, digital Commercial Off- The-Shelf (COTS) equipment. The AN/UPX-39(V)1 meets current military, Federal Aviation Administration (FAA) and international standards for Identification and Air Traffic Control system requirements as well as adding Remote Control, Monitor and Fault Isolation capability. The reliability, maintainability and supportability of the AN/UPX-39(V)1 significantly lowers maintenance costs.
The AN/UPX-39(V)1, also known as the beacon subsystem, is a long-range interrogator with 2,000 watts of output power, ISLS operation, three receiver channels, RSLS, GTC/STC, Target Extractor, and Target Tracker.
The AN/UPX-39 outputs Digital Target Reports in ASTERIX, CD2 or a host of other common formats over Ethernet, RS-232 or other standard bus to the primary radar or Air Traffic Control (ATC) station. The AN/UPX-39(V)1 MSSR interrogator provides ATCRBS, Mode 4 and Mode S Level 2 aircraft data to the ATC center or weapon systems operator.
