AN/UPX-39(V)2 Monopulse Secondary Surveillance Radar (MSSR) IFF Interrogator
The AN/UPX-39(V)2 Monopulse Secondary Surveillance Radar (MSSR) system is being delivered to replace the aging Identification Friend or Foe (IFF) interrogators in the U.S. Air Force SEEK IGLOO/North Warning AN/FPS-117 radars that support the Air Force Atmospheric Early Warning System. These long-range surveillance radar systems are located at 33 sites across the northern perimeters of Canada, Alaska, and Iceland, and they are in Hawaii, and Puerto Rico. These systems are dual-use sites that provide ATCRBS, Mode 4 and Mode S Level 2 aircraft data to the Air Force and Federal Aviation Administration (FAA) control centers.
The Air Forces Atmospheric Early Warning System provides military aircraft identification and commercial air traffic surveillance for up to 256 nautical miles. The AN/UPX-39(V)2 replaces thirty-year-old analog equipment with modern, digital Commercial Off-The-Shelf (COTS) equipment. The AN/UPX-39(V)2 Interrogator meets current STANAG 4193 and ICAO Annex 10 standards of air traffic control system requirements. It also adds remote control, Beacon Performance Monitor, and fault isolation capability. The reliability, maintainability and supportability of the AN/UPX-39(V)2 significantly lower maintenance costs for the Air Force.
