The Aeroflex APM-424(V)5 Identification Friend or Foe (IFF) portable test set has received an approved for test notification from the US Department of Defense (DoD) AIMS International Program Office.
This approval authorizes IFF end users and customers to use the APM-424(V)5 in platform integration and validation systems. AIMS refers to the DoD International Air Traffic Control Radar System, Identification Friend or Foe, Mark XII/MarkXIIA Systems Program Office.
The portable MK12A Mode 5 Level 2 test set has KIV-77 support replaces the AN/APM-424(V)3, TS-4530, and TS-4530-1. For customers with existing test sets, mode 5 upgrade kits are available. Upgraded units can be used with current technical orders/technical manuals.
IFF Mode 5 is a cryptographic identification system that enables military and international interrogation systems to distinguish friendly aircraft, vehicles, or forces, and to determine their bearing and range from the interrogator. As mode 5 is deployed, newly installed transponders and interrogators require initial commissioning tests followed by routine pre-mission tests.
The Aeroflex APM-424(V)5 is a lightweight flight line test set for non-commercial, pre-mission testing of IFF transponders and interrogators. It tests the latest development in secure IFF mode 5. Levels 1 and 2 are crypto-secure with enhanced encryption, spread spectrum, modulation, and time of day authentication.
Its transponder test mode verifies mode 5 code load and mission/platform parameters. The interrogator test mode verifies mode 5 code load and correct decoding of mission/platform parameters. The test set also supports mode S for military air transport aircraft EHS/ELS and ADS-B.
With removable housings, the APM-424(V)5 will support both the KIV-77 and KIV-78 crypto appliqués.
