Micro IFF Mode 5 Transponder for Tactical UAVs

The RT-2087/ZPX is a complete, low-SWaP Combat ID and Air Traffic Control surveillance system designed to satisfy Identification Friend or Foe (IFF) Transponder and Automatic Dependent Surveillance – Broadcast (ADS-B) requirements for Unmanned Aircraft Systems (UAS) operating both in the battlefield and in controlled airspace.

When combined with a micro-crypto (e.g. KIV-79), small and tactical UAS benefit from interoperability using Mode 5—the latest IFF encryption standard adopted by NATO and its allies. Crypto emulators are available for non-classified development, testing, and NSM operation. ADS-B In is a supported native function providing Detect and Avoid (DAA) functionality. Ethernet control is an available option.
