RT-2087/ZPX-1

Micro IFF Mode 5 Combined Transponder – Receiver for Tactical UAVs

The RT-2087/ZPX-1 is a complete, low-SWaP Combat ID system designed to satisfy Identification Friend or Foe (IFF) Transponder and Automatic Dependent Surveillance – Broadcast (ADS-B) requirements for Uncrewed Aircraft Systems (UAS) operating both in battlefield and civilian controlled airspace.

When combined with a micro-crypto e.g. KIV-79, UAS as small as Group 1 have available the latest IFF encryption standard used by NATO and its allies. Continuing the spirit of low SWaP, the ZPX-1 offers AIMS-certified RT-2087/ZPX users an upgrade path that includes Mode S Enhanced Surveillance (EHS), ADS-B IN, and Mode 5 squitter Level 2/2-B IN receive capability for Detect and Avoid.
