Navy taps to design an innovative, NSA-authorized Micro IFF Transponder for Unmanned Aerial Vehicles.

Current Identification, Friend or Foe (IFF) transponder systems were designed for manned aircraft. However, their size and power consumption requirements make transponders difficult to incorporate into Unmanned Aerial Vehicle (UAV) designs. Even IFF Crypto appliqués are too large and heavy for small UAVs. IAI proposes the design of a miniature IFF Transponder that is capable of receiving the required interrogations (Mode 1, 2, 3/A, C, S, 4, 5), providing the related replies, and managing the ADS-B (ADS-B, TIS-B and FIS-B) and ADS-B Out messages complying with the RTCA DO-160B and DOD AIMS 03-1000B standards, within a 3.5 cubic inches of volume. In order to meet these stringent requirements, IAI will leverage the state-of-the-art System-on-Chip (SoC) approaches to implement single-chip crypto system architecture. Highly integrated transceiver circuits, pulse-biased amplification schemes, and SoC based power management will be used to reduce the IFF Transponder form-factor, improve efficiency, and greatly reduce quiescent device heat dissipation. IAI’s solution is ideal for battery-powered UAV applications and complies with the Federal Aviation Administration (FAA) initiatives to integrate UAVs into the National Air Space by enabling large-scale commercial UAV use.
