BAE Systems’ Reduced Size Transponder, which fits into the palm of a hand, is used to identify aircraft and ships as friendly forces,  reducing the risk of fratricide.

At half the size and weight of currently fielded transponders, our system, known as the AN/DPX-7 Reduced Size Transponder (RST), is used to identify and track aircraft and ships, thereby reducing the risk of friendly fire. Now, we’re proud to announce the system has received an important Department of Defense (DOD) accreditation, commonly referred to as the AIMS certification, making it available to improve navigation and identification capabilities on a range of existing and emerging military platforms including unmanned aircraft systems (UAS), ships, helicopters, and fixed-wing aircraft..

“To achieve AIMS certification for our smaller, cost-effective IFF product means that our system meets the stringent performance standards established by the DOD,” said Sal Costa, product line director for Identification & Processing Solutions at BAE Systems. “Our AN/DPX-7 system will make air travel safer because it enhances the capabilities of air traffic control, communicating with other planes, satellites, and ground stations.”

No other currently fielded Mode 5 transponder offers a package this size that provides both air traffic control and situational awareness for pilots. Used for military platforms which require Mode 5 functionality, the system has been selected for the MQ-4C Triton, a UAS that provides surveillance capabilities for the U.S. Navy. The RST can also be configured to replace legacy fielded military transponders.
