The US Army has greenlit the full-rate production of a vehicle-mounted anti-jamming GPS system from Collins Aerospace. The Mounted Assured, Positioning, Navigation, and Timing System (MAPS) GEN II is designed to ensure operational effectiveness in highly contested environments where military GPS signals are denied or degraded.
Developed by Collins Aerospace, MAPS GEN II provides GPS anti-spoofing and anti-jamming capability through sensor fusion algorithms and non-radio frequency sensors. The system distributes positioning, navigation, and timing data to multiple clients on a single platform, eliminating redundant GPS receivers and antennas.
The Army’s cross-functional team established in 2017 has made significant progress in developing this capability. The system consists of NavHub-100, which generates and distributes assured PNT information to all systems onboard the platform through a singular device. The DIGAR-100 anti-jam antenna provides superior immunity in severe GPS-challenged environments.
Rigorous testing was conducted before the full-rate production approval, with an Initial Operational Test & Evaluation (IOT&E) at Yakima Training Center in February 2024. The Army plans to procure 619 MAPS GEN II systems for a total of $130 million in fiscal year 2025, including spares, follow-on tests, and evaluations.
This system will enhance the Army’s capabilities against electronic attacks and provide seamless operation in environments where GPS signals are degraded or denied.
