The US Army has approved the production of a new vehicle-mounted positioning, navigation and timing (PNT) system to help soldiers operate in GPS-denied environments. The Mounted Assured PNT System, or MAPS, is designed to provide anti-jamming capability through sensor fusion algorithms, allowing mounted troops to navigate and communicate even when military GPS is unavailable.
The system consists of an internally mounted navigation hub that fuses data from sensors and receivers, as well as an anti-jam antenna system on the outside of the vehicle. The Army plans to procure 619 MAPS GEN II systems for $130 million in fiscal 2025, which will include spares, test and evaluation, logistics support, and engineering changes.
The approval marks a significant milestone in the Army’s modernization efforts, with a total procurement cost of around $500 million for the mounted PNT program. The system is expected to provide GPS anti-spoofing and anti-jamming capability, eliminating redundant receivers and antennas.
