BAE Systems has entered full-rate production and commenced initial deliveries of its NavGuide GPS receiver, a portable, field-installable system designed to provide secure military M-Code positioning, navigation, and timing for vehicle, handheld, and sensor-based applications.
The production milestone marks the close of a development arc that began at JNC 2023 in San Diego, where BAE first unveiled NavGuide as the designated successor to the Defense Advanced GPS Receiver. DAGR, which has powered both handheld and vehicle-integrated GPS for global defense forces for over two decades, used SAASM technology alongside dual-frequency encrypted signals to resist jamming and spoofing. More than 650,000 units were fielded internationally before production concluded.
NavGuide transitions that installed base to M-Code — the military GPS signal purpose-built to defeat modern electronic warfare threats. The compact, lightweight receiver features an intuitive full-color user interface with waypoint navigation and a moving-map display for enhanced situational awareness. It also provides 9-line targeting capability, meets key military environmental requirements, and is compatible with existing FRPA and anti-jam electronic units.
The integration story is central to the program’s value proposition. NavGuide is backwards compatible with existing DAGR installations and is designed for rapid integration into existing mounts and accessories without mission interruption — with an average installation time across more than 30 vehicle platforms of under two minutes, requiring no changes to existing cables, mounts, or vehicle software.
NavGuide sits within a broader M-Code receiver portfolio BAE unveiled at JNC 2025 in Cincinnati. The company’s security-certified Common GPS Modules leverage the M-Code signal across a product line that scales from the world’s smallest and lowest-power M-Code GPS for SWaP-challenged applications to highly robust receivers with integrated anti-jam antenna electronics for exceptionally challenging environments. The full portfolio includes the ASR-M, DIGAR-300M, MPE-M, MicroGRAM-M, NavFire-M, NavStrike-M, NavStorm-M, and SABR-M alongside NavGuide.
BAE has delivered selective availability anti-spoofing modules to users in more than 45 countries and is now fielding M-Code GPS receivers in multiple formats for U.S. armed forces and allied nations. NavGuide is available to all U.S. service branches and to partner nations through foreign military sales. Production is based at BAE’s engineering and manufacturing facility in Cedar Rapids, Iowa.
“NavGuide is more than just a replacement for DAGR,” said Luke Bishop, director of Navigation and Sensor Systems at BAE Systems. “Built on the same trusted foundation for easy installation and transition, it delivers a more resilient, user-friendly M-Code GPS solution. Now in production, NavGuide gives warfighters the precise positioning data and situational-awareness tools they need to stay effective in modern, contested, multi-domain operations.”
