M-CODE is the military GPS signal required by the U.S. DOD for military operations, and is designed to enhance position, navigation and timing (PNT) capabilities and improve resistance to existing and emerging threats to GPS, such as jamming and spoofing. The MUNS-M solution was developed in partnership with Blue Print Subsea, a UK-based company that manufactures a range of handheld underwater navigation products to assist search-and-rescue and locate objects on the seabed.

Military divers face dangerous and complex underwater navigation objectives that require precise positioning and secure anti-jamming capabilities for mission success.

It was designed by divers for divers and is easy to use, neutrally buoyant and self-contained. The system brings divers closer to PNT Assurance through the combination of a modernized GPS receiver and proven diver-based dead reckoning systems.
