On September 2, 2021, the American defense company Collins Aerospace announced the release of the world's first portable military diving navigation system ArtemisPRO-M, suitable for processing GPS signals in the military code M (MUNS-M). According to the manufacturer, the enhanced system allows combat swimmers or mine divers to accurately determine their position, while remaining at a great depth, protected from interference.
The M-code is a GPS signal provided by the US Department of Defense in the interests of conducting military operations. It is designed to improve location, navigation and time detection (PNT), as well as increase resistance to existing and emerging threats to GPS, such as interference and spoofing. The GPS signal used by civilians is much weaker, and therefore more vulnerable. The MUNS-M solution was developed in partnership with the British company Blue Print Subsea, which produces a number of portable underwater navigation devices used during search and rescue operations and the detection of objects on the ocean floor.
ArtemisPRO-M navigation system
According to the manufacturer, the ArtemisPRO-M navigation system has the following functionality:
- Built-in upgraded GPS receiver and separate upgraded GPS receiver (floating receiver) with Y-code, M-code and C/A-code (YMCA) and L1 / L2 antenna technology;
- multipath sonar for obtaining real-time images in poor visibility conditions;
- AHRS (Attitude Heading Reference System) sensors for obtaining magnetic course information and attitude control;
- Doppler Velocity Log (DVL) for obtaining navigation data based on information about the course, speed and altitude of navigation over the seabed;
- built-in acoustic transponder and data modem for text communication and location determination from diver to diver and from surface to diver, video / camera and diving lamp;
- pressure sensor for determining the exact depth of immersion;
- customizable offline data protocol for mission assessment and analysis
