M5000
The M5000 is a powerful FOG and quartz-based inertial navigation system that provides robust navigation, position and attitude control capabilities for subsea platforms such as crewed and uncrewed underwater vehicles. Featuring a built-in multi-frequency GNSS receiver, it can be integrated with an external Doppler Velocity Log and outputs a range of critical precision real-time data such as attitude, heave, heading, position, and velocity.
Available in three different performance variants, the rugged INS is housed in a titanium pressure-resistant and watertight housing that is rated to 3000 or 6000 meters. Data can be output via serial RS-232/RS-422, Ethernet or PPS.
