Norwegian Subsea Motion Reference Unit

Norwegian Subsea has announced that it has released an upgraded version of its NORSUB MRU 6000 Motion Reference Unit, for OEM and Marine unmanned vehicle applications such as USVs (Unmanned Surface Vehicles) and ROVs (Remotely Operated Vehicles). MRU 6000 outputs roll, pitch, heave, surge and sway measurements at high frequencies. The unit builds on state-of-the-art MEMS technology and advanced sensor fusion algorithms.

MRU 6000 is well suited for a wide range of applications including active heave compensation, hydrography, hull monitoring and DP (dynamic positioning) systems. The OEM version is compact, light-weight and easily integrates into 3rd party systems such as sonars and metocean instruments. MRU 6000 comes with ethernet and serial ports, and many industry standard and custom protocols are included for easy interfacing. Users can build their own custom defined protocol from a list of all available output variables. There is no need for re-calibrations once the unit has been installed, different to many other MRUs where re-calibrations are typically required every two or three years.
