The MRU-P is a high-performance motion reference unit that provides robust heave, surge, sway, pitch, roll, heading and position data for naval and marine applications such as survey platforms and autonomous and unmanned vessels. Featuring advanced MEMS accelerometers and gyroscopes and an RTK-capable multi-constellation GNSS receiver, the sensor delivers accurate real-time measurement even under the most demanding of conditions.

The unit can be configured to output proprietary message formats or other industry formats such as Kongsberg, Seatex and Teledyne TSS, enabling easy integration and replacement of older legacy systems. It is available in an IP67-rated enclosure or a specialized subsea enclosure that enables operation at depths of down to 200 metres.
