The MRU-PD is a three-in-one motion reference, DGPS/RTK positioning and HDT (true heading) solution 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 dual-antenna 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, and is compatible with single-and multi-beam echosounders as well as Doppler velocity logs. It is available in an IP67-rated enclosure or a specialized subsea enclosure that enables operation at depths of down to 200 metres.
