The MRU-E is an enhanced motion reference unit that combines three-axis solid state accelerometers, gyroscopes, magnetometers and barometric sensors and delivers heave, surge, sway, pitch and roll outputs for marine and maritime applications.
With low noise and high accuracy, the sensor provides reliable real-time measurement under challenging surface or subsea conditions, and is ideal for a variety of use cases including bathymetric and hydrographic survey, platform stabilization, and unmanned underwater vehicles.
The unit incorporates a range of algorithms for specific platforms including surface vessels, ROVs and AUVs, buoys, cranes, helidecks and more. Data can be output in standard industry formats including Kongsberg/Seatex, Teledyne and SMC.
