KONGSBERG’s MRU-M-SU1 is a Motion Reference Unit designed for offshore applications where precise attitude determination and motion compensation are required. The device utilizes advanced solid-state sensor technology, including a three-axis gyroscope, three-axis accelerometer, and three-axis magnetometer, and possibly a built-in GPS receiver, to provide a full range of motion measurements, including attitude, position, and speed parameters, with output data frequencies up to 100Hz.

The MRU-M-SU1 is designed with high reliability and accuracy in mind in dynamic Marine environments, and is suitable for many fields such as maritime, aviation, and transportation. It can measure the attitude, position, speed, etc. of moving objects such as ships, aircraft, and automobiles to ensure accurate navigation and positioning in various maritime activities.

Typical applications of the motion reference unit include navigation logging, dynamic positioning systems, and antenna compensated roll and pitch measurements. The MRU-M-SU1 must be mounted in a fixed orientation relative to the vessel and is suitable for applications with limited roll and pitch range. If unlimited mounting directions and/or an unlimited mounting range are required, KONGSBERG recommends using MRU models that have sensors on all three axes.
