Motion Reference Unit - MRU Operating vessels at sea is, by its very nature, a highly challenging activity. In order to undertake tasks such as wave height monitoring, using cranes during rough weather, or determining where vessels are using dynamic positioning, roll, pitch, yaw and heave motion needs to be measured. Motion reference units (MRU) determine the orientation of an object relative to an inertial frame of reference or another body. To control this data output, referred to as attitude, MRUs integrate sensors for orientation measurements, as well as actuators for applying torque to position an object to the desired attitude.

The Motion Reference Unit (MRU) product line was first released in 2004 when Inertial Labs MEMS-based sensor solutions began to compete in performance with traditional FOG units. Easy integration of the MRU product line for the end user means competitive performance at no extra cost. An IMU (sometimes referred to as an inertial reference unit [IRU] or motion reference unit [MRU]) is typically an electromechanical or solid-state device that contains an array of sensors that are able to measure motion. Precise and Cost-Effective Motion Reference Unit (MRU) for Boat Motion Monitoring In this example, the GNSS-aided MRUs are installed on both the boat approaching the platform and the platform itself. They sense in real-time the motion to stabilize the boat and the floating platform. Ekinox-A is an advanced Attitude & Heading Reference System (AHRS) or MRU (Motion Reference Unit). It combines high end gyroscopes and accelerometers and runs an enhanced Extended Kalman Filter (EKF) to provide Roll, Pitch, Heave, and Heading when connected to an external GNSS receiver. 0.02° Roll and Pitch (RTK) 0.05° GNSS Heading

Motion Reference Units or MRUs use gyroscopes and accelerometers to measure the roll and pitch (attitude) of an object with reference to the absolute vertical. In addition to the attitude, MRUs also measure vertical displacement of the object relative to some initial starting point (typically the sea surface).
