Dynamic positioning All position reference system used as input to a DP system, have to be transformed to a common reference point on the vessel. To achieve this, the MRU roll and pitch motion measurements have to be used. Motion damping systems on high-speed crafts Motion damping systems, or ride control systems, require the input of roll/pitch angle and angular rate measurements to the foil control system. The MRU outputs these variables with minimum latency and at a high output rate. Stabilization applications Telecommunication antennas mounted high up in the vessel mast often require...
