Kongsberg Seatex MRU-5

The third generation MRU 5 is specially designed for high precision motion measurements in marine applications and for users requiring high accuracy roll, pitch and heave measurements. The MRU 5 provides high performance motion data for various marine applications ranging from small underwater vehicles to large ship motion control. Very high reliability is achieved by using solid-state sensors with no moving parts and the proven MRU electrical and mechanical construction.
