The DMS range of motion sensors is designed specifically for the motion measurement needs of the marine industry. Whether it is achieving IHO standard survey from any size of vessel, or providing safety critical monitoring of offshore platforms, large vessels, helicopter landing decks, cranes and positioning systems, the DMS provides accurate motion measurement in all sea conditions.
Incorporating an enhanced external velocity and heading aiding algorithm for improved accuracy during dynamic manoeuvres, the solid state angular rate sensors offer reliability in the highest performing vertical reference unit ever produced by TSS.
The MRU 5 is the ideal sensor for motion compensation of multi-beam echo sounders, offshore cranes, hydroacoustic positioning systems and dynamic motion monitoring of roll, pitch and linear accelerations on offshore structures. The MRU 5 provides documented roll and pitch accuracy of 0.02° RMS at a ±5° amplitude. The unit maintains its specified accuracy aboard any surface vessel or subsea vehicle.
The MRU 5 incorporates three highly accurate accelerometers and three high-end Kongsberg Seatex developed MicroElectro-Mechanical-Structures (MEMS) gyros of type MRG (MRU Rate Gyro). The MRG gyro combines low noise, excellent bias stability and gain accuracy. Very high reliability is achieved by using solid state sensors with no rotational or mechanical wear-out parts.
