MRU3000 Motion Reference Unit

This Motion Reference Unit gives high performance, is compact and affordable. It use state-of-the-art MEMS technology and advanced sensor fusion algorithms to provide real-time roll, pitch and heave at high frequencies.

Ideal for use in marine applications such as motion compensation of sonars, active heave compensation of offshore cranes, helideck monitoring, DP systems and motion compensation of wave radars, gangways and offshore installations.

It comes in a waterproof, marine housing with ethernet, serial ports and free software upgrades included. A wide range of industry standard and custom protocols are included for easy interfacing to other systems.
