The MRU 5 represents the pinnacle of marine motion sensing technology

– embodying a specially designed fifth-generation device that excels in

delivering high precision motion measurements within marine applications.

It stands out in its ability to offer highly accurate roll, pitch, and heave

measurements for the most demanding users.

High Precision Applications

Primed for excellence, the MRU 5 is the optimal sensor for various motion

compensatory functions used in multi-beam echo sounders, offshore cranes,

hydroacoustic positioning systems, and dynamic motion monitoring on

offshore structures. Its unparalleled roll and pitch accuracy of 0.02° RMS

within a ±5° amplitude is proven and documented, ensuring reliable

performance on any surface vessel or subsea vehicle.
