MRU 5

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.

Integrating three top-tier accelerometers with three premier Kongsberg Seatex developed MEMS gyros of MRG type, the MRU 5 exhibits low noise characteristics alongside exceptional bias stability and gain accuracy. This high reliability is attributed to the use of solid-state sensors, which circumvents any mechanical wear. Adding to its feature set, this unit comes with specialized Windows-based configuration and data presentation software, which allows for the precise definition of vector arms to the center of gravity and two individually configurable monitoring points.

The MRU 5 is proficient in the output of critical motion-related variables, such as roll, pitch, and yaw angles as well as angular rate vectors across various adjustable frames. Furthermore, with the employment of the cutting-edge PFreeHeave algorithm, it overcomes the perils of long swell conditions and is ideal for applications that can utilize a delayed heave signal, commonly observed in seabed mapping operations. External speed and heading inputs are also accepted to augment the accuracy of heave, roll, and pitch under dynamic conditions.
