MRU H

The MRU H is an essential instrument constructed for precise motion measurements in marine environments. With applications that stretch from offshore cranes to echo sounders, it is also valuable for ship motion monitoring, helideck motion monitoring, hydroacoustic positioning systems, and hull stress monitoring. Its output encompasses significant data such as roll, pitch, and heave alongside linear acceleration in 3-axes, enabling accurate heave position, velocity, and acceleration in adjustable frames with additional outputs like angular rate vectors.

Embodying three accurate accelerometers and MEMS angular rate gyros, the MRU H achieves remarkable reliability with no rotational or mechanical wear-out components. A distinctive feature of its function is the PFreeHeave algorithm, which uses historical measurements to deliver a precise, phase-free heave signal. This is especially beneficial in conditions of long swell or for seabed mapping applications that can utilize slightly time-lagged heave signals.

Accompanied by user-friendly Windows-based configuration software, the MRU H allows for meticulous calibration of monitoring points and alignment with the vessel's center of gravity. It offers multi-point heave measurement outputs and compatibility with various protocols for seamless data sharing across multiple users. This capability underscores its adaptability to diverse operational needs while ensuring widespread accessibility through established data communication standards.
