Overview
The MRU-B1S Basic Subsea MEMS MRU from Inertial Labs was developed to meet requirements for echosounder scanning systems and subsea heave compensation applications. This MRU is an enhanced, high-performance strapdown motion sensor, that determines heave, sway, surge, and heading (optional) for any device on which it is mounted.
The MRU-B1S utilizes 3-axis solid-state precision accelerometers, magnetometers, gyroscopes and barometric sensors to provide accurate heave, sway and surge of the device under measure.
Integration of these very low noise gyroscopes allow for output which provides high frequency, real-time rotation measurement for vessels, ships, helidecks, ROV, marine antennas or cranes over all three rotational axis.
The new generation of Inertial Labs MRUs are an ideal solution for demanding applications. Their electronic nature solves the problems associated with expensive mechanical gyro solutions, as well as fiber optic gyro (FOG) technology. These high-end MRUs feature MEMS gyros that lead the sector in both accuracy and reliability.
