Description

KONGSBERG MRU-E-CS1-3M – Motion Reference Unit for Marine Motion Sensing

Product Overview

As a fifth-generation sensor, it integrates three MEMS angular rate gyros and three high-accuracy accelerometers to deliver real-time roll, pitch, heave, and 3-axis linear acceleration data. Engineered for extended temperature operation, it addresses critical needs for motion compensation, dynamic positioning, and surveying on vessels, offshore platforms, and autonomous marine systems.
