A Motion Reference Unit, commonly known as an MRU, is a high-precision instrument crucial for marine and subsea operations. Its primary function is to accurately measure the motion of the vessel or platform upon which it is mounted. It provides real-time data on angular rates (roll, pitch, yaw) and linear accelerations (heave, surge, sway). Essentially, it quantifies how the platform is moving, tilting, and turning in all six degrees of freedom (6DOF). At the heart of an MRU are sophisticated inertial sensors, typically including gyroscopes and accelerometers, which detect these subtle or significant movements even in challenging sea conditions.
