Kongsberg MRU-M-SU1 Marine Motion Reference Unit

The Kongsberg MRU-M-SU1 is a precision marine motion sensor engineered for real-time measurement of vessel dynamics. It accurately captures six degrees of freedom: heave, surge, sway, roll, pitch, and yaw. This rugged system is essential for offshore drilling operations, naval navigation systems, oceanographic research vessels, and dynamic positioning applications where motion compensation is critical.
