The Kongsberg RMP420 is a high-performance Reference Motion Unit (RMU) engineered for demanding marine and offshore applications. It provides highly accurate, real-time measurements of roll, pitch, and heave, making it an essential component for systems requiring precise motion compensation. The RMP420 is widely utilized in dynamic positioning (DP) systems, hydrographic surveying, vessel motion monitoring, and stabilization of offshore cranes and helidecks. Its robust design ensures exceptional reliability and performance even in the harshest maritime environments, delivering the critical data needed for safe and efficient operations.
