How does a motion Reference Unit work?

Motion reference units are employed in large vessels operating at sea. MRUs capture roll, pitch, yaw and heave measurements with high accuracy to monitor vessel performance. These measurements apply to observing the wave height or determining dynamic positioning.

What is MRU in ship?

SMC Motion Reference Unit, MRU, is a high-performance motion sensor that measures Roll, Pitch, Heave, Sway, Surge, Accelerations, Angular rates and Velocity for any rig, ship or vessel on which it is mounted.

What is MRU in DP?

As a standard sensor requirement in a Dynamic Positioning system, motion sensors (MRU’s) are used to provide data to aid the vessels response to such forces as waves, currents and weather factors.

What is vertical reference unit?

A vertical reference unit (VRU) measures roll, pitch, and yaw and is used for roll damping, compensation, transformation between coordinate systems on a platform and numerous other applications. LORD VRUs provide a variety of options in tactical, high performance and industrial grade environments.

Why do you need a motion reference unit?

Motion Reference Unit – MRU Operating vessels at sea is, by its very nature, a highly challenging activity. In order to undertake tasks such as wave height monitoring, using cranes during rough weather, or determining where vessels are using dynamic positioning, roll, pitch, yaw and heave motion needs to be measured.

What can a multi axis motion reference unit do?

Some multi-axis MRU – Motion Reference Unit unit are capable of measuring roll, pitch, yaw and heave. Inertial navigation systems are oftenly used in aircraft, spacecraft, watercraft, drones, UAV and guided missiles among others.

What does motion reference unit SMC stand for?

Motion Reference Unit SMC Motion Reference Unit, MRU, is a high-performance motion sensor that measures Roll, Pitch, Heave, Sway, Surge, Accelerations, Angular rates and Velocity for any rig, ship or vessel on which it is mounted.

Why do you need a Kongsberg motion reference unit?

In order to undertake tasks such as wave height monitoring, using cranes during rough weather, or determining where vessels are using dynamic positioning, roll, pitch, yaw and heave motion needs to be measured. This is where Motion Reference Units (MRUs) come in and KONGSBERG has been a leader in this field for over 25 years.
