FAQ

What is the Operation of Motion Reference Units?

MRUs utilize motion sensors with a single-axis or multi-axis configuration. They incorporate gyroscopes capable of detecting motion in space without the need to track external objects. Gyroscopes come in a variety of types. Select models feature a spinning mass or ring lasers that reflect light to detect rotation. Other types include the hemispherical resonator gyro (HRG), also known as the wine-glass gyroscope. An HRG calculates the orientation of oscillation, created by a resonating shell in the inertial space, in relation to the position of a moving object.

Vibrating gyroscopes operate based on Coriolis forces that generate vibration patterns around the rotation axis and apply the acceleration effect to sense rotation.

A miniature gyroscope manufactured using MEMS (micro electronic mechanical system) technology provides an inertial measurement unit (IMU). Optional units integrate multiple gyros and accelerometers.

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.
