Some of the applications where our Motion Reference Units are used

Helideck Monitoring

Accurate measurement of roll, pitch, and heave motions is crucial for assessing the safety of helidecks during helicopter landing and take-off operations.

Wave Radar

Accurate heave measurements play a vital role in compensating for Wave Radar measurements when installed on ships or other floating vessels.

Active Heave Compensation

Accurate measurement of vertical motion at the crane tip or winch is crucial for the operation of Active Heave Compensated (AHC) cranes and winches.

Motion Compensated Gangways

Accurate measurements of all 6 degrees of freedom are essential for the automatic motion control of gangways.

Sonar Motion Compensation

Accurate measurements of roll, pitch, and heave are crucial for achieving optimal results when compensating sonar systems for vessel motion, without relying on GNSS or RTK.

Dynamic Positioning

Dynamic positioning (DP) of vessels necessitates roll and pitch compensation of the GNSS antenna to ensure accurate positioning of the ship's control point.
