Offset survey vessels

A dimensional control or offset survey is regularly performed on vessels to position various sensors on board opposite to each other.

Based on this offset report, the vessel’s parameters can be filled in so that the dredger can dredge flawlessly, the sounding boat can measure and the research vessel can perform its measurements and analysis.

The GNSS/GPS receivers, antennas, IMU (motion sensor), MBES (multibeam echo sounder), SBES (singlebeam echo sounder), the gyrocompass and other sensors are positioned in the ship’s coordinate system.
