6 Offsets
Before starting the actual measurement, it is important to align all sensors. The configuration contains two
sub-sections for entering the offsets between sensor, GNSS and vessel. All calibration factors can still be
changed in post processing without further consequences.

6.1 Vessel Coordinate system
As shown in the illustration there are three different coordinate systems that apply.
Figure 27 Vessel coordinate system
First there is the ship itself, to which everything should be aligned. The centre axis is the X-Axis, and forward
is positive. The angles are right-hand, so positive angles are clockwise.
