3.1 About this Chapter
Before the ST30 Compass system can be used as a navigational aid, the
fluxgate compass MUST be linearised to compensate for deviation and the
displayed heading MUST be aligned to a known transit bearing.
Other calibration features allow you to adjust the speed at which the
heading and heading error displays are updated.
3.2 User Calibration
User calibration contains features to perform compass linearisation and
heading alignment.
Manual Compass Linearisation
