Chapter 5: Compass Calibration
Important note
The procedures in this chapter only apply if:
• you have not been able to install the fluxgate compass on a forward facing
bulkhead
or
• the SportPilot takes up an incorrect waypoint heading when operating in Nav-
igator (Track) mode
Introduction
The SportPilot requires a heading reference to compensate for Northerly turning
errors. In Navigator (Track) mode it also needs a heading reference to turn the
boat towards the next target waypoint.
The SportPilot can usually obtain accurate heading information by attaching the
fluxgate compass to a forward facing bulkhead (as described in
Chapter
4:Installing the SportPilot
).
However, if you are unable to mount the compass in this way or if the SportPilot
steers onto the wrong heading, you must carry out compass linearization and
heading alignment procedures in this chapter. These procedures ensure that the
reading from the fluxgate compass corresponds to the heading displayed by your
boat’s compass.
