Compass linearization — Evolution autopilots
The EV sensor’s internal compass needs to compensate for local and the
Earth’s magnetic fields. This is achieved using an automatic process known
as linearization.
Initial linearization
When the EV sensor is first installed and powered-up (or after a factory
reset or compass restart) linearization is required. When linearization is in
progress bar is displayed in the Autopilot settings page:
