- | |||
- | For the autopilot to work correctly the inertial sensors must be calibrated. Typically this is just an offset or bias for each of the sensors. | ||
- | |||
- | Many sensors have accurate accelerometer bias from factory, if not, calibration is needed. | ||
- | |||
- | The gyroscopes continuously automatically update their bias, so calibration is not needed. | ||
- | |||
- | The compass can change widely depending on where it is and what is around it so must be calibrated once mounted to the boat. | ||
