How to adjust bearing error
To adjust bearing error which is caused by gyro, you have three different alternatives:
1. Manual
•
Adjust value of manual gyro correction.
2. Table based gyro speed/latitude correction (Note! The build in correction inside the ECDIS
doesn't correct dynamic error: settling time after course change etc.)
•
Switch selection Gyro speed/latitude correction to ON position.
3. Use Reference targets to make gyro correction (automatic).
See example below, how to use manual gyro correction.
No manual gyro correction.
Note!
ARPA targets and radar echo overlay match perfectly.
Chart features and radar echo overlay have some miss match.
