Elevation Alignment

It is fairly easy to observe errors in the elevation calibration.

If test data shows that the actual elevation angle that a satellite is found is consistently above or below the calculated target, then it can be concluded that an elevation offset should be applied. Enter the appropriate value in the OFF field of the elevation calibration screen (3.3.1.3.2).

If the difference between actual and calculated elevation angle is not consistently of the same magnitude, then the calculated elevation inclinometer scale factor should be questioned. Step 4 of the elevation calibration procedure should possibly be rerun.

Also consider that a combination of elevation offset and inaccurate scale factor may be applicable. Rerun tests across the arc of satellites to confirm that applied corrections yield good results.

Azimuth Alignment

It is not as easy to observe errors in azimuth calibration. This is mainly due to the fact that the error from the compass reading will not be consistent from location to location and even from different vehicle headings at the same location.

If, after multiple tests, a consistent error in actual vs. calculated azimuth target is observed, then a modification of the offset in the azimuth calibration screen may be applied.
