Antenna Alignment

To measure the slip angle, try to get the alignment of the antennas as close as possible to the centreline of the vehicle. You can remove any residual errors in this alignment by using the Auto Align feature.

Select Auto-align to start the alignment process. 

Note: You will need to drive in a straight line at a constant speed of more than 25 km/h for a short period of time for the alignment to complete.

Select Clear to remove an already set antenna alignment.

Antenna Level

A procedure to account for vertical deviation between antennas to mitigate any knock-on effect on pitch/roll.

Select Auto-level to start the alignment process.

Select Clear to remove an already set antenna level.
