calibration afterwards.
6.2.2.2 Azimuth calibration
Azimuth calibration is done toward a satellite of a known position.
After finding the satellite, the system can calculate the azimuth
offset of the ADU installation. The satellite and transponder
properties for the calibration can be selected from a list of reference
satellites or supplied manually.The calibration has 2 steps: Azimuth
calibration and cable calibration.
There are 2 ways to make an azimuth calibration:
• Using a service profile.
• Using user defined input on the calibration page.
To make an azimuth calibration with a service profile, do as follows
