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. The satellite and
transponder properties for the calibration can be selected from a list of service profiles or
supplied manually. The azimuth relative position is the momentary azimuth value of the
ADU, a dynamic value. The Azimuth calibration value is the calculated ADU azimuth value
after an azimuth calibration, a fixed value.
Automatic azimuth calibration with an active VSAT profile
You can enable automatic azimuth calibration, even if there is no line of sight to an azimuth
calibration satellite from the place of installation. To use this feature you must have made a
valid VSAT profile and have activated it. When the vessel leaves the harbor and gets line of
sight to the satellite, the system automatically finds and tracks the satellite and makes the
azimuth calibration. After a successful azimuth calibration the BDU will automatically
disable the setting

If the target satellite is in inclined orbit, the elevation range is extended
accordingly.
