6.3.6.3 Further information about azimuth adjustment
The purpose of the Azimuth Adjustment is to significantly reduce the
risk of tracking the wrong TV satellite by compensating for errors in
the heading input. This is necessary because there is no universal
way to identify the TV satellites except from their position.
If enabled (default), Azimuth Adjustment runs before attempting
acquisition on the TV satellite selected in the satellite profile. The
procedure attempts to acquire and briefly track the signal from one
of the reference satellites in the systems database. If Azimuth
Adjustment fails (by not finding any of the reference satellites), the
system will proceed and attempt to acquire and track the TV Satellite
selected by the user. Thus, the system always ends up trying to
acquire the signal from the TV Satellite selected by the user. The
Azimuth Adjustment takes a few minutes whether it succeeds or
fails.
If the system is tracking the TV Satellite and loses the signal (e.g.
due to a blocking zone) Azimuth Adjustment will run again before
the system attempts to re-acquire the signal from the TV Satellite.
The system will ensure that brief blocking of the signal will not
deem the signal as lost.
The database with the reference satellites contains information
about which reference satellites to use at given positions. Currently,
there is a maximum of three satellites for any given position. This
means that the Azimuth Adjustment procedure attempts acquisition
on a maximum of three satellites before it fails or succeeds. Azimuth
Adjustment may fail to acquire the signal e.g. due to missing line of
sight such as a blocking zone, a structure in the harbor or the
landscape.

Note
It is strongly recommended to have Azimuth adjustment
enabled.
