2. Enter or edit the Satellite profile name.
3. Select a satellite from the drop down list. This list contains the TV
satellites known to the system. If needed, you can add a TV
satellite, see
4. Configure the tracking type.
Automatic
:
The system will automatically determine which signal to track on,
based on an automatic frequency and transponder scan of the
satellite.
If the vessel moves out of coverage of the transponder currently
being tracked, the system will initiate a new frequency and
transponder scan and find another transponder to track, on the
same satellite (assuming the vessel is still in coverage of the
satellite).
• Polarisation: Select Linear or Circular depending on the
polarisation with which your provider transmits the TV
signals

.
Note
It is helpful to assign a name containing the location where the Satellite
profile is to be used (e.g. "Gulf of Mexico" or "North Sea") and possibly the
provider.
Note
At some longitudes, multiple satellites are co-located. In this case, it is not
important which satellite is chosen, as long as the longitude is correct. The
chosen satellite will be the one the system tracks, but it will receive and
forward the TV signals from all the co-located satellites
Note
During frequency and transponder scan, TV reception is possible. Thus,
Automatic tracking is not slower than manually configured tracking parameters.

Linear signals are marked with the letter H for Horizontal or V for Vertical.
Circular signals are marked with either L for Left hand or R for Right hand.
Note
Selecting Linear when the TV signal is transmitted with Circular polarisation,
or vice versa, results in a 3 dB loss in signal strength. Hence, this setting
cannot be verified by presence of TV signal alone. Often however, it will not
be possible to receive and track the TV signals using the wrong polarisation.
