5. Tap the field Satellite . A new window is displayed. Tap and scroll to find the
wanted satellite, then tap on a satellite to select it. The list is sorted as
follows: 180°W -> 0° -> 180°E.
6. Configure the tracking properties.
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

Profile handling Default satellite in the list
Create new profile The satellite closest to the ship’s
position is highlighted.
Edit profile The satellite currently selected for
this profile is highlighted.
Note
At some longitudes, multiple satellites are co-located. In this case, it
is not important which 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.
1. For more information see e.g. www.lyngsat.com or www.satbeams.com. 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.
