Satellite Coverage Map; Antenna Pointing - Nera Saturn BM Marine Operator's Manual

Antenna Pointing

General
The antenna is highly directive and must be pointed accurately at the
satellite to achieve optimum receiving and transmitting conditions.
During normal operation the antenna is kept pointed at the satellite by
the auto-tracking system of Saturn Bm.
However, before the auto-tracking can take over, the antenna must
be brought within a certain angle of the satellite.
For manual pointing, the following data must be available:
Ship's Plotted Position
The plotted position is
needed to decide which
satellite can be used. See
Satellite Coverage Map in
appendix A.
Example:
Ship's Heading
The ship's heading is needed to give
correct azimuth reading in the Display
Handset.
