Automatic Satellite Searching
The Saturn Bm offers two types of automatically started searches:
Initial Search performed when:
• turning on power
• restarting the equipment, or
• Ocean Region changed by user.
Auto Search performed when:
• synchronization with the satellite has been missing for more than a
preset timeout. The factory default time is 10 minutes.
For presetting of the timeout period (0 . . 1440 minutes), see

Search Patterns
Azimuth Search
A 360° rotation of the antenna in azimuth at a fixed elevation angle.
Hemispheric Search
A hemispheric search is made out of azimuth
sweeps at elevation angles 10°, 20°, 30°, 40°,
50°, 60° and 70°.
The antenna searches on the
active channel frequency (NCSC).
For more information, see
"Antenna
"Satellite
chapter 4. System.
When finding the satellite
signal, it completes the
hemispheric search and
moves to the position where
the strongest signal was de-
tected.
The antenna then tracks the
satellite automatically.
If no signal is detected, no further automatic action occurs until an
Auto Search is activated due to the preset missing synchronization
timeout, see above.
