Full skyscan -> Position antenna -> Step tracking -> Ready
Permanent loss of signal
Permanent loss of signal
If the Capsat® Telephone loses the signal permanently it will start a
reacquisition skyscan. For setting of the permanent loss of signal
time-out, see the section "Sync Lost Tm" in chapter "Menu System".

Description of the various scan algorithm
Full skyscan
Full skyscan
The full skyscan searches the whole sky (0-360 degrees in azimuth, 0-
90 degrees in elevation) for the best signal from the satellite
belonging to the Area/Ocean Region currently selected. The
message "Full skyscan - started" will be displayed in the handset.
One channel (one frequency) is used at a time.
If no signal is found during the first full scan the next channel
(frequency) belonging to the selected Area/Ocean Region is used for
the next full scan etc.
If however a signal is found during the full scan a signal threshold
level based on the best received signal is stored in the Capsat®
Telephone together with the azimuth and elevation angles of the best
received signal. The Capsat® Telephone will now position the
maritime antenna to these azimuth and elevation angles and follow
the description mentioned at power on.
Please note that if a full skyscan has been made with success once it
is not performed anymore unless
•
the Area/Ocean Region is changed
•
the signal is lost or below the signal threshold level for a very long
time (app. 15 minutes).
