Initial skyscan
Initial skyscan
The initial skyscan searches the sky (0-360 degrees in azimuth, 0-90
degrees in elevation) for the first signal from the satellite belonging
to the Area/Ocean Region currently selected. The message "Init
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 which is above the signal threshold level
the Capsat® Telephone will command the antenna into step tracking
and follow the description mentioned at power on.
Reacquisition skyscan
Reacquisition skyscan
The reacquisition skyscan searches a part of the sky for the first
signal from the satellite belonging to the Area/Ocean Region
currently selected. A part of the sky may be 360 degrees turn in
azimuth with fixed elevation angle or a circle of 20-30 degrees
around the current azimuth/elevation position. The message "Re.
skyscan - started" will be displayed in the handset.
If no signal is found within app. 15 minutes a full skyscan will be
performed.
If however a signal is found which is above the signal threshold level
the Capsat® Telephone will command the antenna into step tracking
and follow the description mentioned at power on.
Step tracking
Step tracking
The step tracking fine-tunes the antenna position towards the
satellite. The message "Step track. - started" will be displayed in the
handset. The Capsat® Telephone sends continuous signal information
to the maritime antenna. The step tracking will takes place also when
making calls although the update rate will be slower.
