Search algorithm for Land Mobile antenna
Search algorithm for Land Mobile antenna
The search algorithm controls the land mobile antenna and gives a
quick and reliable tracking of the Area/Ocean Region selected.
Power On
Power On
At power on the land mobile antenna will make some internal
initialisation before it is ready for use (a few seconds).
NOTE:
The land mobile antenna may NOT be turned within the first 5
seconds after power on because these 5 seconds are used for gyro
adjustments.
After the land mobile antenna becomes ready the Capsat®
Telephone will check the current position of the land mobile antenna.
If a valid signal above the stored signal threshold level is found at the
current position the land mobile antenna is commanded into step
tracking. After a few seconds the normal message e.g. "AORE:ST12"
will be displayed in the handset meaning that the Capsat® Telephone
is now ready for calls.
During the idle period where no activity is made on the Capsat®
Telephone the signal threshold level will be stored with regular
intervals in the Capsat® Telephone and used at next power on.
If above conditions are not fulfilled the Capsat® Telephone will start a
reacquisition skyscan.
NOTE:
During the first reacquisition skyscan after power on the gyro will not
compensate for any movements of the land mobile antenna. The land
mobile antenna will scan the sky with a fixed scan rate (degrees pr.
second) relative to the surface where the antenna is mounted. After
60 seconds in step tracking the gyro will come in effect.
