•
Beam Selection: The modem chooses the
best deemed beam available at current
location to be sent to the terminal using
OpenAMIP. The selection is done from one
of the preconfigured beams in the modem.
Current beam is shown in the home screen
as seen in Figure 23.
•
Beam Switch: If first assigned beam cannot
be accessed due to line of sight issues or
weak signal a beam switch can be initiated.
Done by a long press of the OK button. Dots
between terminal and globe will start to
flash. New satellite/ frequency settings will
have been acquired as flashing stops. Whereas the user can repoint the terminal and try to
acquire into the new suggested Satellite or Beam.
In a beam switch at the very least the beam will change depending on available beams and
available satellites at that location the beam switch might also change the satellite that the
terminal should be pointed at.
When multiple beams have been configured to the modem and at least two of those beams is
deemed by the modem to work in the current terminal location the following will happen.
•
In a first stage the user has 10 minutes to point the terminal. After the 10 minutes an
automatic beam switch will occur and change beam and/or satellite.
•
If the user cannot find the carrier at the current location either due to line of sight issues or
wants to run the terminal on a different beam/satellite a Beam switch can be requested from
the modem.
•
Beam switch is initiated by a long press on the OK button and acknowledging the following
pop-up.
•
If the user has locked onto a carrier and starts the terminal transmit the acquisition timers
starts (the default for many systems it is set to 45 seconds). Either the terminal is accepted
into the network or not.
•
If the terminal is not accepted after the 45 seconds another beam switch occurs where the
user is directed to point to a different beam.
Notes:
In some cases, there are multiple beams from the same satellite which overlaps, usually with high
throughput satellites. Sometimes the next beam in the modems beam map then is from the same
satellite on the same polarization but a different frequency. The user then does not have to change
anything as the frequency is changed automatically. Sometimes only the polarization change in
between the beams and sometimes also the satellite changes as well in a beam switch. Sometimes
after the terminal is not accepted (Can be due to the terminal is not commissioned on that beam, too
low C/N or other reasons) then if only frequency is changed the terminal will try to get into the
second beam without any user input.
