Satellite Selection
BGAN service across the globe is covered by three of Inmarsat’s “I4”
satellites namely, I-4 Americas , I-4 EMEA and I-4 Asia Pacific .
“Satellite Selection” in an option in the Satlink FB250 terminal,
which allows user to select his/her preferred satellite for terminal op-
eration. The terminal is set to “Auto” satellite selection mode by de-
fault, which is the recommended mode of operation. In “Auto” mode,
the terminal will scan the sky and then registered to any one of the
satellite that is visible and gives better elevation angle. If the user man-
ually selects one of the 3 satellites, then the terminal will be forced to
lock to that selected satellite if it is visible. If it is not visible, the user
will be given a warning. If the user still proceeds to select the invisi-
ble satellite, then the terminal will continue to search for this particu-
lar satellite for ever until the selected satellite becomes visible,
regardless of other visible satellites. Switching from one satellite to an-
other satellite will force the existing active calls (CS and PS) to dis-
connect.
When in “Auto” mode, when the vessel is moving out of one satel-
lite and enters into another satellite’s coverage area, then terminal will
lose its connection with the first satellite and will reacquire and regis-
ter with the new satellite in coverage. During this satellite changeover
process, all existing voice/fax calls and data connections will be dis-
connected. Please take note.
