QUICK REFERENCE
This section serves as a reference guide, identifying the key operational aspects of using the
Regional BGAN system, the Controls and Indicators on the Satellite IP Modem and the functions
of the Launch Pad software.

PERATION
Your Satellite IP Modem contains an integrated Global Positioning System (GPS) receiver that is
used to provide location information to the Regional BGAN system. GPS location information is
required for system access and the reception of a new GPS location is attempted automatically
every time the Satellite IP Modem is powered on.
For optimum GPS signal reception, make sure the Satellite IP Modem is positioned in a roughly
horizontal placement with the lid closed. Since GPS receivers must “see” a large part of the sky
without obstructions from buildings, mountains or trees, it may be necessary to take your Satellite
IP Modem out to a clear space to obtain a new GPS location. It may be possible to obtain a
new GPS location in a less favourable circumstance, but the time to completion may be longer.
Once updated, the Satellite IP Modem remembers your location so the unit can be relocated to
a more convenient working area, such as inside a building by a window facing toward the
satellite.
Once you have established a session on the Regional BGAN system you will not need another
GPS location while you remain connected in the “Always On” condition. This is convenient if you
intend to operate from one location for an extended period of time since there is no need to
move the Satellite IP Modem to refresh the GPS receiver. Also, your stored GPS location remains
good for a period of time (consult with your service provider for this information) even if you
power down and move a short distance between sessions. When you believe this is the case,
simply skip the GPS location step and complete the Regional BGAN satellite pointing operation
prior to going directly onto the network. Be sure to carefully point your unit after every time it is
moved.
STORED GPS LOCATION
The most recent GPS location is stored in the Satellite IP Modem even when powered down.
Upon power up, if this stored GPS location is available the display indicates “Using Stored
Location.” Even so, the Satellite IP Modem will attempt to update this GPS location since the
Regional BGAN system will only allow access if your GPS location is not too old. If the Satellite IP
Modem is able to update the GPS location, the status changes from “Stored” to “Valid.” GPS
location is shown as “Invalid” only under special circumstances when the stored information has
been erased. In any case, you may wish to attempt network access to see if service will be
granted.
