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.

OCATION
 
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.
