ThurayaIP Satellite Modem User Guide 7
Quick Reference
This section serves as a reference guide, identifying the key operational
aspects of using the ThurayaIP system and the Controls and Indicators
on ThurayaIP and their functions.

Global Positioning System Operation

The ThurayaIP contains an integrated Global Positioning System (GPS)
receiver that is used to provide location information. GPS location
information is required for system access, and the reception of a new
GPS location is attempted automatically every time ThurayaIP is
powered on.
For optimum GPS signal reception, make sure ThurayaIP is positioned in
a roughly horizontal placement. 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 ThurayaIP 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, ThurayaIP 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 ThurayaIP 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
ThurayaIP to refresh the GPS receiver. Also, your stored GPS location
remains good for a period of time 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 ThurayaIP satellite
pointing operation prior to going directly onto the network. Be sure to
carefully point your unit every time it is moved.

STORED GPS LOCATION

The most recent GPS location is stored in ThurayaIP even when powered
down. Upon power up, the ThurayaIP will attempt to update this GPS
location since the Thuraya system will only allow access if your GPS
location is not too old. If ThurayaIP has a valid GPS location then the
GPS icon on the display will go from flashing to solid. Likewise, the web
MMI will indicate if the currently available GPS location is valid or invalid.
