GPS Location Services
It may take your terminal several minutes to complete the
process of determining your location. During this time, a
message usually appears on your terminal’s display stating:
• Insufficient Visible Satellites, or
• Insufficient Visible Data
For tips on getting the best location calculation, see
“Enhancing GPS Performance” on page 62.
The Position screen displays the updated information.
To cancel a location calculation before it is completed:
Press Back to return to the previous screen.
Each time approximate location of your terminal is
calculated, the latest location information is stored in your
terminal and remains there even when your terminal is
powered off. You will see this information the next time you
view the Position screen.
If you received a terminal call or alert while attempting to
determine your location, the Position screen will disappear,
but your terminal will continue attempting to determine its
location. If it is successful, the new location information will
be displayed the next time you view the Position screen.

Satellite Almanac Data
Government officials maintains an almanac of data about
where GPS satellites are as they orbit the Earth. This
information is available to your terminal. Keeping your
satellite almanac up to date helps your terminal determine
your location more quickly.
The almanac contains information about the location of
satellites, their operational status, and other satellite
information.
