GPS Enabled
Walking or driving very slowly may also substantially reduce GPS performance.
Even where location information can be calculated in such situations, it may take much longer to do so, and your location estimate may not be as accurate.
Even where adequate signals from multiple satellites are available, your GPS feature will only provide an approximate location, often within 150 feet (45 meters) but sometimes much further from your actual location. Advice on how to improve GPS performance is provided in “Enhancing GPS Performance” on page 77.
While the GPS feature of your handset can be a valuable navigational aid, it does not replace the need for careful navigating and good judgment.
Never rely solely on one device for navigation. Remember that the accuracy of the location information and the time needed to obtain it will vary depending on circumstances, particularly the ability to receive signals from adequate numbers of satellites.
The satellites used by the GPS feature of your handset are controlled by the U.S. government and are subject to changes implemented in accordance with the Department of Defense GPS user policy and the Federal Radionavigation Plan. These changes may affect the performance of the GPS feature of your handset.
Viewing Your Approximate Location
1From the main menu, select GPS > Position.
2Scroll to view the entire screen.
This displays the following information about the last time your location was calculated:
•The time (as Greenwich Mean Time) and date that the location was last calculated
•The approximate location, expressed as latitude and longitude
•The estimated accuracy of the calculated location. This estimate of accuracy is only a very rough estimate and may vary substantially from the actual accuracy of the approximate location information reported.
•The number of satellites used to calculate the location. In general, more satellites make for better accuracy.
