Enhancing GPS Performance
Sometimes the GPS feature of your BlackBerry device may be unable to complete a location calculation successfully. If this happens when you are trying to view your location on the device's display, you will see a message indicating that your device cannot access satellites.
To improve accuracy and increase your chances of a successful calculation, do the following:
•Stay in the open
•Extend your BlackBerry device antenna
•Hold your BlackBerry device to enhance reception
•Stand still
•If you are stopped in your car, position your BlackBerry device near a window
•Stay in network coverage.
IMPORTANT: Things to Keep in Mind
The availability, accuracy, and the amount of time that it takes to calculate your location will vary depending on the environment in which you are using the GPS feature. For example, GPS location fixes are often difficult to obtain indoors, in covered locations, between high buildings, or in other situations where you have not established a clear broad view of the sky.
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. Therefore, in any 911 call, always report the location to the emergency response center if you can and if you cannot, remain on the phone call for as long as the emergency response center instructs you.
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 “Your GPS Location When Dialing 911” on page 47.
