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:
•

•

Extend your BlackBerry device antenna

•

•

•

If you are stopped in your car, position your BlackBerry device 

•

Stay in network coverage.

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.
