About the GPS Feature

Your BlackBerry device is equipped with a Global Positioning System 

(GPS) feature. This feature uses information from GPS satellites orbiting 

the earth to determine the approximate geographical location of your 

device (latitude and longitude). 
When you make a 911 emergency call, the GPS feature of your device 

can help emergency personnel locate you. Your device must have 

adequate access to GPS satellite signals and your emergency response 

center must be equipped to process such information.

When you make an emergency 911 call, the GPS feature of your device 

automatically begins to seek information to calculate your approximate 

location. It may take 30 seconds or more to determine the approximate 

location even if your device has good access to sufficient GPS satellite 

signals and network assist data. This time will increase where there is 

reduced access to satellite signals. When your approximate location is 

determined, it is made available to the appropriate emergency response 

center.
In some cases, your local 911 emergency response center may not 

be equipped to receive GPS location information. For this reason, 

and because the GPS location information reported is only approximate 

or may not be available in your location, always report your location to 

the 911 operator when making an emergency call.

Note: If you are concerned about whether your local 911 emergency 

response center is equipped to receive GPS location information, 

contact your local authorities using a non-emergency number.

In general, if your device has access to signals from more GPS satellites, 

your location will be determined faster and more accurately than if your 

device has access to signals from fewer GPS satellites.
If your device does not have adequate access to GPS satellites signals, 

the location of the nearest cell tower in contact with your device is 

automatically made available to the emergency response center.
