AGPS & Emergency Calls
When you make an emergency call, your mobile device can use Assisted Global
AGPS & Emergency Calls
Positioning System (AGPS) satellite signals to tell the emergency response center
your approximate location.
The AGPS feature has limitations, so always tell the emergency response center
your best knowledge of your location. Remain on the phone for as long as the
emergency response center instructs you.
AGPS might not work for emergency calls, if your local emergency response center
does not process AGPS location information. For details, contact your local
authorities.
If your mobile device cannot find strong AGPS satellite signals, the location of the
nearest cell tower in contact with your mobile device is automatically provided to
the emergency response center.
AGPS Performance Tips
• Go outside and away from underground locations, covered vehicles, structures
with metal or concrete roofs, tall buildings, and foliage. Indoor performance
might improve if you move closer to windows, but some window sun shielding
films can block satellite signals.
• Move away from radios, entertainment equipment, and other electronic devices
that might interfere with or block AGPS satellite signals.
AGPS uses satellites controlled by the U.S. government and subject to changes
implemented in accordance with the Department of Defense AGPS user policy and
the Federal Radio Navigation Plan. These changes might affect AGPS performance.
