AGPS Limitations and
Tips
Your phone uses assisted-Global Positioning
System (AGPS) satellite signals to estimate
your location. If your phone cannot find strong
satellite signals, your AGPS might be slower,
less accurate, or it might not work at all. AGPS
provides only an approximate location, often
within 150 feet (45 meters) but sometimes
much farther from your actual location.
To improve AGPS accuracy:
• 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.
46 Setting Up Your Phone
• Move away from radios, entertainment
equipment, and other electronic
devices that might interfere with or
block AGPS satellite signals.
• Extend your phone antenna.
• Hold your phone away from your body,
and point the phone antenna toward
the sky Do not cover the antenna area
with your fingers
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.
