Even where location information can be
calculated in such situations, it may take more
time than usual, and your location estimate
may not be as accurate.
Even where adequate signals from multiple
satellites are available, your AGPS feature will
provide only an approximate location, often
within 150 feet (45 meters) but sometimes
much farther from your actual location.
The satellites used by your phone's AGPS
feature are controlled by the U.S. government
and are subject to changes implemented in
accordance with the Department of Defense
AGPS user policy and the Federal Radio
Navigation Plan. These changes may affect
the performance of your phone's AGPS
feature.
