Maps and GPS
Once the internal GPS receiver in your device locates a satellite signal, it may take several
minutes for the device to display the current location.
The Global Positioning System (GPS) is operated by the government of the United States,
which is solely responsible for its accuracy and maintenance. The accuracy of location
data can be affected by adjustments to GPS satellites made by the United States
government and is subject to change with the United States Department of Defense civil
GPS policy and the Federal Radionavigation Plan. Accuracy can also be affected by poor
satellite geometry. Availability and quality of GPS signals may be affected by your
location, buildings, natural obstacles, and weather conditions. GPS signals may not be
available inside buildings or underground and may be impaired by materials such as
concrete and metal.
GPS should not be used for precise location measurement, and you should never rely
solely on location data from the GPS receiver and cellular radio networks for positioning
