GPS and maps
The Global Positioning System (GPS) is a worldwide
radio navigation system that includes 24 satellites and
their ground stations that monitor the operation of the
satellites. Your device has an internal GPS receiver.
Note: The accuracy of location data can be affected by poor
satellite geometry. Availability and quality of GPS signals may
be affected by your location, buildings, natural obstacles, and
weather conditions. The GPS receiver should only be used
outdoors to allow reception of GPS signals. The first fix takes
several minutes.
The GPS receiver is located at the
top of the device. When using
the receiver, from an upright
position, move the device to an
angle of about 45 degrees with an
unobstructed view of the sky.
GPS
Your device also supports Assisted GPS (A-GPS) (network
service). A-GPS is used to retrieve assistance data over a
packet data connection, which assists in calculating the
coordinates of your current location when your device is
receiving signals from satellites.
Note: Any 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
or navigation.
With Maps, you can find your current location on the map,
browse maps for different cities and countries, search for
addresses, plan routes and navigate to your destination.
The map coverage varies by country. To open the Maps
application, press , and select Maps.
When you open Maps, it zooms in to the location that was
saved from your last session.

Note: Almost all digital cartography is inaccurate and incomplete
to some extent. Never rely solely on the cartography that you
download for use in this device.
