12. Positioning (GPS)

You can use applications such as Maps and GPS data to find out your location or
measure distances and coordinates. These applications require a GPS connection.

About GPS

The coordinates in the GPS are expressed in the degrees and decimal degrees format
using the international WGS-84 coordinate system.
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. The
GPS receiver should only be used outdoors to allow reception of GPS signals.
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.
To enable or disable different positioning methods, select Menu > Applications >
Location and Positioning > Positioning methods.

Assisted GPS (A-GPS)

Your device also supports Assisted GPS (A-GPS).
A-GPS is a network service.
Assisted GPS (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.
