Positioning (GPS)

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

About GPS

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
or navigation.

The trip meter has limited accuracy, and rounding errors
may occur. Accuracy can also be affected by availability
and quality of GPS signals.
Different positioning methods can be enabled or disabled
in positioning settings.

Assisted GPS (A-GPS)

Your device also supports assisted GPS (A-GPS).
A-GPS is requires network support.
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.
When you activate A-GPS, your device receives useful
satellite information from an assistance data server over
the cellular network. With the help of assisted data, your
device can obtain the GPS position faster.
Your device is preconfigured to use the Nokia A-GPS
service, if no service provider-specific A-GPS settings are
available. The assistance data is retrieved from the Nokia
A-GPS service server only when needed.
