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 coordinates in the GPS are expressed in the
degrees and decimal degrees format using the
international WGS-84 coordinate system. The
availability of the coordinates may vary by region.
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 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.
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
