Positioning (GPS)

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

About GPS

The coordinates in the GPS are expressed 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. 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.
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.

About assisted GPS (A-GPS)

Your device supports A-GPS (network service). 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.
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.
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.
