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.
You must have an internet access point defined in the
device to retrieve assistance data from the Nokia A-GPS
service over a packet data connection.
