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.
