Travelling
Need directions? Looking for a restaurant? Your device
has the tools to get you where you want to be.
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 Global Positioning System
(GPS) is operated by the
government of the United
States, which is solely
responsible for its accura
cy and maintenance. The
accuracy of location da
ta 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 obstacle
s, 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 shou
ld never rely solely on
location data from the GPS
receiver and cellular radio
networks for positioning or navigation.
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 da
ta
over a packet data connection, which assists in
calculating the coordinates of your current location
when your device is receiv
ing 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
