Positioning (GPS)
You can use GPS data to find out your location or measure
distances. This requires a GPS connection.
About GPS
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
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. Avai
lability 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 a
ccuracy, 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 requires network support.
Assisted GPS (A-GPS) is used to retrieve assistance data
over a packet data connection
, which assists in calculating
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 provid
er-specific A-GPS settings are
available. The assistance data is retrieved from the Nokia
A-GPS service server
only when needed.
A-GPS is an internet service.
When using A-GPS, it may incur
data charges. For information about costs in your
home
network, contact your service provider.

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. The access point for
A-GPS can be defined in posit
ioning settings. Only a packet
data internet access point ca
