Positioning (GPS) Positioning (GPS) You can use applications such as GPS data to find out your location, or measure distances and coordinates. These applications require a GPS connection. About GPS The trip meter has limited accuracy, and rounding errors may occur. Accuracy can also be affected by availability and quality of GPS signals. 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 Assisted GPS (A-GPS) 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 Your device also supports assisted GPS (A-GPS). A-GPS is requires network support. 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. 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. 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. GPS should not be used for precise location Your device is preconfigured to use the Nokia A-GPS measurement, and you should never rely solely on service, if no service provider-specific A-GPS settings 92 location data from the GPS receiver and cellular radio networks for positioning or navigation. are available. The assistance data is retrieved from the Nokia A-GPS service server only when needed.

Positioning (GPS)
You can use applications such as GPS data to find
out your location, or measure distances and
coordinates. These applications require 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 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. 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 accuracy, and rounding
errors may occur. Accuracy can also be affected by
availability and quality of GPS signals.
The coordinates in the GPS are expressed using the
international WGS-84 coordinate system. The
availability of the coordinates may vary by region.
Assisted GPS (A-GPS)
Your device also supports assisted GPS (A-GPS).
A-GPS is requires network support.
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.
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
are available. The assistance data is retrieved from
the Nokia A-GPS service server only when needed.
