Positioning (GPS)

Positioning (GPS)
You can use applications such as GPS
data to find out your location or
measure distances. 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 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
