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 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.
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 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.
