About GPS and satellite
signals
The Global Positioning System (GPS) is a worldwide radio
navigation system that includes 24 satellites and their
ground stations that monitor the operation of the satellites.
Your device has an internal GPS receiver.
A GPS terminal receives low-power radio signals from the
satellites and measures the travel time of the signals. From
the travel time, the GPS receiver can calculate its location to
the accuracy of metres.
The coordinates in the GPS are expressed in 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 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.
To enable or disable different positioning methods, such as
Bluetooth GPS, select Menu > Tools > Settings >
General > Positioning > Positioning methods.
About satellite signals
If your device cannot find the satellite signal, consider the
following:
• If you are indoors, go outdoors to receive a better signal.
