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. To use GPS, you need a compatible GPS receiver.
Use Bluetooth connectivity to connect to the GPS receiver.
To start using a compatible GPS receiver with Bluetooth
connectivity, select Connectivity > Bluetooth.
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.
To enable or disable different positioning methods, such
as Bluetooth GPS, select Menu > Tools > Settings >
General > Positioning > Positioning methods.
