GPS data is designed to provide route guidance information to a selected destination,
position information about your current location, and travelling information, such as
the approximate distance to the destination and the approximate duration of travel.

The coordinates in the GPS are expressed using the international WGS-84 coordinate
system.
To use GPS data, the GPS receiver of your device must initially receive position
information from at least four satellites to calculate your location. When the initial
calculation has been made, it may be possible to continue calculating your location with
three satellites. However, the accuracy is generally better when more satellites are
found.
