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 in degrees
and decimal degrees format 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 the coordinates of your location.
When the initial calculation has been made, it may be
possible to continue calculating the coordinates of
your location with three satellites. However, the
accuracy is generally better when more satellites are
