receiver receives this data and calculates its own geographical position
on the basis of the information transmitted by the various satellites.
Data from at least three satellites is required for positioning with an
acceptable degree of accuracy. With data from four or more satellites it
is possible in addition to determine the position's altitude above sea
level. Positioning is accurate to within three metres.
Once the navigation device has determined your position, this position
can be used as a starting point for calculating a route.
The map data on your navigation device includes the geographical
coordinates of all digitally recorded points of interest, streets and
places. This enables the device to calculate a route between a starting
point and a destination.
Calculation of the current position and its representation on the map
takes place once every second. In other words, your current position is
always shown on the map.
