The Global Positioning System (GPS) 
was developed in the 70s by the US 
military.
GPS is based on a total of 24 satel-
lites that are orbiting the earth and 
sending out signals. The GPS receiver 
receives these signals and calculates 
its distance to the individual satel-
lites using the propagation time of 
the signals. This information is then 
used to determine its current geo-
graphical position.
The positioning requires signals from 
at least three satellites, and starting 
with the fourth one it is also possible 
to determine the altitude above sea 
level. The positioning is carried out 
with an accuracy to 3 metres.
Navigation with GPS. The provided 
maps also contain the geographical 
coordinates of the displayed points 
of interest, streets and towns. This 
allows the navigation system to cal-
culate a route from a starting point to 
a place of destination.
