GPS mode of operation
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 derive its current geographi-
cal position.
The positioning requires signals from
at least 3 satellites. Starting with the
fourth one, it is possible to also de-
termine height above mean sea level.
The positioning is carried out with an
accuracy to 3 metres.
Destination guidance with GPS. The
supplied map material also contains
the geographic coordinates of points
of interest, streets and cities that you
can view on the screen of the Lucca.
This allows the navigation system to
calculate a route from a starting point
to a place of destination.
