Now your navigation software Mobile Navigator can guide you to your destination quickly and reliably - without leafing through maps. The American military developed the Global Positioning System (GPS) in the 70s to be used as a guided weapons system. GPS is based on a total of 24 satellites that circle the earth. They constantly transmit their position and time. The GPS receiver tracks this data and calculates its own geographical position based on the different position and time data broadcast by the various satellites. Data from at least three satellites is required to indicate position with a sufficient degree of accuracy. The altitude above sea level can also be determined if data from 4 or more satellites can be obtained. The position can be indicated within 3 meters. The position can be used as a starting point for calculating a route after Mobile Navigator has determined your position. Your navigation device maps contain the geographical coordinates for points of interest, streets, and cities that are digitally acquired. This allows the navigation device to calculate a route from a given starting point to a given destination. The calculation and depiction of the current position on the map is repeated every second. In this way you can always see where you are moving on the map. 2.2 Important safety instructions It is in your own best interest to carefully read the following safety instructions and warnings before starting your navigation system. 2.2.1 Safety instructions for navigation The navigation system is used at the users own risk.

How your navigation system works
2.1
How your navigation system works
The days of searching for the correct route through thick folding
maps are over. Now your navigation software
Mobile Navigator
can guide you to your destination quickly and reliably – without
leafing through maps.
The American military developed the

(GPS) in the 70s to be used as a guided weapons system.
GPS is based on a total of 24 satellites that circle the earth. They
constantly transmit their position and time. The GPS receiver
tracks this data and calculates its own geographical position
based on the different position and time data broadcast by the
various satellites.
Data from at least three satellites is required to indicate position
with a sufficient degree of accuracy. The altitude above sea level
can also be determined if data from 4 or more satellites can be
obtained. The position can be indicated within 3 meters.
The position can be used as a starting point for calculating a
route after
Mobile Navigator
has determined your position.
Your navigation device maps contain the geographical
coordinates for points of interest, streets, and cities that are
digitally acquired. This allows the navigation device to calculate a
route from a given starting point to a given destination.
The calculation and depiction of the current position on the map
is repeated every second. In this way you can always see where
you are moving on the map.
