The term navigation is generally understood to mean the

location of a vehicle, the determination of the direction and

distance from the desired destination and the required route. As

navigation aids, stars, prominent landmarks, compass and sat-

ellites are used.

This unit, location is determined with the GPS receiver (GPS

=Global Positioning System). The direction and distance from the

destination are determined by using a digital road map, a

navigation computer and sensors. A speedometer signal and a

reverse signal are additionally used to calculate the route.

The Global Positioning System (GPS) uses a network of satellites

orbiting the Earth. Each of the satellites, which orbit at a height of

68 900 000 feet (21 000 km), continually broadcasts radio signals

giving time and position information. This ensures that signals

from at least three can be picked up from any open area on the

earth’s surface.

The accuracy of the GPS information depends on how good the

reception is. When the signals are strong and reception is good,

GPS can determine latitude, longitude, and altitude for accurate

positioning in three dimensions. But if signal quality is poor, only

two dimensions, latitude and longitude, can be obtained and

positioning errors are somewhat greater.
