How Does A Car Navigation
System Works ?
The
computer in your navigation system uses signals transmitted from
the Global Positioning System (GPS) satellites orbiting the path
to determine the exact position of the car at any time, day or
night, regardless of your location.
The integrated gyro (electronic compass) and electronic speedometer
supply additional data which the system uses to calculate and
monitor your route. Simply
enter your desired destination and the system ease you through
the traffic with the aid of an icon or map display and spoken
instructions in a pleasant male or female voice.
If you do happen to take a wrong turn, the system reacts immediately
to guide you safely back on course.
The
system also uses of Traffic Message Channel (TMC). The Traffic
Messaqe Channel (TMC) is a standardised system of broadcastinq
constantly updated traffic information (about accidents and
hold-ups,
for instance). Sensors on motorways and roads measure traffic
density and transfer this information to centralised traffic
computers.
Additional data such as direction and speed of traffic flow make
it possible to predict conqestion.
TMC receivers can filter data according to direction of traffic
flow, qeoqraphical area or class of road, enablinq drivers to
qain a personalised selection of traffic information at the push
of a button. The navigation system can also use TMC data to calculate
an alternative route around an obstruction
