GENERAL INFORMATION
CURRENT VEHICLE LOCATION
Display of current vehicle location
This navigation system combines the data
obtained from the vehicle (by gyro sensor)
and from GPS (Global Positioning System)
satellites to calculate the current location of
the vehicle. This position is then displayed
throughout route guidance to a destination.
What is GPS (Global Positioning
System)?
GPS is a position detecting system that uses
satellites deployed by the U.S. government.
This navigation system receives radio signals
from three or more different satellites that
orbit 13,049 miles (21,000 km) above the
earth in space, and detect the position of the
vehicle by utilizing the principle of triangula-
tion.
Positioning adjustment:
When the system judges that the vehicle
position is not accurate based on vehicle
speed and gyro sensor data calculations, the
system will automatically adjust the position
of the vehicle icon using GPS signals. Receiving signals from GPS satellites:
The reception of GPS signals can be weak,
depending on the environment. Vehicles in
the following areas/environments may not
receive GPS signals.
* Inside tunnels or parking garages
*In areas with numerous tall buildings
*Under multi-layered freeways
*Areas with numerous tall trees
