11-2 General system information
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 detects the position of the vehicle by
utilizing the principle of triangulation.
Positioning adjustment
When the system judges that the vehicle
position information 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 satel-
lites
The reception of GPS signals can be weak,
depending on the environment. Vehicles in the
following areas/environments may not receive
GPS signals (indicator color: gray).
* Inside tunnels or parking garages
* Areas with numerous tall buildings
* Under multi-layered highways
* Under many large trees
