GENERAL INFORMATION FOR
NAVIGATION SYSTEM
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 Sys-
tem)?
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 triangulation.
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 auto-
matically 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 highways
