ABOUT THE NAVIGATION SYSTEMThis navigation system combines the data ob-
tained 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 on the screen, allow-
ing route guidance to a destination.GPS is a system developed and operated by the
U.S. Government, covering the entire planet.
This navigation system receives three or more
different radio signals from NAVSTAR (GPS
satellites), orbiting the earth 13,049 miles
(21,000 km) above ground. The data from dif-
ferent sets of signals will be trigonometrically
calculated to obtain the position of the vehicle.
INFO:
The tracking center in the U.S. controls signals
transmitted from GPS satellites. This control
sometimes results in reduced accuracy or no
signal received at all in accordance with govern-
ment requirements.
ACCURACY OF POSITIONINGThe color of the GPS Indicator
on the upper
left corner of the screen indicates positioning as
follows:
Green: positioning is possible and accurate
Yellow: positioning is possible but accuracy
is minimal.
Gray: positioning is not possible
