ABOUT THE NAVIGATION SYSTEM
This 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 differ-
ent sets of signals are trigonometrically calcu-
lated 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. Consequently, areas such as
military bases may not accurately appear on the
navigation screen.
ACCURACY OF POSITIONING
The color of the GPS Indicatoron the upper
left corner of the screen indicates positioning as
follows:
cGreen: positioning is possible and accurate
cYellow: positioning is possible but accuracy is
minimal
cGray: positioning is not possible
INFO:
For approximately 3 or 4 minutes after system
startup, the GPS indicator
remains gray,
even if accurate positioning is possible.
