WHA T IS A NA VIGA TION
SYSTEM?
ABOUT THE NAVIGATION SYS-
TEM
This navigation system combines the data ob-
tained from the vehicle (by gyro sensor) and
from GPS (Global Positioning System) satel-
lites to calculate the current location of the ve-
hicle. This position is then displayed on the
screen, allowing route guidance to a destina-
tion.
WHA T IS GPS (GLOBAL PO-
SITIONING SYSTEM)?
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 NAVST AR (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 gov-
ernment requirements.
ACCURACY OF POSITIONING
The color of the GPS Indicatoron the up-
per left corner of the screen indicates position-
ing as follows:
Green: Positioning is possible and accurate
Y ellow: Positioning is possible but accu-
racy is minimal.
Gray: Positioning is not possible
