WHAT IS A NAVIGATION SYSTEM?
ABOUT THE NAVIGATION SYSTEM
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 on the screen, allowing route guidance to a destination.
WHAT IS GPS (GLOBAL POSITIONING 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 NAVSTAR (GPS satellites), orbiting the earth 13,049 miles (21,000 km) above ground. The data from different 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 government requirements.
ACCURACY OF POSITIONING
The color of the GPS Indicator on the upper left corner of the screen indicates positioning as follows:
¼ Green: Positioning is possible and accurate
¼ Yellow: Positioning is possible but accuracy is minimal.
¼ Gray: Positioning is not possible
