By measuring the time required for a signal totravel between the satellites and the antenna. the cars location can be pinned down within l00 meter
4、s.The satellite signals. along with inputs on speed from a wheel-speed sensor and direction froma meter, determine the cars position even as it moves. This information is combined with amap database. Streets, landmarks and points of interest are included.Most systems are basically identical. The dif
5、ferences come in hardware-the way the computeraccepts the drivers request for directions and the way it presents the driving instructions.
