The authors have developed a navigation system for automobiles that employs the locating signals broadcast by the NAVSTAR/GPS satellites. The system simultaneously detects signals from four satellites, enabling it to locate its host car's position to within 100m at any point on the earth's surface. The system consists of a GPS receiver, an antenna, a controller, a CD-ROM, a 6 inch CRT display, a speed sensor and a dead-reckoning geomagnetic sensor. The car's position is indicated on a map on the display screen, enabling the driver to easily reach his destination even in unfamiliar areas.
