This automatic vehicle location system developed and installed in Australia features a low-cost on-vehicle component, and offers high system performance in terms of location capacity and accuracy. The added ability to transfer data to and from the vehicle enables many applications in fleet management and security to be realized. The system has been designed to provide coverage over an area of some 2000 km/sup 2/ with an accuracy of approximately 30 m. It has the capability to support many independent users and many thousands of vehicles. The current tracking capacity is 30000 locations per hour. Spread-spectrum phase-multilateration techniques provide accurate locations on moving vehicles in the severe multipath environment encountered in heavily built-up areas.<>
