摘要

这种自动车辆定位系统是在澳大利亚开发和安装的,具有低成本的车载组件,并且在定位能力和准确性方面提供了高系统性能。在车辆之间传输数据的附加功能使车队管理和安全方面的许多应用得以实现。该系统的设计覆盖范围约为2000公里/平方公里,精度约为30米。它有能力支持许多独立用户和成千上万的车辆。目前的追踪能力是每小时追踪30000个地点。扩频相位倍增技术可在建筑物密集地区的多径环境中提供移动车辆的精确定位。

QUIKTRAK: a unique new AVL system
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.<>
