GPS技术在道路观测中的应用

The Application of the GPS Technology in the Observation and Survey

介绍了道路断面测量的基本要求,比较了GPS技术和全站仪测量方法的利弊,详细介绍了GPS测量的转换参数解算和动态GPS测量的误差。介绍了一个GPS测量的实例。是后提出了应用GPS技术应注意的事项。

This paper introduces the basic requirement on the section measuring of the road. It compares the advantages and shortcomings between the GPS technology and the traditional surveying methods. Then it introduces in detail the calculation of the transferring parameter by GPS surveying, the errors in the GPS surveying and an example of GPS surveying, At last it puts forward a few items which should be paid attention to in the surveying by GPS.
