摘要
在城镇外业测量中,由于受地形和通讯条件的限制,现有RTK技术不能很好发挥作用,普通静态测量观测时间效率低,采用双基准站快速静态可以很好弥补其他GPS作业模式的不足。本文介绍了GPS快速静态定位的几种作业方式及原理,并采用双基准站作业方式进行工程实测数据的检核比较,分析了数据质量的参考指标,表明了其良好几何精度和数据可靠性,体现了双基准站GPS快速静态定位的作业效率和实用性特点。
In the outdoor work of survey in cities and towns, due to the limits of terrain conditions and communica- tion condition, the present RTK technology can not fully function . The normal static measurement is not efficient in ob- serving time. Using the double base stations fast static measurement can well compensate for the lack of other GPS work- ing model. This paper introduced a few operation methods and principle in GPS fast static positioning,the double base stations fast static summary originally the text GPS the rapid static state positions of,and compared these methods to the double basis station way. After analysis the reference index of the data identity, the new method is proved to have a good geometry accuracy and data reliability which gave expression to the efficiency and function characteristics of GPS fast static positioning.
