GPS在高铁控制测量中的精度分析——以西成高铁为例
|
摘要
介绍了GPS应用于高铁控制测量并进行精度分析的方法,利用GPS接收机所采集的数据,选用三差模型法进行数据解算,并采用现阶段国内外新方法进行精度分析,通过多种手段对数据进行综合处理,使得控制网成果的各项精度指标满足要求。由于解算精度与过程各有差异,针对高铁GPS控制测量中存在的问题,结合西成高铁工程实例进行数据处理分析,总结网型结构与GPS定位精度的联系,进而得出精度良好、成果可靠、较为经济的GPS网型,为工程实践提供理论指导。
This paper introduces the method of GPS applied to high speed railway control survey and accuracy analysis.Using the data collected by the GPS receiver,the three difference model method is used to solve the data.With the new method at home and abroad,the precision analysis is carried out at the present stage,and the data are processed by a variety of means,which makes the precision indexes of the control net results meet the requirements. Because of the difference between the accuracy and the process of the calculation,this paper deals with the problems in the high speed iron GPS control measurement and the analysis of the data processing with the example of the Xi'an-Chengdu high speed rail project. The connection between the network structure and the positioning accuracy of GPS is summarized,and then the GPS net with good precision,reliable results and more economical is provided,which provides theoretical guidance for engineering practice.
