基于GPS单点定位的工程测量技术研究

Research on Engineering Measurement Technique Based on GPS Single Point Positioning

以GPS单点定位在城市工程测量中的应用为研究对象,探讨了BERNESE 5.0软件数据处理流程、IGS精密星历等关键技术。在此基础上,结合案例进行分析,结果表明精密单点定位完全满足城市工程测量的日常需要。

Based on the work experience in the city engineering survey for many years, this paper researches on city engineering sur- vey application and examines the BERNESE 5.0 software data processing flow, the key technologies of the IGS precise ephemeris. On this basis, the author carries out the analysis combining the ease and the results show that the precision of a single point positioning fully meets the needs of measurement by the urban engineering.
