摘要
分析了影响单基站差分GPS测量的主要误差因素,研究了不同基线长情况下广播星历、电离层和对流层延迟等误差对单基站差分GPS数据精度的影响程度及规律,通过设立双基站测量、与精密单点定位软件处理比较等方法检验了单基站差分GPS数据精度,得出了在用单基站差分GPS测量系统满足一定精度要求的结论。
The main error factors which affect the single-reference station DGPS surveying is analyied in this paper, and the degree and law that single-reference station DGPS data precision is affected with the errors of broadcast ephemeris is studied, ionospheric and tropospheric delays under different distance between base station and GPS user. The single-reference station DGPS data precision is tested by means of comparing the data processed with precise point positioning softsurv and measured with double-reference station DGPS. The conclusion is drawn that the data precision of the actual range GPS survey system fulfils the requirement of range precision.
