| Abstract: | 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 s... |
