| Abstract: | In real-time mode, some kinds of error corrections for GPS pseudo-rang are given in the paper, i.e. tropospheric refraction delay, ionospheric refraction delay, earth-rotating correction, relativity effect, satellite antenna eccentricity, solid tide correction. Based on experiments of single frequency point positioning, each way of correction has been analysed in this paper. Finally,give out the accuracy of point positioning. |
