| Abstract: | Since GPS single point pseudo-ranging can fast get results without the ambiguity resolution,it has great application value.This paper gives out the influence on positioning by tropospheric refraction delay,ionospheric refraction delay,earth rotating correction and relativity effect,introduces two ways to get receiver clock error,and discusses how to get geodetic coordinate and Gauss horizontal coordinate of receiver. |

| Keywords: | GPS single point pseudo-range numerical derivative receiver clock error geodetic coordinate Gauss horizontal coordinate |
