Abstract	The paper completed all the correction of constellation error and receiver channel error. It was brought forward a comprehensive scheme for position error correction. The experiment platform was based on Superstar II GPS receiver and Matlab. It mainly corrected the position error such as satellite clock error, ionospheric error, tropospheric error, the earth rotation effect etc. Moreover, ionospheric delay error was corrected for about 14 m by Klobuchar model; tropospheric error was corrected for the average value of 4.05 m by the altitude angle module and so on. Especially, the satellite clock error was corrected for 3.1 m related to IGS by empirical formula. The user clock error is the max error with magnitude of $10^{4}~10^{5}$ s to affect position result. Finally, these methods improved the positioning precision to 17 m. The result of experiment has proved the validity of these correcting methods, accumulating much experience for the next investigation.
