摘要：
To get high precise low earth orbiter (LEO) satellite orbit from satellite-borne GPS data, the satellite-borne GPS carrier phase measurements must be used, but there were still remnant cycle-slips after GPS data pre-processing. Least Square was an optimal method to solve parameters if the residual obeyed to normal distribution, but it was difficult to process data with systematic error, LP estimation was an effective method to process data with systematic error, LP estimation was applied to estimate satellite-borne GPS data in LEO satellite precise orbit determination in this paper. It is showed that LP estimation is more effective than that of LS to process GPS phase carrier with systematic error, and improve the LEO satellite orbit precision.
