摘要
The ambiguity free model of precise pointing can eliminate the ambiguity parameter, because the method of Epoch-difference of phase is used. The estimation parameters of this model are the position difference. Based on the robust estimation, this paper discusses the analyses the effects of the sample interval on the results of position-difference. The characterization of position-difference error is studied using wavelet analysis. According to the characterization of errors, some key problems that happen using the method of Epoch-difference to position are also studied.
