| Abstract: | A comprehensive method for detecting and repairing cycle slips is proposed with single point positioning in single frequency receiver. The object of processes is data of difference carrier phase between two stars. Polynomial fitting and carrier phase rate are utilized in this method. The mathematical model of two methods are introduced in this paper, and then the concrete implementation steps are presented. The reliability and validity of the method are testified by an example. |
