| Abstract: | A new method is proposed for detecting and repairing cycle slips in GPS navigation based on the single frequency observations.Carrier phase rate is used to detect cycle slips, and record the starting time and the closing time of cycle slips.Then Chebyshev polynomial is used to repair cycle slips.The mathematical model of the method is introduced in this paper.The concrete implementation steps are presented.The reliability and validity of the method are testified by an example. |
