| Abstract: | Firstly,the production of cycle slips and common methods for detecting and repairing cycle slips are briefly shown;then the paper uses two different ways phase difference between sequential epoch and Doppler to detect and correct cycle slips,and the result illuminates that two ways both not only can exactly lock the epoch having cycle slips,but also can repair the carrier phase value efficiently.Two methods have high practicality and efficiency,especially for kinematic GPS positioning such as RTK. |
