| Abstract: | The detection and repair of cycle slips play an important role in the processing of GPS data. So far, various methods exist and are rather mature. Several common ways of detecting are introduced in this paper and repairing cycle slips, particularly describes the ionoshperic remnant method of difference and its multi--valued problem. Then puts forward a effective method to solve the multi--valued problem. The test results proved the effectiveness of this new method. |
