This paper has proposed a trigonometric fitting and extrapolating method of detecting the single-frequency receiver′s cycle-slip and offered the coefficient formula of trigonometric fitting coeffi-cient for the procedure of using the method to detect a cycle-slip and the quantification formula for it . The performances of the method are compared with those of the traditional polynomial fitting and ex -trapolating method in terms of the fitting and extrapolating accuracy and the length of the data win -dow .Through a simulated cycle-slip experiment ,the new method is proved to be capable of detecting a cycle-slip down to half cycle .
