The invention discloses a method for jointly detecting and repairing a cycle slip by an MW combination method and a non-geometric phase method. The method comprises the following steps of S1, selecting three-frequency data (B1, B2 and B3) of a Beidou navigation and positioning system to obtain a pseudo-range observation value and a carrier phase observation value; S2, constructing a three-frequency MW combined observation model, establishing a MW equation, and carrying out inter-epoch difference to obtain cycle slip detection amount delta N12 and delta N13; S3, constructing a non-geometric phase observation model; S4, selecting two groups of parameters according to a principle that an ionized layer coefficient and the observation noise of the combined observation data are relatively smallat the same time, calculating the cycle slip of the three frequency points of the two groups of the parameters according to a formula that delta N1 is equal to delta N2 that is equal to delta N3, andselecting a B combination
