| Abstract: | According to the characteristic of the three-frequency signal and its combination observation, a new method on non-difference observation value for detecting and repairing cycle slip is presented in this paper. This method is based on the combination of ultra-wide lane and ionosphere residual method. The location and size of cycle slip are obtained by solving the phase observation value of the BDS three-frequency carrier phase. The calculation results show that the combined method can effectively detect and repair the different size cycle slip, and the apply to the signal processing of three different types of Beidou satellite. These illustrate that the algorithm has higher accuracy and reliability. |
