Aiming at the problem that the positioning accuracy of the rover station will decrease rapidly with the increase of the differential period when the differential data is interrupted in RTK measurement technology, and the centimeter-level position service cannot be provided. A continuation method of breakpoint based on single station is proposed. When the differential data of the rover is interrupted, the data of the rover will be processed through the double-difference model between epochs and satellites based on the broadcast ephemeris. In order to calculate the high-precision time baseline and then get the centimeter-level position of the rover station, the ionospheric error, tropospheric error, satellite clock error and orbit error are all corrected or estimated. In this paper, the method is verified by the static data and dynamic data. The experimental result shows that the positioning accuracy at plane can maintain at centimeter level within 10 min, which can effectively improve the reliability and continuity of RTK results in the scenarios of unstable differential data.
