Study on the Processing Method of Cycle Slips under Kinematic Mode

Abstract

Through analyzing the DIA method, two step Kalman filter method and continuous cycle slips detecting method which is based on Kalman filter to deal with cycle slips, this paper proposes the improved method to deal with kinematic cycle slips which is also suitable to the high kinematic condition. By choosing “Current” statistic model to be the filter state model, this paper combines the carrier phase and Doppler observation to identify the cycle slip, meanwhile estimates and corrects the slip immediately. The result of calculating and analyzing the different simulated situation shows that the algorithm can better withstand the influence of maneuvering errors. As to the problem of multiple cycle slips and successive cycle slips, the algorithm can also deal with it fast and correctly.
