Abstract
GNSS cycle slip is one of the important factors affecting the reliability of monitoring results, and it is particularly crucial to accurately detect and repair the size of each frequency cycle slip. In response to the coefficient uncertainty problem of existing triple frequency combination cycle slip detection methods, this paper proposes global search method for triple frequency joint calculation of cycle slip based on the geometry-free observation equation, using single P-code observation values instead of triple frequency pseudorange to form a triple frequency cycle slip sequence and constrain its value range. The results of 1 Hz sampling data processing show that the method proposed in this paper can effectively solve the problem of cycle slip position and multi-value, with a detection success rate of over 98% and a false detection rate of less than 3%.
