[0030] According to a kind of embodiment of the present invention, adopt dual-frequency correlation method (references: Sun Hongxing, Li Deren. Use dual-frequency correlation method single epoch to solve GPS whole week ambiguity value [J]. Surveying and Mapping Journal, 2003, 32 (3 ): 208-212.)) and direct calculation method (references: Wang Xinzhou, Hua Xianghong, Qiu Lei. A new method for solving the ambiguity of the whole circle in GPS deformation monitoring [J]. Journal of Wuhan University (Information Science Edition) , 2007, 32(1):24-26.) Rapid determination of single-epoch double-difference integer fuzzy parameters by combination of algorithms.
[0031] According to an embodiment of the present invention, the method for quickly determining single-epoch double-difference integer fuzzy parameters by combining the dual-frequency correlation method and the direct calculation method is as follows.
[0032] First, the navigation satellites of each observation epoch are scree...
