英文摘要： GNSS ambiguity resolution for single frequence is foundation of high presice positiong & attitude measurement. Due to the diffculty and using longer time of traditional search algorithm on GNSS ambiguity resolution, the method of rapid ambiguity resolution would be studied based on result zone & regularizer rule with the former works. Through establishing the model, inducing the search step and studying of check analysis method, the system info would be building and the realization method would be proposed about GNSS ambiguity resolution for single frequence based on result zone, then the theory and method of GNSS ambiguity resolutuin would be more self-contained. Through studying of the principle of regularizer algorithm, the intrinsic order of relations between characteristics of ill-condition observation matrix and observation epoch data would be opened up in substance, the problem of how to select improved regularizer matrix on principle and how to seek realization method would be resolved, and then the influence after adding improved regularizer matrix on searching parts of GNSS ambiguity resolution need to be deep-seated analyzed, also the feasible method to weaken the influence because of adding improved regularizer matrix need to be studied deeply too. A new principle would be explored at last to break t
