针对常规模糊度检验三步法中存在的错误模糊度整数解漏检的情况,分析了错误整周模糊度、观测值残差及多余观测分量矩阵之间的内在联系,阐述了参考星变化对多余观测分量矩阵主对角线元素的影响,进而提出了一种基于多余观测分量的整周模糊度可靠性检验方法。该方法根据多余观测分量主对角线占优原则实现部分卫星的模糊度可靠性检验。对于多余观测分量主对角线不占优的卫星,利用多余观测分量绝对值最大的情况进行整周模糊度可靠性检验,从而完成所有卫星的模糊度可靠性检验。
Aiming at the situation of the integer ambiguity detection of fuzziness ambiguity in the three-step method of conventional ambiguity testing, this paper analyzes the inherent relations between the error integer ambiguity, the observed residuals and the extra observational component matrices. The influence of the main diagonal elements of the extra observational component matrix, and then puts forward a method of testing the reliability of the integer ambiguity based on the extra observational component. The method verifies the reliability of the ambiguity of some satellites based on the dominant diagonal of the extra observational component. For satellites whose main diagonals of redundant observation components are not dominant, the reliability of integer weeks ambiguity test is tested by using the maximum absolute value of redundant observation components, so as to complete the ambiguity reliability test of all satellites.
