摘　　要：针对单独使用电离层残差组合法或M-W组合法对双频GPS载波数据进行周跳探测的局限性,研究了将这两种方法联合对双频GPS数据进行周跳探测的方法和数学模型,实验计算表明:联合方法比只使用其中一种方法能更有效的进行周跳探测与修复。According to the shortcomings of singlely using ionosphere residual combination method or MW combination method to detect cycle slip for dual-frequency GPS data,the method and mathmatical models which is used to cyde slip detection for dual frequency GPS data by the combination of the two methods is reserched. The experimental caculation shows that using the combined method is more effective to detect and repair the cycle slip than only using one of them.
