针对典型周跳探测与修复方法中的电离层残差法当同一历元多个频点发生周跳时，无法准确探测及修复周跳的问题，提出了一种用多普勒辅助电离层残差法的周跳探测与修复的改进方法。基于实测及仿真数据，证明了该方法能够有效解决电离层残差法存在的上述问题，即使某一历元多个频点同时发生周跳，也可以准确探测周跳发生的位置、频点及相应数值，精度达到1周，有效提高了电离层残差法探测与修复周跳的准确性与可靠性。

For the ionosphere residual error method of the typical cycle slip method w hich has the problem of not accurately detecting and repairing cycle slip w hen cycle slips of different frequency occur on the same epoch ,this paper put forward a kind of improved cycle slip detection and repair method of ionosphere residual error based on doppler aid .According to the measurement and simulation data ,it is proved that this improved method can effec-tively solve the problem of the ionosphere residual error method mentioned above . Even w hen cycle slips of different frequency occur on the same epoch ,it can accurately detect and repair the cycle slip low to one round ,thus improve the accuracy and reliability of cycle slip detection and repair .
