摘　　要：为获取准确无误的载波相位观测数据,必须对载波相位观测中出现的周跳现象进行及时有效的探测与修复。文中分别对高次差分法及双频载波相位求差法进行研究仿真,针对高次差分法对大周跳探测稳定、相位求差法对小周跳探测敏感的各自特点提出将两者相组合的形式进行周跳的探测与修复,介绍了其设施方法步骤,最后利用算例验证了组合方法的可靠性和有效性。In order to obtain the accurate carrier phase observation data, it is necessary to detection and repair cycle slip appear in the carTier phase observation timely and effectively. Research on high difference method and double frequency carrier phase difference method and simulation respectively, in view of the high difference method to large cycle slip detection stability and phase for difference method for small cycle slip detection sensitive characteristics put forward the combined both the form of cycle slip detecting and repairing, and introduces the steps of the facilities. Finally, use an example verified the reliability and effectiveness of the combination method.
