摘　　要：GPS载波相位测量中,周跳探测和修复是需要解决的关键问题之一。针对电离层残差法中检测量存在检测盲区问题,通过对误差的分析,引入了利用伪距约束构造辅助检测量的方法,给出了辅助检测量的表达式和阈值:先利用电离层残差法检测周跳,对检测结果显示无周跳的数据,再利用伪距约束构造辅助检测量检测周跳。实例分析表明:这种方法能够很好的解决电离层残差法检测不出一些特殊组合的周跳的问题,在静态测量数据中,能够检测并修复所有整数周跳。Detection and repairing of cycle GPS＇s measurements by carrier phase. In this slip is one of the key issues to be resolved in article, to solve the problem of existing detec- ting dead zone in detected cell in ionized layer remnant method of difference, introduce a method of constructing adjuvant detected cell by the restriction of range and expression and threshold , namely detect cycle slip by using ionized layer remnant method of difference first, then using the adjuvant detected cell if it shows no cycle slips. Examples show that this kind of method can solve the problem that it can＇t detect some cycle slips with particular combina- tion better and can detect and repair all integer cycle slips of the static observations.
