摘　　要：针对TurboEdit方法中Geometry-Free(GF)组合拟合窗口、Melbourne-Wübbena(MW)组合中误差求取窗口过大造成小周跳探测不敏感的问题,通过对观测数据进行质量分析自适应设置GF组合和MW组合窗口,重新构造周跳检测量进行周跳探测,并利用搜索法解决修复失败历元的周跳修复问题。利用GPS和BDS实测双频数据对改进方法进行验证,实验结果表明本方法能准确探测到1周的小周跳,经搜索后周跳修复成功率提高至100%。The fitting window of Geometry-Free （GF） combination and the calculating window of RMS of Melbourne-Wubbena （MW） combination forTurboEdit are too large ,resulting in that small cycle slip detection is not sensitive.The method of analyzing the quality of observational data to adaptively set the window of GF combination and MW combination is adopted, detectable quantity to detect cycle slip is reconstructed, and a searching method is used to solve the problem of failure of repairing the cycle slip. GPS and BDS dual-frequency data are utilized to validate the algorithna.The experimental results show that the algorithm can accurately detect small cycle slip, and effectively improve the success rate of repairing cycle slip.
