摘　　要：分析了TurboEdit方法的局限性,提出了一种改进方法。该方法联合差分无电离层观测值(DLC)、电离层观测值(LG)和Moulborne-Wuebbena宽波模糊度观测值(MW)综合探测和确认周跳。对多个IGS站的处理结果表明,改进方法能够有效地剔除观测噪声造成的虚假周跳,从而增强了数据的连续性和参数估计程序的计算效率。The cycle slip detection approach TurboEdit which is developed for single GPS station data is briefly reviewed and its shortcomings are analyzed.In order to overcome these shortages,a new approach is presented based on Turboedit.In the new approach,satellite-differenced ionosphere-free phase observations（DLC）,ionospheric observations（LG） and Moulborne-Wuebbena observations are used together for cycle slip detection.The approach is validated with data from IGS stations,the results show that the improved approach can effectively avoid the wrong decision on unrealistic cycle slips in the original approach caused by observation noises.This improvement increases the data continuity and reduces the computation burden of the data processing software.
