摘　　要：周跳探测与修复是GNSS实时精密定位的必要前提之一。基于北斗三频载波相位观测值线性组合理论基础,提出了一种新的周跳探测与修复的方法,该方法采用三组线性无关的线性组合,分别为:超宽巷EWL(0,-1,1),超宽巷EWL(1,4,-5),窄巷NL(1,0,0),通过三组不同采样间隔(1s,10s,30s)北斗三频实测数据分析,表明了该方法的可行性,可以正确的实时探测和修复所有模拟周跳值,且该方法也适合低采用率的数据。Cycle slip detection and repair is a necessary prerequisite for real-time GNSS precise positioning. Based on BDS triple-frequency linear combination of carrier phase obser- vations theoretical, we propose a new cycle slip detection and repair methods. The method u- ses three sets of linear independent combinations observation, namely： extra-wide lane EWL （0,--1,1）, extra-wide laneEWL （1,4,--5）, narrow lane NL （1,0,0）. Through three dif- ferent sampling intervals （1s, 10s, 30s） BDS triple-frequency measured data analysis showed that： the method is feasible, and the method can correctly real-time detection and repair cycle slips value, and the method is also suitable for the low adoption rate of the data.
