摘　　要：针对三频无几何相位组合难以实时修复周跳的问题,采用两个无几何相位组合和一个三频伪距/载波组合联立方程组修复周跳的方法,并采用搜索法克服方程解不稳定的问题。最后利用北斗实测三频数据对整个算法进行验证,结果表明本方法能够实现动态、非差周跳的实时探测与修复。The triple-frequency geometry-free phase combination has a difficulty in real-time cycle-slips repairing, an equation system have been adopted to quantify cycle-slips, which are combined by two triple-frequency geometry- free phase combinations and a pseudo-range minus phase linear combination. A searching method has been used to solve ill-posed problem of the equation system. Finally, BeiDou triple-frequency data have been used to validate the whole algorithm, and the experiment result indicates that this method can be used in the dynamic, undifferential cycle-slips real-time detection and correction.
