针对北斗三号载波相位观测值的周跳现象影响定时、定位精度的问题，联合MW(Melbourne-Wbbena)和STPIR(second-order time difference phase ionosphere residual)组合提出了一种探测和修复北斗三号载波相位周跳的方法。该方法不受信号采样间隔影响，且能够有效弥补单一组合具有的周跳探测盲区的缺陷，解决单一组合的周跳修复多值性问题。基于本文方法，对北斗三号五种民用信号B1C、B1I、B2a、B2b、B3I载波相位观测值进行了验证，结果表明，联合MW和STPIR组合可以准确探测和修复北斗三号五种信号载波相位周跳。
Abstract：Aiming at the problem that the cycle slip of Beidou-3 carrier phase observation seriously affects the precision of timing and positioning, a method to detect and repair Beidou-3 cycle slip is proposed by combination of MW and STPIR. This method is not affected by the signal sampling interval, and can effectively make up for the defect of cycle slip detection blind area of a single combination, and solve the multivalued problem of cycle slip repair of a single combination. Based on this method, experiments are carried out with the Beidou-3's carrier phase observations of B1C, B1I, B2a, B2b and B3I civil signals. The experimental results show that the combination of MW and STPIR can detect and repair the carrier phase cycle slip of Beidou-3 accurately.
