| 摘 要： | 针对BDS全星座播发三频信号的特点,利用1个三频载波伪距组合(1,4,-5)和2个三频无几何相位组合(1,1,-2)、(1,-2,1)联合的方法进行周跳探测,并结合最小2-范数确定整数周跳的搜索策略。实测数据表明,该方法对一般周跳、不敏感周跳及连续随机周跳均有较好的探测与修复效果。

| Abstract: | We are concerned with the characteristics of the triple-frequency signal broadcast by the full constellation of the Beidou navigation satellite system. One carrier pseudorange combination (1,4,-5) and two triple-frequency geometric-free phase combinations (1,1,-2) and (1,-2,1) perform the cycle slip detection. We combine the minimum 2-norm to the integer cycle-slip search strategy to determine the cycle-slip value. The measured data show that the proposed method can detect and repair the normal cycle-slip, insensitive cycle-slip and continuous random cycle-slip. |
