| 摘 要： | 在目前常用的周跳探测与修复方法基础上 ,提出了首先将观测资料按照观测历元不连续分成若干小弧段 ,然后利用差分法进行周跳探测 ,根据差分后周跳放大的特性判断周跳和野值 ,并确定其位置利用宽带组合和电离层组合的方法解算周跳大小。通过实例验证了其有效性。

| Abstract: | On the basis of current methods of cycle-slip detection and correction, a new method was discussed in this paper. Firstly, we divided the observation arc into some sub-arcs according to the discontinuous epochs and detected the cycle-slip by means of differential method, judging cycle-slip or outliers by the character of the amplification of the cycle-slip after difference and determining their location, then both the wide-lane combination and the ionosphere-free combination were used to detect and correct the cycle-slip. An example was taken to prove the validness of the method. |
