提出了一种基于码相组合和无几何相组合的罗盘三频载波相位数据的实时周跳检测与修复方法。首先，我们将低电离层的额外宽车道码相组合作为第一和第二周差可探测量，将低电离层的无几何相位组合作为第三周差可探测量，从而组成三个线性独立的组合。然后，以最小2范数作为循环滑动修复原则，搜索和匹配循环滑动估值的最小二乘解的循环滑动组合。最后利用不同采样率和不同类型卫星的观测数据进行了周滑检测与修复实验。结果表明，在不存在不敏感周跳组合的情况下，对不同采样率和不同类型卫星观测数据的任何周跳组合的检测和修复都是准确和实时性的。
This paper presents real-time cycle-slip detection and repairs for compass triple-frequency carrier phase data with code-phase combination and geometry-free phase combination.Firstly,we use the extra wide-lane code-phase combinations with low ionosphere as the first and second cycle-slip detectable amount,geometry-free phase combination with low ionosphere as the third detectable amount,thus composing three linearly independent combinations.Then we search and match cycle-slip combinations of least squares solutions of cycle-slip valuations by taking minimum 2norm as the cycle-slip repair principle.At last we use observation data of different sampling rates and different type satellites to conduct cycle-slip detection and repair experiment.The result shows that it is accurate and real-time to detect and repair any cycle-slip combination of observation data in different sampling rates and type satellites as well as there is no existing insensitive cycle-slip combination.
