| 摘 要： | 高效精确的周跳探测与修复算法是实现高精度导航定位的前提条件。鉴于常规算法易受到电离层影响,本文利用一个三频无几何无电离层码相组合和两个无几何相位组合构建周跳检验量,该周跳检验量能够有效地强电离层活动对周跳探测的影响。通过三频GNSS实测数据对本文算法的正确性和有效性进行验证,计算结果表明本文算法能够在强电离层活动下正确地实现周跳的探测与修复。

| Abstract: | Efficient and accurate cycle slip detection and repair algorithm is the precondition of realizing high precision navigation and positioning. Because of the fact that the conventional methods are easily affected by ionosphere activity, one triple-frequency geometry-free and ionosphere-free code-phase combination and two geometry-free phase combinations are used to construct cycle slip test which can effectively weaken the influence of strong ionosphere activity in this paper. The correctness and effectiveness of this algorithm are verified by the GNSS triple-frequency measured data. The results show that this algorithm can correctly detect and repair cycle slip under the strong ionosphere activity. |
