| 摘 要： | 传统码相组合算法能探测7～8周以上大周跳,而传统的电离层残差法仅对于±4周以内的周跳可实现唯一分离,这限制了两者组合的应用.针对这一问题,对码相组合探测与修复周跳方法进行改进,使得改进的码相组合与电离层残差法能够完全探测周跳.经理论与实验分析,组合改进的码相组合法与电离层残差法两者结合能够完全探测采样间隔小于10 s观测数据中的周跳,对动态非差观测值数据的周跳自动探测与修复有极佳的效果.

| Abstract: | Traditional code-phase combination algorithms can detect seven to eight cycle slips or more,while the traditional ionosphere residual method can only separate 4 cycle slips,which limits the application to combining two methods.In order to solve this problem,the code-phase combination to detect and repair cycle slips is improved.The theoretical and experimental analysis shows that combination of the improved code-phase combination and ionosphere residual method could detect and repair cycle slips of less than 10s from the observation samples and indicates the great effect on detecting and repairing cycle slips of dynamic zero-difference observation data. |
