摘　　要：针对电离层活跃期或磁暴发生时,现有三频周跳探测方法难以正确探测与修复周跳的问题,借鉴双频TurboEdit思想,提出了能够削弱电离层延迟影响的三频TurboEdit方法。该算法中的三频无几何无电离层码相组合和两次历元差分后的相位无几何组合,均能有效削弱电离层延迟对周跳探测的影响。随后利用三频实测数据对本文算法进行了验证,试验结果表明该方法能够消除电离层延迟影响,实现电离层活跃观测条件下动态非差周跳的实时探测与修复。The existing triple-frequency cycle-slip detection method usually can not detect and repair the cycle-slip correctly in the ionospheric activity phase or when the magnetic storm happening. To solve the problem, the triple-frequency TurboEdit method for weakening the ionospheric error is advanced based on the dual-frequency TurboEdit method. Both the triple-frequency geometry-free and ionospheric-free combination and second-order time-difference phase geometry-free combination in this algorithm can whittle the influence of ionospheric error effectively. And then, the triple-frequency data is used to validate this algorithm,the experiment results show that this method can weaken the ionospheric error and realize the no-difference dynamicreal-time cycle-slip detection and correction under ionospheric activitv Phase.
