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。
針對電離層活躍期或磁暴髮生時，現有三頻週跳探測方法難以正確探測與脩複週跳的問題，藉鑒雙頻 TurboEdit 思想，提齣瞭能夠削弱電離層延遲影響的三頻 TurboEdit 方法。該算法中的三頻無幾何無電離層碼相組閤和兩次歷元差分後的相位無幾何組閤，均能有效削弱電離層延遲對週跳探測的影響。隨後利用三頻實測數據對本文算法進行瞭驗證，試驗結果錶明該方法能夠消除電離層延遲影響，實現電離層活躍觀測條件下動態非差週跳的實時探測與脩複。

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 activity phase.
