【摘要】:針對(duì)電離層活躍期現(xiàn)有三頻周跳處理方法難以正確探測(cè)與修復(fù)周跳和閾值設(shè)定不合理的問(wèn)題,借鑒雙頻TECR算法,提出一種能夠削弱電離層延遲影響的三頻TECR算法。三頻TECR組合與三頻碼相無(wú)幾何無(wú)電離層組合均能有效削弱電離層延遲對(duì)周跳探測(cè)的影響,并能自適應(yīng)地確定合理閾值。利用三頻實(shí)測(cè)數(shù)據(jù)對(duì)算法進(jìn)行驗(yàn)證的結(jié)果表明,該方法能夠有效消除電離層延遲影響,實(shí)現(xiàn)電離層活躍期周跳的動(dòng)態(tài)探測(cè)與修復(fù)。
[Abstract]:Aiming at the problem that it is difficult to correctly detect and repair the cycle slip and the unreasonable threshold setting by the existing three-frequency cycle slip processing method in active ionospheric period, a three-frequency TECR algorithm which can weaken the influence of ionospheric delay is proposed by referring to the dual-frequency TECR algorithm. Tri-frequency TECR combination and tri-frequency code phase-free geometric ionosphere-free combination can effectively weaken the influence of ionospheric delay on cycle slip detection and can adaptively determine the reasonable threshold. The results show that the method can effectively eliminate the influence of ionospheric delay and realize the dynamic detection and repair of the cycle slip in the active period of the ionosphere.
