发布时间：2018-11-16 06:59
【摘要】：针对电离层活跃期现有三频周跳处理方法难以正确探测与修复周跳和阈值设定不合理的问题,借鉴双频TECR算法,提出一种能够削弱电离层延迟影响的三频TECR算法。三频TECR组合与三频码相无几何无电离层组合均能有效削弱电离层延迟对周跳探测的影响,并能自适应地确定合理阈值。利用三频实测数据对算法进行验证的结果表明,该方法能够有效消除电离层延迟影响,实现电离层活跃期周跳的动态探测与修复。
[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.
