摘要

摘要: 针对载波相位观测值中出现周跳的问题,将TurboEdit算法中的LG组合进行二次历元间差分(STPIR),差分结果可以很好地消除电离层延迟的趋势项影响,而且差分后的组合观测值不受观测数据采样间隔的影响,从而有利于周跳的探测。同时,利用MW组合与STPIR组合实现了周跳的探测与修复。对静态和动态观测数据进行处理的结果表明,将MW与STPIR组合可以更准确地探测与修复周跳。

Abstract: For problems of cycle slips occurred in phase observation,the second-order difference phaseionospheric residual(STPIR)algorithm is introduced.It can remove the trend component of iono-spheric variations effectively.The algorithm is not affected by the observation interval,so it benefitscycle slip detection.At the same time,the use of MW in combination with STPIR for cycle slip detec-ting and repairing is realized.In static and dynamic data processing,experimental results show thatthe combination of MW and STPIR is accurate for cycle slips detection and repair.
