STPIR和MW组合的北斗三频周跳探测与修复
A Combination of STPIR and MW for BDS Triple-frequency Cycle Slip Detection and Repair
摘要
Abstract
Focusing on the problem of cycle slips occurred in phase observation and the situation of triplefrequency signal broadcasted by BDS,the triple-frequency second-order time-difference phase ionosphere residual (STPIR) algorithm is introduced.The algorithm is not influenced by the observation interval.Blind spots can be avoided with the use of combining with MW for cycle slip detecting and repairing.Both of them attenuate the effect of ionospheric delay.Cycle slips can be decided directly with float value rounding to the nearest integer and the effect of ionospheric delay is attenuated by both combined observations.BDS triple-frequency data has been used to validate the algorithm,and the experimental result indicates that the method proposed in this paper can effectively detect and repair all cycle-slip even in the large observation interval.关键词
