摘要
研究了三频周跳探测与修复的常用算法——伪距/载波相位组合法和MW-无几何相位组合法,给出了两种方法的探测阈值。利用北斗三频实测数据,分析了不同采样间隔下,单频点发生周跳和多频点同时发生周跳时,两种方法的周跳探测与修复效果。结果表明,在实际观测中,采样间隔设置为小于10 s更为有利,且采用MW-无几何相位组合法可以更有效地对周跳进行探测与修复。
The normal triple-frequency cycle-slip detection and repair algorithms, pseudorange/carrier phase combination and MW ＆ Geometry-free combination, are studied. The detection threshold is given. Using Compass triple-frequency real data, with different sampling intervals, the detection effects of the two methods are analyzed in cases of cycle slips occurring on a single frequency and multiple frequencies. The results have shown that in the process of observation, the sampling interval should be set smaller than 10s which is more beneficial. And the MW-Geometry-free combination is usually more effective.
