| 摘 要： | 基于三频观测值组合原理,在周跳探测与修复过程中提出了一种新的组合方法,即利用一组伪距/相位组合,一组无几何组合以及一组系数之和为1的几何组合,通过历元间差分,分步求取周跳估值。实验证明,该方法无不敏感周跳,并能够实时有效探测并修复周跳。

| Abstract: | Based on the principle of triple-frequency carrier phase combination,this paper puts forward a new method in cycle-slip detection and reparation,which uses pseudo-range and phase combination,whose coefficient is(0,-1,1),then uses a geometry-free phase combination(1,4,-5) and a geometric phase combination(4,-2,-3). Through the differential combination observations between epochs,the estimated value of cycle-slip is calculated.The method is proved by experiments and there is no insensitive cycle-slip,and it can effectively detect and repair the cycle-slip in real-time. |
