Abstract
Aiming at the problem of cycle-slip detection and repair, the ultra-wide lane combination is used to assist the pseudo-distance phase combination in order to detect and repair cycle-slip because of its characteristics of weak noise and weak ionosphere in this paper. In order to remove the influence of insensitivity cycle-slip, the optimal combination coefficient is obtained according the numerical analysis results and the ill-posed equation has been avoided by using the minimum 2-norm as condition. The BeiDou triple-frequency measured data has been processed by this algorithm. These results show that this algorithm can effectively detect and repair all cycle-slip including different sizes and insensitive ones.
