Abstract
The theory of detection and repair of cycle-slip by combination of BeiDou triple-frequency observations has been described. The optimization principles of triple-frequency observations, and the threshold of cycle-slip, and the relationship between the STD and success rate of cycle-slip fixed have been discussed. In consideration of ionospheric delay, selecting the phase/pseudorange combination that is suitable for BeiDou triple-frequency and utilizing measured data to calculate the estimation of combined cycle-slip. Results show that the amount of STD of cycle-slip calculated by three-stage method is smaller than pseudorange/phase combination, ensuring the accuracy of cycle-slip detection and repair; and the workload of detection and repair of cycle-slip by three-stage method has been decreased compared with geometry-free phase combination.
