Abstract：This research examines cycle slip detection and repair theory of triple-frequency pseudo-range phase combination and geometry-free combination. Their thresholds are deduced, and the optimum selection method of combinations is investigated. Based on the smallest variance of combinations, and taking ionosphere delay errors during each epoch into consideration, these two combinations fit for BDS triple-frequency data are selected. Finally, BDS data is used in the experiment to validate these two algorithms. The result shows that these two algorithms can detect and repair all the simulated cycle slips in real-time. Taking amount of calculation, complexity and rounding error into account, pseudo-range phase combination is recommended.
