Abstract:Based on fundamentals of cycle slip detection and correction through triple-frequency code-phase and geometry-free phase combination, we analyze the rate of electron content (TECR) in ionospheric activity phase. We then present a new triple-frequency method of cycle slip detection and correction for weakening the ionospheric error. The algorithm is validated by triple-frequency observed data in ionospheric activity phase, and the experimental results show that the method can detect and validlyrepair all the cycle slip in observed data in ionospheric activity phases. Moreover, the threshold of cycle slip detection on method is small and the method has no sensitive cycle slip.
