Abstract An algorithm of real-time detecting and correcting cycle slips for Precise Point Positioning (PPP) is presented. Based on dual-frequency pseudorange and carrier-phase observations, the algorithm can be used for static positioning and dynamic navigation under vigorous ionosphere activity. In order to ensure real-time capability and veracity, data processing and signal processing are combined and a method of reasonableness verification is presented to lower the probability of misjudge. A practical application is also presented to prove the applicability of the algorithm in strong ionospheric influence.
