The existing triple-frequency cycle-slip detection method usually can not detect and repair the cycle-slip correctly in the ionospheric activity phase or when the magnetic storm happening. To solve the problem, the triple-frequency TurboEdit method for weakening the ionospheric error is advanced based on the dual-frequency TurboEdit method. Both the triple-frequency geometry-free and ionospheric-free combination and second-order time-difference phase geometry-free combination in this algorithm can whittle the influence of ionospheric error effectively. And then, the triple-frequency data is used to validate this algorithm, the experiment results show that this method can weaken the ionospheric error and realize the no-difference dynamicreal-time cycle-slip detection and correction under ionospheric activity phase. ©, 2015, SinoMaps Press.
