    Effects of equatorial plasma bubble-induced ionospheric gradients on GNSS PPP-RTK

    Equatorial plasma bubble (EPB) exerts a severe threat to global navigation satellite system (GNSS) technique. It not only can lead to ionospheric scintillation, but also can create strong plasma gradients in i...

    Comparative study of ionospheric sporadic E occurrence rates using SNRnstd and S4 derived from GPS radio occultation

    GPS radio occultation (GPS-RO) data, especially the parameters of signal-to-noise ratio normalized standard deviation (SNRnstd) and S4, are widely used to measure the ionospheric sporadic E (Es) layer. However, t...

    Large-area tsunami signatures in ionosphere observed by GPS TEC after the 2011 Tohoku earthquake

    The internal gravity waves (IGWs) produced by a tsunami can travel into the ionosphere and trigger traveling ionospheric disturbances (TIDs). In this study, we report ionospheric measurements related to the hu...

    Analysis of geometry-free residuals in case of traveling ionosphere disturbances and their impact cycle slip detection

    We discuss the impact of a traveling ionospheric disturbance (TID) on cycle slip detection for the geometry-free (GF) combination. Based on the GF combination algorithm, we deduce for the first time the comput...
