Vertical total electron content performance of EGNOS and locally adapted NeQuick 2 model

This paper describes EGNOS and NeQuick 2 model vertical Total Electron Content performance on three stations in the Eastern Europe. Two 6-day periods with different ionospheric conditions were observed. Values calibrated by Ciraolo method were used as a reference. NeQuick 2 model was driven by ingestion of reference data at one of the stations and its modeling degradation with distance was observed. Both EGNOS and NeQuick 2 provided good estimation of the ionosphere in the observed periods.
