Quantifying the relationship between ionospheric ionization levels and GNSS positioning errors: insights from Global Ionospheric Maps

This thesis investigates the relationship between ionospheric ionization levels and GNSS positioning errors, focusing on data from the ALEX2 station between 2013 and 2019. Us ing single- and dual-frequency Precise Point Positioning (PPP), ENU positioning errors were analyzed in correlation with iono...

Us ing single- and dual-frequency Precise Point Positioning (PPP), ENU positioning errors were analyzed in correlation with ionospheric Total Electron Content (VTEC) derived from Global Ionospheric Maps (GIMs) and geomagnetic indices (Kp, ap).
