Signals from Global Positioning Satellites (GPS) were used to investigate the ionospheric dynamics along the 17.5 degree East meridian between Cape Town and Northern Namibia. Ionospheric total electron content (TEC) measurements calculated from GPS receivers located at Cape Town, Springbok, Keetmanshoop, Windhoek and Tsumeb served to investigate the diurnal, seasonal and latitudinal variation along the meridian during quiet and geomagnetic disturbed days of 2011. Results were compared with the International Reference Ionosphere (IRI) model. GPS-derived TEC measurements confirmed theoretical expectations but supplied revealed finer ionospheric structure not attainable by theoretical models.
