Abstract
The ionospheric-induced error on dual-frequency GNSS navigation signals is exploited to quantify measurements of the ionosphere and create time-varying 2D ionospheric Total Electron Content (TEC) images over Southern Africa. TEC is a relevant space weather parameter and its application in space weather studies is demonstrated by investigating the ionospheric response to the November 2004 geomagnetic storm.
