Comparison of polar ionospheric behavior at Arctic and Antarctic regions for improved satellite-based positioning
Abstract In this paper, we investigate the hemispheric symmetric and asymmetric characteristics of ionospheric total electron content (TEC) and its dependency on the interplanetary magnetic field (IMF) in the northern and southern polar ionosphere. The changes in amplitude and phase scintillation ar...
