The topside ionization over Indian region: An analysis using tomograms from Radio Beacon for Ionospheric Tomography (RaBIT) onboard YOUTHSAT

Understanding the electron density distribution of ionosphere is very important for the estimation of propagation delays involved in the satellite to ground communication systems and their corrections.The vertical electron density profiles of ionosphere have been extensively studied using the ionosonde in the early days. By nature of the principle of operation, Ionosonde can give profiles only up to F region peak altitudes. Hence the region beyond the F- peak referred to as topside ionosphere was not extensively profiled.
