Abstract

The concept of UKIS is revised, illustrated graphically and represented by mathematical equations. Five
cities have been chosen for this study: Khartoum, Wadihalfa, Nimule, Kassala and AlJunaynah. The concept of twin
ionospheric links is introduced and different parameters for Twin links were studied. The relation between Twin links
and UKIS is illustrated. Contour maps that show the strength and death time of UKIS for the country are attached to
the paper. The study is based on empirical ionospheric modeling and the statistics are computed using the
International Reference Ionosphere model (IRI).
