  By Okonkwo Perpetua, Ugwuanyi Joseph

  Abstract: Diurnal and day-to-day variations of vertical total electron content (VTEC) over an equatorial region (Ilorin, Nigeria; geographic 8.50°N, 4.55°E; geomagnetic 10.60°N, 78.41°E) is presented in this paper using data from the IRI model and from the AFRL-SCINDA (Air Force Research Laboratory – Scintillation Network Decision Aid) GPS receiver installed at the Ilorin station. A comparison between VTEC data from the two sources is also presented since a major concern in …
