Computerized Ionospheric Tomography (CIT) is a method to investigate ionospheric electron density in two or three dimensions. CIT provides a flexible method for studying ionosphere. In CIT, GPS satellites and Earth based receivers are considered to perform tomographic reconstruction. The received signals are processed to calculate Total Electron Content (TEC). TEC values and the tomographic reconstruction algorithms are used together to obtain tomographic images of electron density of ionosphere. In this study, scenario with one GPS satellite and one receiver is simulated. Receiver error and model error are neglected. In simulation, a set of basis functions and algorithms are used and two dimensional tomographic images of ionospheric electron density in height and latitude is obtained. Comparative reconstruction results are given based on IRI-95 forward ionosphere model. © 2005 IEEE.
