TEC analysis of IRI simulated data Original Research Article

The evaluation of Total Electron Content from Differential Delay data requires proper programs, which have been set up at IROE to process measurements from Navy Navigation Satellite System and Global Positioning System. Problems inherent to this analysis are: phase ambiguities and unknown hardware delays, the mapping function used to estimate vertical Total Electron Content from the slant one, and, for Global Positioning System only, the plasmaspheric content. The use of a “truth” ionosphere, as the one provided by International Reference Ionosphere, enables the production of artificial data. The Total Electron Content obtained processing these data can be compared with the “truth” Total Electron Content, helping in insulating the various problems, to give a deeper insight into the modeling of the analysis.
