The evaluation of the TEC from differential delay data requires proper programs, which have been set up at IROE to process measuremenets 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 TEC from the slant one, and, for GPS only, the plasmaspheric content. The use of the "truth" ionosphere, as the one provided by IRI, enables the production of artificial data. The TEC obtained processing these data can be compared with the "truth" TEC, helping in insulating the various problems to give a deeper insight into the modelling of the analysis.

Abstract
The evaluation of the TEC from differential delay data requires proper programs, which have been set up at IROE to process measuremenets 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 TEC from the slant one, and, for GPS only, the plasmaspheric content. The use of the "truth" ionosphere, as the one provided by IRI, enables the production of artificial data. The TEC obtained processing these data can be compared with the "truth" TEC, helping in insulating the various problems to give a deeper insight into the modelling of the analysis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
