Tomografía estocástica de la distribución de electrones ionosféricos.

Abstract

We present two techniques of stochastic tomography of the ionosphere, useful for the study of its electron density distribution. The basic observables are the differential delays experienced by two signals emitted by a member of the Global Navigation Satellite System constellations collected by receivers onboard Low Earth Orbiter satellites. Wc discuss dic Abel transform approach as a two-dimensional tomographic technique useful when che spherical symnietry assumption holds, and a more general four-dimensional tomographic approach. Finally, we apply diese analysis tools to data collected onboard the Danish satellite Oersted.
