Ionospheric monitoring using GNSS data from LEO satellites for space weather applications: (additional thesis)

In this report, a least-squares approach is described for retrieving the 3D structure of the electron concentration in the Earth’s upper ionosphere and plasmasphere, using Global Navigation Satellite System (GNSS) data-sets from Low-Earth-Orbiting (LEO) satellites. Due to the lack of horizontal radio wave geometries, the method uses assumptions...
