Ionospheric Research Using Satellites.

Abstract

The report completes two Annual Scientific Reports (1969, 1970) on the study of the ionosphere using satellites. The ray tracing program used to study ionospheric effects on satellite signals is described in some detail and examples given. The accuracy of graphical methods usually used was found to be better than 7% in a difficult case and the results were not very sensitive to the medium altitude used. A method to detect the satellite's spin for the correction of Faraday data was developed. It is based on accurately determining the changes in the polarization parameters, using the Poincare sphere concept. The contribution of the TEC (Total Electron Content) and its gradients to errors in a satellite navigation system (NNSS) were determined. These depend on the geometry of the pass relative to the station. Computed results are shown graphically and the results are interpreted. (Author)
