Development of Satellite Based Sensor for Unambiguous Retrieval of Ionospheric Data in Conjunction with Ground Based Receivers

Abstract

Accurate descriptions of electron density distributions in the ionosphere and the meteorological condition in the troposphere, covering most of the entire globe is needed for various operational, technical and scientific purposes. Measurements of integrated electron densities using transmissions from GPS, NNSS or other beacon satellites can be used to retrieve the height distribution of electron densities over wide regions of interest. CRS has developed the most comprehensive software for such retrieval. Extensive simulations have been performed and we have demonstrated that neither ground based receivers, nor satellite based receivers alone are capable of fully recovering the ionospheric profiles with reasonable accuracies. Satellite based receivers, in conjunction with ground based receivers, however, can provide the desired ionospheric informations, even for the bottomside lower ionosphere.
