Abstract

The plasma sheath can potentially degrade electromagnetic systems through signal attenuation as well as increased amplitude and phase fluctuation. Utilizing electron density and collision frequency provided by NASA, transmission coefficient is calculated by the scattering matrix method and phase fluctuation is obtained. By means of Electromagnetic propagation theory and GPS software receiver, the effects of phase fluctuation by plasma sheath on GPS signal and its positioning are analyzed. Results show that the maximal percentage of variation larger than 5m is up to 14%.
