Outline of Final Research Achievements

Ionospheric disturbances, which are caused by solar flares and magnetic storms, have an effect on satellite-based communication, broadcasting and GPS positioning accuracy. In order to elucidate an anomalous phenomena such as ionospheric disturbance, it is indispensable to observe the special distribution of electron density, which is the basic parameter of plasma physics. We propose “Rocket GPS-TEC tomography method” as a method to observe the vertical plane profiling of electron density in an ionosphere. In this research, we aim to establish the proposed method as a new measurement technique, and the following two issues. (a) Development and performance verification of GPS-TEC observation equipment, (b) Verification of tomography algorism suitable for rocket GPS-TEC tomography method.
