Web13 apr. 2024 · 60 Saturn ionospheric electron density profiles have been generated and verified. There appears to be an underlying morphology of a broad layer at relatively high altitude and a series of narrower layers at lower altitude. The vertical structure of Saturn's ionosphere depends on latitude and local time. Web12 apr. 2024 · As an ionospheric density, a variable depending on the ray path and transmission time, is related to the solar activity and magnetic strength, it is reasonable to set the following factors as inputs of the NN model: (1) Ray location. The position of GNSS receivers and the azimuth and altitude of satellites are necessary to fix a ray path.
