Web31 dec. 1993 · Recently, several tomographic techniques for ionospheric electron density imaging have been proposed. These techniques reconstruct a vertical slice image of electron density using total electron content data. The data are measured between a low orbit beacon satellite and fixed receivers located along the projected orbital path of the … WebAbstractThe insufficient number of low-elevation observations is a limitation of the three-dimensional ionospheric computer tomography (CT) based on the global navigation satellite system (GNSS). To solve this problem, accurate prior information on the ...

Web10 apr. 2024 · The computerized ionospheric tomography technique is extensively being applied to imaging ionospheric electron density (IED) distributions based on Global Navigation Satellite System (GNSS) observations. The voxel-based model is usually utilized in ionospheric tomography, with the ionosphere being divided into many cubic voxels. Web15 mrt. 2024 · CSES-01 is a sun-synchronous satellite probing the ionosphere around two fixed local times (LTs), 14 LT in the daytime sector and 02 LT in the night-time sector, at an altitude of about 500 km. Previous studies evidenced that CSES-01 seems to underestimate N e measurements with respect to those acquired by similar satellites or obtained from … port of entry deutsch
