IONOSAT project main tasks
• Scientific and methodological substantiation of the efficiency of the LEO satellites use for SW monitoring, corresponding technological realization development and tests.
• Systematic study of the dynamic response of the ionosphere to the influences “from above” (solar and geomagnetic activity) and “from below” (meteorological, seismic and technologic processes), seismo-ionospheric coupling.
• Synchronous operation with the existing sub-satellite electromagnetic and meteorological polygons.
• Calibration of modern prognostic models of quiet and disturbed ionosphere.
