IONOSAT

The IONOSAT project aims to study the ionosphere and its dynamic response to various influences, including solar and geomagnetic activity, weather patterns, and seismo-ionospheric coupling. The project involves a cluster of three satellites in a polar orbit, allowing for multipoint measurements and diagnostics of disturbances. The project also includes the development of calibration models for quiet and disturbed ionospheric conditions.

  3. “Ionosat”. History SPACE EXPERIMENTS IN UKRAINE

  4. IONOSAT experiment GMES – oriented ionospheric multi-satellites mission National Space Agency of Ukraine proposal for First European Space Program

  5. 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.

  6. “Ionosat”:Main features • Orbit group is the cluster of three satellites with identical payload composition–multipoint measurements • Satellite group is at the orbit with ~ 400 kmperigee–ionospheric project • The orbit of satellite group is polar but is not solar-synchronous one–covering of all the Globeat all range of local time • Mutual distance between satellites changed in the range 50 – 3000 km–multipoint diagnostics of medium- and big-scale disturbances

  7. “Ionosat”:Orbital cluster Basic orbit for two space vehicles (SV) Io-1: liftetime = 2 years, perigee = 400 km, apogee = 780 km, inclination = 82.5 Io-2: The same, Moving off fromIо-1 increase up to 2000 km Iо-1 Iо-2

  8. “Ionosat”:Orbital cluster ThirdSV: has the same operational orbit as Iо-1 andIо-2, but with another argument of a latitude:  ~2 Iо-1 Iо-3 Iо-2

  9. “Ionosat”:Orbital cluster Group lifetime = 2 years Forhighsolaractivity period: perigee = 400 km, apogee = 780 km Orbit inclination = 82.5 Moving off ofIо-1 – Iо-2: up to 2000 km Iо-1 – Iо-3: up to 3000 km Iо-1 Iо-3 Iо-2 SV positioning accuracy – less than 20 m SV attitude accuracy – less than 10 SV attitude determination accuracy – less than 0.1
