The history of the project
[edit]Formation of the scientific objectives of the project "Ionosat - Micro" was for a long time, and conceptual provisions were first formulated in the 1990s, during the development of unrealized mission "Warning." Then, after tragic Spitakskii earthquake (1988), the political leadership of the USSR initiated the development of new, more effective methods of earthquake prediction, based, in particular, on the use of non-traditional for Seismology approaches such as observation of ionospheric harbingers of earthquakes etc. Thus arose the idea of mission "Warning", which, if not collapse of the USSR (1991), could be the most ambitious satellite project in the history of world studies of the ionosphere. The "Ionosat-Micro" Mission on the satellite "Mikrosat-M" embodies the ideas of the mission "Warning" on modern scientific and technological basis.[3][4]
For the diagnosis of electromagnetic processes in ionospheric plasma in the "Ionosat-Micro" Mission will be used complex instrument MWC, developed by Lviv Centre of Space Research Institute. Experimental testing elements MWC was conducted space experiments "Variant" in the Ukrainian remote sensing satellite "Sich-1M" (2004).[5] To measure the parameters of the ionosphere gas - concentration and temperature neutral and ionized gases - is a complex instrument DN - DE, established in Institute of Technical Mechanics. Flight testing sensors DN and DE experiment was carried out in "Potential" in the Ukrainian remote sensing satellite Sich-2 (2012).[6] In the "Ionosat-Micro" Mission involving foreign partners: Space Research Center of the Polish Academy of Sciences (translated) is instrument RFA creator and Space Research and Technology Institute is instrument ID-2 creator.
The satellite launch was planned for 2018. As of May 2019, work is go on.[7]
