Ionosat-Micro was a Ukrainian satellite project lead the Space Research Institute of NAS of Ukraine and SSA of Ukraine. The mission was being realized under the National purpose scientific and technical space program of Ukraine.^[2] The project was terminated in the 2020s.^[3]

History

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 could be the most ambitious satellite project in the history of studies of the ionosphere.^[4]^[5]

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).^[6] 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).^[7]

The satellite's launch was planned for 2018. As of May 2019, work on the project continued.^[8] Work on the project stopped after the 2022 Russian invasion of Ukraine and in 2026, the Space Research Institute of the National Academy of Sciences of Ukraine considered the project terminated.^[3]
