Аннотация:Multi-channel astronomy is one of the most important and rapidly developing field of modern physics. The well known result of multi-channel observations is simultaneous detection of gravitational wave and gamma ray bursts associated with neutron star mergerevent. This observation open a new window to study the Universe, and actually triggered the broad scale study of astrophysical phenomena in hard X-Rays and gammarays by orbital experiments together with ground based observations of gravitationalwaves, neutrino and ultra-high energy cosmic rays. From this perspective it appears that small satellites of CubeSat type are quite appropriate for multi-channel observations of astrophysical transients because it is the cheapest way to realize all-sky monitoring observations by orbital instruments. Presently at D.V. Skobeltsyn Institute of NuclearPhysics of the M.V. Lomonosov Moscow State University (SINP MSU) a new project named Universat–SOCRAT is under development which is intended for operational monitoring of near-Earth’s radiation environment and monitoring of electromagnetic transients in the optical, UV, X-ray and gamma ranges. Here we discuss the first results of charged particles, gamma quanta fluxes and UV-emission measurements from the upperatmosphere in several CubeSat missions, which were successfully launched in 2019, 2020.
