The paper presents the results of experiments on board the Avion 6U CubeSat satellite to observe the effects of space weather, hard X-rays and gamma radiation from solar flares and cosmic gamma-ray bursts. The structure and main parameters of the Avion spacecraft, its onboard systems and payload are considered. New data on the dynamics of subrelativistic electron fluxes in the areas of precipitation from the inner and outer belts, as well as the results of observations of processes leading to a significant change in radiation conditions in the near-Earth space are analyzed. In particular, such phenomena include changes in the spatial structure of the distribution of subrelativistic electron fluxes in the outer belt due to magnetic storms and the penetration of solar cosmic rays into the polar cap regions, leading to a significant restructuring of radiation fields in the inner magnetosphere. Examples of detecting bursts of hard X-ray and gamma radiation from solar flares and cosmic gamma-ray bursts are given.
