Abstract
The paper presents on-board measurements of space radiation characteristics during solar proton events in 2017-2018. The measurements are carried out by the spectrometers on-board Russian spacecrafts in geostationary and polar orbits. The open access GOES data are also used. The solar proton fluxes in geostationary and polar orbits during solar proton events were determined using processed measurements. The single event upset rates were calculated for different events in different orbits using obtained and simulated solar proton spectra. The single event upset rates and solar proton events magnitudes were compared for 2017-2018 and other years of the 24th cycle. The comparison analysis results are addressed in the paper.
