GB/Z 44002-2024 Space environment—Method of the solar energetic protons fluences and peak fluxes determination

Scope

This document presents the differential energy spectra of solar energetic proton fluxes and peak fluxes for spacecraft operating in Earth's magnetosphere under different solar activity conditions, with an energy range of 0.1 MeV to 103 MeV. If we consider the variation with the distance to the Sun's center, this method is suitable for determining the solar energetic proton fluxes and peak fluxes throughout the entire heliosphere. When taking into account the geomagnetic shielding effect, this method is applicable to calculating the solar energetic proton fluxes and peak fluxes for spacecraft in near-Earth orbit and human space station orbits. This document is suitable for calculating the probability of the occurrence of solar energetic protons, which have significant impacts on materials, electronic components, and living organisms.
