Space systems. Space environment (natural and artificial). Observed proton fluences over long duration at GEO and guidelines for selection of confidence level in statistical model of solar proton fluences1 Scope This International Standard describes a method to estimate energetic proton fluences in geosynchronous earth orbit (GEO) over a long duration (beyond the 11 year solar cycle), and presents guidelines for the selection of a confidence level in a model of solar proton fluences to estimate solar cell degradation. Many of the proton data observed in GEO are archived, for example from GMS (Japan), METEOSAT (ESA) and GOES (USA). This method is a
