BS ISO 12208:2015描述了估算地球同步轨道系统中高能质子注量的方法 地球轨道（GEO）长期运行（超过11年太阳周期），并为 选择太阳质子注量模型中的置信水平，以估计太阳能电池退化。GEO观测到的许多质子数据都已存档，例如来自GMS（日本）、METEOSAT（欧空局） 然后去（美国）。这种方法是对这些通量数据（或观测数据）的直接整合 11年（定期使用）。因此，可以从太阳质子注量模型中选择置信水平。 本国际标准是一种面向工程的方法，用于特定目的，如: 估计太阳能电池板退化。购买本文件时可获得的所有当前修订均包含在购买本文件中。

BS ISO 12208:2015 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 direct integration of these fluence data (or the observed data over 11 years is used periodically).As a result, the confidence level can be selected from a model of solar proton fluences. This International Standard is an engineering-oriented method used for specific purposes such as estimating solar panel degradation.All current amendments available at time of purchase are included with the purchase of this document.
