BS PD ISO/TS 21979:2018通过使用再现辐射带波动的模型，定义了卫星接收的辐射通量的计算方法（轨道、运行周期）。地球辐射带的准动力学模型采用输入参数（指数值）来预测变化。输入参数从易于获得数据且与地球辐射带变化高度相关的参数中选择。交叉引用:ISO 16695:2014ISO 12208:2015ISO 22009: 2009年ISO 16698:2013购买本文件时，所有当前可用的修订版均包含在购买本文件中。

BS PD ISO/TS 21979:2018, by using a model that reproduces the fluctuations of radiation belts, defines the calculation method (orbit, operation period) of the radiation fluence received by a satellite. The quasi-dynamic model of Earth's radiation belts adopts input parameters (index values) to predict variation. The input parameters are selected from those that are easy to obtain data and have high correlation with the variation in Earth's radiation belts.Cross References:ISO 16695:2014ISO 12208:2015ISO 22009:2009ISO 16698:2013All current amendments available at time of purchase are included with the purchase of this document.
