BS ISO 19923:2017规定了导致产生最坏情况的空间等离子体环境 航天器的表面电位差。它还规定了如何估计最坏情况的可能性 通过使用提供的模拟代码进行比较。本文件包括GEO、PEO和MEO中的等离子体能量和密度。这份文件没有 包括对低轨道等离子体能量和密度的描述，因为低轨道的大表面电荷是 很可能是由于航天器的仪器产生高压电。本文件仅涉及航天器的外表面充电。交叉引用:ISO 10795:2011 Ed 1ISO 20584购买时可用的所有当前修订版均包含在本文件的购买中。

BS ISO 19923:2017 specifies space plasma environments that lead to the generation of the worst-case surface potential differences for spacecraft. It also specifies how to estimate worst-case potential differences by using the simulation codes provided.This document includes plasma energy and density in GEO, PEO, and MEO. This document does not include descriptions of plasma energy and density in LEO because large surface charging in LEO is likely to be due to high-voltage power generation by instrumentation of the spacecraft.This document deals with external surface charging of spacecraft only.Cross References:ISO 10795:2011 Ed 1ISO 20584All current amendments available at time of purchase are included with the purchase of this document.
