BS ISO 19923:2017

This standard BS ISO 19923:2017 Space environment (natural and artificial). Plasma environments for generation of worst case electrical potential differences for spacecraft is classified in these ICS categories:

• 49.140 Space systems and operations

This document 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.
