This standard provides requirements relative to various plasma interactions that can result when a high-voltage system is operated in the Earth's ionosphere and standard practices to eliminate or mitigate such reactions. The purpose of this standard is to provide a design standard for high-voltage space power systems (> 55 volts) (V))that operate in the plasma environment associated with LEO (altitude from 200 and 1000 km and latitude between -50 and +50 degrees). Such power systems, particularly solar arrays, are the proximate cause of spacecraft charging in LEO; and these systems can interact with this environment in a number of ways that are potentially destructive to themselves as well as to the platform or vehicle that has deployed them.
