Electromagnetic isolation and electrical protection in spacecraft general assembly

Abstract

Spacecraft is always equipotential connected. Faults in grounding cause electromagnetic dysfunction for airborne equipment or subsystems, which can be fatal for a satellite mission. Consequences of electromagnetic problems were evaluated in his paper on system level, and typical scenarios of electromagnetic interference were analysed, based on which a recommended system grounding model was put forward. In the end, measures for electromagnetic isolation and protection in spacecraft general assembly were introduced and analysed.
