International Requirements for Payload Multi-Platform Reuse Methodology

In this paper, we discuss the need for international requirements to assure the EMC of Payload (Instruments/Experiments) use on multi-agency, multinational collaborations and multi-platform re-use. We examine possible environment exposures through mission life-cycle stages and the impact to EMC requirements and environment limits based on the processing path. We comment on existing Agency/National space standards, the level of harmonization between them, and possible integration to provide a common International Space Standard that would provide reasonable product assurance for EMC. We look at ISO 14302, and suggest revision/creation of a top-tier management document that facilitates the necessary EMI control methodology for multi-Agency, multi-national and multi-platform programs; integrated use of the individual agency/national space standards and international consensus on mandatory minimum environment levels.
