40、under the auspices of the AIAA Electromagnetic Compatibility (EMC) Committee on Standards. It is one in a series of standards planned to codify industry best practices to ensure the very highest level of performance and reliability for the next generation of high-reliability space systems. It follow

41、s in the footsteps of MIL-STD-1541A, “Electromagnetic Compatibility Requirements for Space Systems and Equipment,” but has been thoroughly updated to reflect current industry design practices. The starting point for this document was “Electromagnetic Compatibility Requirements for Space Systems and

42、Equipment,“ TOR 2005(8583)-1, 8 August 2005, developed by Mark W. Dunbar of the Electrical and Electronic Systems Engineering Department, Electronics Engineering Subdivision at The Aerospace Corporation. However, as a result of committee deliberations, this standard draws most of its content from MI

43、L-STD-461F and MIL-STD-464A. Additional requirements deemed necessary for high-reliability space systems have been added by the committee. The intent is to address approximately 80% of space systems. For missions that do not require all the provisions of this standard, or which may need additional r

44、equirements, it is understood that tailoring may be performed to balance performance, risk, and cost to suit the needs of a particular program. The final product reflects the best EMC design and verification practices for high-reliability space systems. At the time of approval, the members of the AI
