Designing the Dragon COTS (Commercial Orbital Transfer System) for EMI/EMC interface compliance to the International Space Station (ISS) is a complex task. It involves designing Dragon for self-compatibility, compatibility with the Falcon 9 Launch Vehicle, designing to the LEO Space radiation environment, and designing for interface compatibility to the ISS mechanical, electrical and RF interfaces. This paper, Part II, describes the Space Exploration Technologies analysis and test verification methods used to achieve Dragon spacecraft self-compatibility, compatibility with the Eastern Launch Range RF requirements, and interface compatibility to the ISS requirements for EMC emissions and susceptibility.
