Phased Demonstrations of MBSE in Small Demonstration Satellite Series: Development of System Model and Environment for Full Application of MBSE

Abstract

AbstractThe Japan Aerospace Exploration Agency (JAXA) has been implementing phased and progressive demonstrations of the Model‐Based Systems Engineering (MBSE) applications, using small demonstration satellite series, so called the Rapid Innovative Payload Demonstration Satellite (RAISE), as a demonstration pre‐cursor. The purpose of the activity is to establish a practical methodology of the MBSE application to satellite projects, to promote its practices, and to infuse MBSE to the Japanese space community. These RAISE satellites are 100kg‐class flagships in the Innovative Satellite Technology Demonstration Program, which provides on‐orbit demonstration opportunities for new technologies and key‐components. This paper presents the phased demonstration strategy, an overall approach, and the technology development of a system model being built for the full application of MBSE to RAISE‐4. For the technology development, the paper covers framework, modeling scope, system model building, system model collaboration with analysis/simulation tool, introduction of design rationale and concerns, information sharing through OpenMBEE, for our full application of MBSE.
