摘要

Over the last few years, the European Space Agency (ESA), together with the European industry, has been steadily evolving an ESA community licensed novel Model-Based Systems Engineering (MBSE) application, the Ground Segment Engineering Framework (GSEF). This paper outlines an ongoing GSEF rollout initiative, in particular its application to the end-to-end ground segment system engineering of ESA Science Programme missions. This initiative involves the utilization of the framework for full life cycle activities, including requirements management, system architecture definition, co-engineering of system interfaces and verification, and test management. Such onboarding, realized through close interaction and agile iteration between MBSE experts, developers, and mission representatives, has been performed utilizing as reference the PLAnetary Transits and Oscillations of stars (PLATO) mission, a medium-class mission in ESA's Cosmic Vision programme. A future-proofed and re-usable approach is proposed, leveraging the modern features of GSEF, including a Systems Modelling Language v2 (SysMLv2) based metamodel, configurable user interfaces, extension and application of the Unified Architecture Framework, reference libraries, data import and export features, artefact generation, user-defined queries and fully web-based editing capabilities. Through re-usability mechanisms, an enduring approach is expected to achieve significant efficiency gains and return on investment as the number of onboarded missions increases.
