Building a Collaborative MBSE Model for Spacecraft Design Based on an Enterprise Architecture Approach

In recent years, the complexity of spacecraft systems has been increasing, and the traditional document-based design model is increasingly changing to a model-based design model, which often encounters problems such as inefficient collaboration and insufficient support from information systems in the application process. In this paper, we propose to adopt an enterprise architecture approach and analyze the business architecture, data architecture and application architecture of the MBSE-based solution design process in spacecraft based on the TOGAF enterprise modelling method, and then build a standardized and efficient MBSE collaborative design model for spacecraft, and carry out a typical application to provide a deeper application of the MBSE collaborative design model for spacecraft. The paper provides guidance for the further application of the MBSE collaborative design model and the construction of MBSE-related information systems.
