Integrated information modeling of engineering digital prototyping for satellite design

The design and development of aerospace product is a collaborative multi-discipline project. The integrated and consistent information modeling of all the information, models, documents and other product data generated during design and development is critical to success. An integrated information model, defined as EDPS (Engineering Digital Prototyping for Satellite) is proposed. Aiming at modeling product information in system design, multi-discipline analysis and simulation, process planning, and prototype testing, be compatible with different data and file format, providing a consistent product semantics information model, EDPS is defined and represented based on ontology to promote collaboration in product development. The composition and representation method of EDPS is proposed. The satellite design process driven by EDPS is discussed as a case study.
