| Abstract: |
| According to the characteristics of new complex aerospace electronic payloads,such as diverse requirements,multiple functions,new technology applications,and continuous evolution in orbit,a set of digital system engineering methods is proposed. Through digital requirement decomposition and management,digital system design,digital collaborative design,and the integration of digital and physical verification in space and on the ground,this approach covers the entire life cycle of system requirements analysis,design and development,in-orbit operation,and evolution and upgrade,achieving digital empowerment throughout the process and effectively enhancing the efficiency and quality of system research and development. By applying this method in actual engineering projects,the system architecture design verification time is reduced from the expected three years to several months,the failure rate is lowered by 20%,and the maintenance time is shorten by 74%. |
