The aerospace industry is undergoing unprecedented transformation. New players, new ventures, and new technologies drive the established business towards a transition from traditional models and strategies to automated production and innovative methods. Software architecture for space systems needs to become more agile while preserving a high standard of quality. To that end, the rigorous verification and validation process that yields high quality software products should embrace automation and take full advantage of COTS hardware and software products. In line with the industry transformation, SSL’s Flight Software Development and Validation Department uses a modular, layered architecture that has evolved over decades of orbital experience. This paper describes the SSL Flight Software Development and Validation Workflow Management System and the advantages of such a system/framework for development and verification of very complex spacecraft. This system/framework allows faster cyclical test-fix-test process and also provides a platform that can be extended for a multitude of applications.
