Practical Application of Model-Based Programming and State-Based Architecture to Space Missions

Innovative systems and software engineering solutions are required to meet the increasingly challenging demands of deep-space robotic missions. While recent advances in the development of integrated systems and software engineering approaches have begun to address some of these issues, these methods are still at the core highly manual and, therefore, error-prone. This paper describes a task aimed at infusing MIT's model-based executive, Titan, into JPL's Mission Data System (MDS), a unified state-based architecture, systems engineering process, and supporting software framework. Results of the task are presented, including a discussion of the benefits and challenges associated with integratingmature model-based programming techniques and technologies into a rigorously-defined domain specific architecture.
