Abstract:

This paper describes an architecture for simplifying the spacecraft design and maintenance process: Object Oriented Spacecraft Architecture. Like object oriented programming, the strategy allows for the modularization of components so that they are inherently reusable and easy to maintain. This approach treats the design problem as an open-ended systems problem, expecting change to occur in systems design and allowing for easy change and evolution. The object oriented architecture offers a clean and rational approach to standardizing spacecraft subsystems and interactions among subsystems. This architecture is based upon a common spacecraft communication bus on which all subsystems communicate messages and data. A common bus forces subsystems to become modular and reusable.
