Abstract:
The National Institute for Space Research (INPE) has always developed satellite control systems with architectures that may be used as much as possible by future satellites. The present challenge is to build an Adaptive Satellite Control System, using the technology of the Dynamic Object Model, so as to comply with later requirements without having to make significant changes in the code. According to this technology, object structures and their behavior are mapped onto a database, so end-users can modify them by using configuration tools and, possibly, a domain specific language. This paper proposes a Dynamic Object System, using an architecture that facilitates its long term use by the satellite control systems. The paper also presents a new approach for representing Dynamic Objects, based on a tree of entities and properties.
