             abstract = "Satellite systems are becoming even more complex, making technical 
                         issues a significant cost driver. The increasing complexity of 
                         these systems makes requirements engineering activities both more 
                         important and more difficult. Additionally, todays competitive 
                         pressures and other market forces drive manufacturing companies to 
                         improve the efficiency with which they design and manufacture 
                         space products and systems. This imposes a heavy burden on 
                         systems-of-systems engineering skills and particularly on 
                         requirements engineering which is an important phase in a systems 
                         life cycle. When this is poorly performed, various problems may 
                         occur, such as failures, cost overruns and delays. One solution is 
                         to underpin the preliminary conceptual satellite design with 
                         computer-based information reuse and integration to deal with the 
                         interdisciplinary nature of this problem domain. This can be 
                         attained by taking a model-driven engineering approach (MDE), in 
                         which models are the main artifacts during system development. MDE 
                         is an emergent approach that tries to address system complexity by 
                         the intense use of models. This work outlines the use of SysML 
                         (Systems Modeling Language) and a novel knowledge-based software 
                         tool, named SatBudgets, to deal with these and other challenges 
                         confronted during the conceptual phase of a university satellite 
                         system, called ITASAT, currently being developed by INPE and some 
                         Brazilian universities.",
