Towards Bidirectional Engineering of Satellite Control Procedures Using Triple Graph Grammars

The development and maintenance of satellite control software are very complex, mission-critical and cost-intensive tasks that require expertise from different domains. In order to adequately address these challenges, we propose to use visual views of the software to provide concise abstractions of the system from different perspectives. This paper introduces a visual language for process flow models of satellite control procedures that we developed in cooperation with the industrial partner SES for the satellite control language SPELL. Furthermore, we present a general and formal bidirectional engineering approach for automatically translating satellite control procedures into corresponding process flow visualisations. The bidirectional engineering framework is supported by a visual editor based on Eclipse GMF, the transformation tool HenshinTGG, and additional extensions to meet requirements set up by the specific application area of satellite control languages.
