Description
The main objective of the project “Application of MBSE to reverse‐engineer OPS‐SAT and improve OPS‐SAT2” is creating a model of the existing OPS-SAT system design through a reverse-engineering process.The model aims to be built in a way that it is most useful for OPS-SAT engineers to understand and discuss the existing design and use this as a basis for further development of the OPS-SAT system. Through a survey and series of workshops and interviews withthe OPS-SAT Engineering team the mission challenges and “pain point” are gathered with a special intension to use OPS-SAT as a first of its kind for ESA aiming at testing and validating the benefit of new techniques, i.e. MBSE. Based on the findings an MBSEmodelling framework and software environment is selected to support the activity based on the overall modelling objectives and sought output. This modelling framework (i.e. SysML language, Enterprise Architect Tool Suite, SPES Modelling Method) has been usedto implement the OPS-SAT model, from which a generic model template and respective documentation has been derive to support other IOD missions, potentially OPS-SAT2. To close the loop, the identified pain points have been mapped to concrete solutions implementedin the project to assess the expected benefit for future activities. In this project OHB System AG was acting as prime contractor together with the consortium partners LuxSpace SARL, GPP Communication GmbH & CO KG as well as Technische Universität Graz providingconsultancy for the OPS-SAT design.
