Description
A few years ago, ESA has launched OPS-SAT mission, the first CubeSat mission designed and operated by ESA with the goal to provide a low-cost, open, and flexible flying ‘laboratory’ – a powerful platform for in- orbit demonstration of new, innovative control systems and software. The OPS-SAT team was large and diverse and has faced some challenges and pain points during the design process. ESA has launched a study to investigate on the possible support of an MBSE approach to alleviate some of the pain points and to prepare a reference model for future IOD missions.
In this presentation, Samares Engineering explains how it was possible to address most of the pain points with the selected MBSE framework and gives some examples including the ability to ensure end to end traceability from mission down to the technical components. The presentation also explains the initial process used to perform reverse engineering from OPS-SAT document pack, the limits to identify the system functions and the suggested improvements to ease this process.
Finally, the presentation focuses on OPS-SAT 2 mission, and demonstrates that the operational concept can be formalized as a model with behavior, able to support simulation. This simulation can be used as an efficient toolbox to run different operational scenarios including the upload, installation and run of a new experiment, and check that the model behaves as expected, or highlight issues not envisioned so far.
