MBSE in Real-Life Space Exploration Projects

Systems engineering techniques have been used in spacecraft design, avionics, and engineering in general for over 60 years. At the moment, space exploration industries face new significant challenges: the largest optical and radio telescopes, missions to mars and exoplanets, reusable rockets, increase of small CubeSat satellites usage, service robots, and other. The constant increase in […]

Towards Model Re-usability for the Development of Telescope Control Systems

During research and development (R&D), teams often discover similarities among system components within the same or previous projects that can be reused, with the potential of saving on cost and time. The overall development effort can be dramatically reduced by reusing the different artifacts. The ability to have a repository of reusable modelling artifacts and […]
