Fausto Cortecchia,Marco Riva,Lorenzo Busoni,Carmelo Arcidiacono,Mauro Patti,Laura Schreiber,Matteo Lombini,Eric Stadler,Emiliano Diolaiti,Paolo Ciliegi,Philippe Feautrier,Simone Esposito,Roberto Ragazzoni +12 more
TL;DR: An overview of the systems engineering processes and tools implemented to MAORY project during preliminary design phase is provided and the role of MAORY technical budgets to derive requirements on subsystems is illustrated.
Proceedings ArticleDOI
Product assurance for the PLATO Telescope optical unit
Simonetta Chinellato,Giovanni Postiglione,T. Bandy,Enrico Battistelli,Maria Bergomi,Federico Biondi,Francesco Borsa,Flavia Calderone,Virginie Cessa,Jacopo Farinato,Davide Greggio,Demetrio Magrin,Luca Marafatto,Francesca Molendini,Matteo Munari,Silvia Natalucci,Andrea Novi,Isabella Pagano,Daniele Piazza,Roberto Ragazzoni,Mario Salatti,Valentina Viotto +21 more
TL;DR: The main tasks of the Product Assurance process for the Telescope Optical Unit (TOU) of the ESA PLATO mission is described, that starts from the design phase and proceeds through all phases, up to the final product, with the aim of improving the likelihood of success of the mission.
