On 22-24 November 2022, RHEA Group experts in system engineering and concurrent design took part in the European Space Agency’s (ESA) annual Model Based Space Systems and Software Engineering workshop. RHEA’s COMET software, used for concurrent design by ESA, also featured at the event.

ESA’s annual Model Based Space Systems and Software Engineering workshop took place this year at the Airbus Leadership Academy in Toulouse, France, after being staged as a virtual event in 2021 due to the COVID-19 pandemic. The event plays an important role in sharing knowledge of model-based system engineering (MBSE) activities in the space sector in Europe, with attendees from across space agencies, industry and academia. This year’s workshop was organized in collaboration with Airbus and the French space agency CNES.

Across the two days, keynote speakers outlined the need for MBSE to be used in a sustainable and responsible way, and for user-centric approaches to MBSE. ESA provided a detailed report on MBSE activities at the Agency, in which RHEA’s COMET plays a pivotal role in the early phases of space system design. The direction of the ESA’s MB4SE and Overall Semantic Modelling for System Engineering (OSMoSE) working groups were also presented.

Industry speakers covered both their visions for future MBSE strategies and their current experiences, including their pain points. Topics ranged from model reusability and variability between projects to digital continuity.

Speakers from RHEA presented papers on:

  • The Model-Based System Engineering Hub (MBSE Hub) – Alex Vorobiev, Projects Delivery Manager MBSE and Concurrent Design Belgium
  • Enhancing the MBSE Hub for AIV Reporting Needs – Nieves Salor Moral, Project Manager and Senior Software Engineer
  • ECSS-E-TM-10-25 Evolution and the State of COMET – Sam Gerené, Competence Area Lead Concurrent Design & MBSE


At RHEA, we have been working with fully functional MBSE environments for the early phases of complex projects for many years using concurrent design. The event provided a great opportunity for our team to exchange ideas with other MBSE experts and to present the engineering solutions developed by RHEA, in particular COMET – our open source collaboration tool for the early phases of complex engineering projects. COMET has also been used by ESA as the mission parameter database for the Plato space mission.
