Computer System Architecture and Software Engineering
The objectives of the SIL Community of Experts are to share knowledge and good practices, to share user experiences and feedback and to work together on topics or common issues by means of:
- the organisation of events linked to the general field of computer science
- participation in external events
- the creation of partnerships and extending the network
The over-riding objective is to respond to aerospace requirements. These requirements, as well as the issues encountered, are often very similar to those which occur outside an aerospace context. It is therefore important to open up to existing communities.
The cross-disciplinary themes dealt with are organised around the six following centres of interest:

2025 Retrospective
- Getting started with the open-source software SAGEMATH for symbolic computation
- Aiming for AI: Systems engineering in orbit!
- Agility & DevSecOps - Where do we stand?
- Software Factory Forum 2025
- KOSMOS DAY 2025
- 2nd South-West Enterprise Architecture Community Day
- CNES ONERA Workshop on Earth-space radiowave Propagation
