Sirius Space Services Tech Stack

Small-lift launcher manufacturer developing reusable vehicles for European satellite operators

Aviation and Aerospace Component Manufacturing Nanterre, Île-de-France 51–200 employees Founded 2020 Partnership

Sirius Space Services designs and manufactures small-lift launchers (payload capacity up to 1,100 kg) from its integrated production facility near Paris. The tech stack—MATLAB, Simulink, ANSYS, ABAQUS, NASTRAN for multi-physics simulation paired with CAD tools (SolidWorks, CATIA, NX) and manufacturing software (Mastercam, CNC)—reflects a vertically integrated aerospace operation focused on propulsion optimization and structural analysis. Active projects cluster around engine functional optimization, GNC (guidance, navigation, and control) robustness, and launcher subsystem integration; pain points center on production scaling, reusable-engine durability, and meeting aerospace qualification standards—typical constraints for a young launcher company ramping manufacturing.
