About Comat

Comat has manufactured flight instruments and equipment for the space industry for nearly four decades, operating from Toulouse in the heart of France's aerospace ecosystem. As a subsidiary of the Hemeria group, Comat combines precision mechanical engineering with deep space-sector experience.

The company organizes its work across three business lines. In Small Sat, Comat supplies reaction wheels, solar array drive mechanisms (SADM), deployable antennas, and its NANOBOOM deployable boom system. In Telecommunication & Observation, Comat builds rotary actuators, gear pumps, liquid pumps, and flight hardware for instruments such as the IASI-NG atmospheric sounder. In Exploration & Science, Comat has contributed hardware to missions including the SuperCam instrument on NASA's Mars Perseverance rover, the DECLIC fluid physics experiment, Euro Material Ageing facility, and dust removal systems for lunar/planetary surface operations.

Comat's customer and partner network includes CNES, ESA, CNRS, Airbus Defence and Space, DGA, and Anywaves, reflecting its role as a trusted equipment supplier across French and European space programs.
