Mission Details


The French CSO (Composante Spatiale Optique) high resolution reconnaissance satellites are the optical space component of the MUSIS program that will replace the current Helios 2 military observation satellites. CNES, the French space agency, has notified Astrium that the DGA (Direction Générale de l'Armement), the French arms procurement agency, has awarded the company a 795€ million contract for two satellites for the CSO program. The contract also includes an option for a third satellite. As prime contractor for the CSO satellites programme, Astrium will provide the agile platform and avionics, and will also be responsible for the integration work, testing and delivery of the satellites to CNES. Thales Alenia Space will provide Astrium with the very-high resolution optical instrument.
