The Satellite Observation Military Center (CMOS) has its roots in two World War I squadrons, BR 35 and BR 7, which were sent to the front to carry out reconnaissance missions, but also to adjust firing patterns.

Reunited in 1919 to form the 2nd Aviation Group, the squadron was recognized during the different conflicts it was involved in, with two commendations in the Corps Order, four commendations in the Army Order (entitling the wearer to the fourragère), and several other praiseworthy achievements. After the launch of the first Asterix satellite in 1965, France turned its attention to acquiring a military space observation capability. The first Gulf War confirmed the strategic importance of space observation capabilities, enabling autonomous situation assessment and decision-making. In 1988, the French Air Force was entrusted with the implementation of the French ground segment of the Helios military satellite program at the Creil site. The first Helios image was received in July 1995, marking the beginning of French military space observation.

CMOS was created in 2003, bringing together programming and image reception functions. In particular, it meets the image requirements of the Military Intelligence Directorate (DRM), the Joint Geographical Establishment (EGI), the National Targeting Center (CNC) and the three armed forces in metropolitan France. Finally, it supports forces deployed in overseas theaters of operation by providing satellite imagery on a daily basis. In addition, CMOS is permanently connected to its historical partners - Italy and Germany - who supply radar imagery. Today, its missions have also been extended to include electromagnetic listening.

In this way, CMOS perpetuates its reconnaissance traditions by providing space-based support for military operations, thus contributing to France's autonomy of assessment and decision-making.

An exhibition at the center now retraces these two anniversaries. The exhibition was inaugurated by Air Force Major General Philippe Adam, Commander of the French Space Command (COMESPACE), at the November 16 ceremony.
