About us

We rely on more than 50 years of experience in optronics and neutron technology to develop innovative and competitive solutions for our commercial and institutional customers.

As a subsidiary of the European leader in access to space, ArianeGroup, we are operationally independent.
We are also a historical and strategic defence supplier, a characteristic that guarantees us a solid base of industrial activities, thereby affirming durability and reliability.
Our institutional clients' high level of requirements has led us to develop an extraordinary expertise that now benefits stakeholders in space, mining, industry and research. We preserve and enhance this exceptional technological know-how by participating in scientific programs that push the limits of the state of the art: the caesium atom clock Pharao, the seismometer of the Mars mission InSight, cells of Pockels for the Megajoule laser, etc.

Sodern's core business is the series production of star trackers that enable satellites to orient themselves precisely in space, and neutron systems for analysing and detecting materials.
To meet the expectations of changing markets, we set high competitive requirements for ourselves: the implementation of lean management, perfect understanding of our customers' needs, agility and optimisation of production costs are the commitments that allow us to maintain a competitive edge with a very high level of customer satisfaction, and to consolidate our position as a world leader in several markets.

Our commitments


The technical challenges and the high level of demand inherent in the markets we are present on, including space, defence and science, have led us to develop exceptional expertise and place a high value on quality and the reliability of our products.

This culture of performance is found on all our programmes. For example, during seven million hours of cumulative operation, the software of our traditional star trackers did not record any errors and did not fail.


To achieve this goal, we reorganised our entire production chain, generalising the principles of lean management, and investing in optimised means of production. Our products are designed to sacrifice nothing for quality, while resolutely seeking simplicity, efficiency and economy.

By making this competitiveness objective an intrinsic part of our culture, our products and our structure, we have managed to impose ourselves as a New Space actor with our Auriga star tracker, to reinforce our market share on the traditional star tracker segment, and to continue to grow with exports in the neutron markets

Our know-how

Neutron technology

Neutronics is a branch of neutron physics, involving a sub-particle of the atom.
Thanks to our experience in deterrence, we now master the most advanced applications and we are, on the industrial front, one of the world leaders in neutron transport.

Most of our activity is now civil. The wealth of our know-how and our equipment allows us to develop solutions adapted to a wide variety of needs.


Thanks to various fields of knowledge derived from our neutron activities, such as vacuum control, we quickly diversified into the field of optronics.

Thus, we design, develop and produce systems using both optics and electronics.
We work for a wide variety of sectors, but space and science are two of our preferred markets.
