Our World

With a legacy of 30 years’ expertise in Defense and Space, HEMERIA was founded in July 2019 after the historical shareholders decided to transfer NEXEYA to a foreign group and to refocus the strategy on sovereign activities.

From the ocean depths to the infinity of space, we assist our customers with the deployment of their tactical missions in complex environments in response to strategic challenges, and help them contribute to a safer, fairer and more sustainable world.

In Defense, we design and manufacture embedded electronic equipment for the Strategic Deterrent Force and electro-optical tracking systems for flight test centers. We also provide through-life support for strategic assets to guarantee optimal operational readiness.

In Space, HEMERIA is above all a long-standing benchmark player in Europe, supplying composite panels, electrical harnesses and thermal protections for most LEO and GEO satellites of major prime contractors. Through this experience, HEMERIA has also become the federator of the French smallsats industry. In cooperation with the French space agency CNES, we produced ANGELS, the first French industrial smallsat successfully thrust into orbit in 2019, a project that launched the industrial smallsat adventure in France. Today, many other projects are under way, including the 25-smallsat IoT constellation for KINEIS.

In 2022, HEMERIA strengthens its activity with the acquisition of CNIM Air Space which becomes HEMERIA AIRSHIP, leader European stratospheric, tethered and maneuvering aerostats.

Leveraging our unique and all-round expertise, we supply dependable, innovative and competitive products to our institutional and commercial customers in France and the rest of the world.
