Lighter than air platforms

CNIM offers a comprehensive range of aerostats through its subsidiary, CNIM Air Space. These balloons are made from flexible envelops which are then filled with lighter-than-air gas.

The strengths of CNIM Air Space’s products include persistence, versatility, safety and low operating costs.

Our solutions

Satellite equipment

CNIM and its subsidiaries, Bertin & CNIM Air Space, possess highly specialized systems and skills that meet the requirements of the space sector.

CNIM Group provides complex systems for harsh environments such as ground-based and on-board critical equipment, high-precision test benches, remotely operated systems etc.

CNIM has a 220m2 Iso6/7 clean room on its site at La Seyne sur Mer, which meets the most demanding standards in use within the industry.

Our solutions

Ground equipment

Bertin fully designs & develops Optical Ground Support Equipment (OGSE) for space applications, throughout the Assembly, Integration, Testing and Validation (AITV) stages. These systems allow for the performances’ validation of the onboard instruments before the integration into the satellite, with an extreme accuracy in terms of optical performance, mechanical stability and remote control, often in an ultrahigh vacuum environment
