Satellites are powerful tools for observing the Earth and, through the enormous quantity of information they generate, they are a great vehicle to understand and analyze how it works. The control of multiple parameters observed from space, such as CO2 concentration, ice thickness, ocean temperatures, or wind speed, can be used to quantify and understand climatic or meteorological phenomena that directly impact population activities or safety.
With a long history of research and development of complex systems for space, we make a valuable technological contribution to the development programs of the major European masterpieces of that industry.
The systems embedded in the satellites cannot suffer any technological failure in order to successfully carry out their mission when in orbit. This is why the testing, control and calibration phase on the ground is decisive in order to put them in real operational conditions.
Thanks to the agility, reactivity and high-tech skills of our teams (optical, high precision mechanics, space electronics, control center, thermal engineering, physical modeling, system engineering, etc.), we offer a wide range of services to its customers to assist them in designing and supplying high-tech equipment dedicated to the space industry (ground test equipment, embedded optical and electronic equipment, image processing, heavy load transport).
Expertise in the design and development of optical and mechanical test benches
We develop ground test equipment (OGSE/MGSE) for satellite applications. These optical and mechanical test benches are fully designed and developed up to the Assembly, Integration, Testing and Validation (AITV) phases. They are used to qualify, test and validate instruments such as very high resolution imagers, radar sonars or advanced telescopes.
These optical test systems (OGSE) are strategic for contractors since they allow for the validation of the performances of the instruments that are then loaded onto the satellite. These test benches must therefore be of extreme precision in terms of optical performance, mechanical stability and remote control, often in an ultrahigh vacuum environment.
Mechanical ground equipment (MGSE) allow the integration of critical components (such as mirrors) with very high stability and precision. We also develop some MGSEs in order to reproduce zero gravity conditions during ground test campaigns to make these tests as realistic as possible.
Design of embedded systems on satellite platforms
We design systems or subsystems that are sent in space. These instruments, or part of optical, opto-mechanical and electronic instruments are fully developed up to the assembly, integration, testing and validation phases on behalf of major space contractors. Earth observation or defense mission via satellite depends on their proper functioning. They use state-of-the-art technology pushed to the limits in order to achieve the expected performance. Our teams are in control of the very high stability, reliability, cleanliness and quality assurance requirements.
These test benches and complex systems are on the cutting edge of technology and offer state-of-the-art innovative solutions. The expertise of our teams is based in particular on the mastery of specialized skills in the following areas:
- High stability opto-mechanical aiming instrumentation
- Spectro-radiometric, optical and mechanical calibration instruments
- High precision mechanical instrumentation
- Instrumentation for optical quality tests
- Spectroscopy instrumentation
- Electronic and opto-electronic instruments
- Optical filtering instruments with high spectral discharge
- Control, operation and supervision of systems
- Fiber optic technology for specific environments
The high level of reliability of our services for the space sector is also due to our state-of-the-art infrastructure.
