Design and supply of equipment for space applications

Nowadays, satellites are powerful, strategic tools for Earth observation. Indeed, thanks to the considerable quantity of information they gather, they are key to understand and analyze how our planet works. 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 have a direct impact on the population’s activities and safety.

Having an old-established history in the research and development of complex systems for space applications, we make a valuable technological contribution to the programs of the major players of the European space 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, adaptability and high-tech skills of Bertin and Winlight teams (optical, high precision mechanics, space electronics, control center, thermal engineering, physical modeling, system engineering, etc.), we offer a wide range of services to our customers and assist them in designing and supplying high-technology equipment dedicated to the space industry (ground test equipment, embedded optical and electronic equipment, image processing, heavy load transport).

Strengthening our space market’s offer with Winlight

In 2017, Winlight System, a company specialized in the design and manufacture of high-performance optical systems and components dedicated to the space industry, joined Bertin Technologies.

Winlight has an international reputation and technical expertise in the research and supply of systems in the space sector, defense, astronomy and big science instruments. This acquisition strengthens the group's offer by building high-performance optical components and mechanical systems.

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 to conduct Assembly, Integration, Testing and Validation (AITV) phases. They are used to test, qualify, and validate instruments such as very high-resolution imagers, radar sonars or advanced telescopes.

These optical test systems (OGSE) are strategic for manufacturers since they enable the validation of the optimum performances of the instruments that are to be integrated into the satellite. These test benches must therefore be of extreme precision to guarantee the most satisfactory optical performances along with the best mechanical stability and remote control, even in an ultrahigh vacuum environment.

Mechanical ground equipment (MGSE) allow for the integration of critical components (such as mirrors) with very high precision and stability. We also develop some MGSEs to reproduce zero gravity conditions during ground test campaigns to make those tests as realistic as possible

Design of embedded systems on satellite platforms

We design and manufacture systems or subsystems that are sent into space. These instruments or pieces 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. As earth observation, scientific and defense missions depend on the spacecraft’s proper functioning, Bertin and Winlight teams use state-of-the-art technologies to achieve the expected performances. Our teams make a point in fulfilling the very high stability, reliability, cleanliness and quality assurance requirements of that equipment.


Unique skills

These test benches and complex systems are on the cutting edge of technology and offer state-of-the-art innovative solutions. The expertise of Bertin and Winlight teams is especially based on the mastery of special 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

State-of-the-art infrastructure

The high level of reliability of our services for the space sector is also due to our state-of-the-art infrastructure.

Three clean rooms dedicated to the assembly, integration, testing and validation of instruments:

  • Control of particle pollution: ISO 5: 44m² + 140 m², ISO 8: 45m²
    • Molecular pollution control (VOC absorption)
