Optoi has developed hermetic optocouplers, in previous activities funded by ESA. On a first project, the devices have been subjected to a full ESCC campaign following ESCC 2265000. This activity allowed the determination of the device’s functional boundaries and included a radiation campaign.

Under ESA contract number 20945/07/NL/IA, Alter Technology developed test benches for the characterization and qualification testing of 16bit (0.01º accuracy) Contactless angular sensors prototypes for telecom satellites’ extended life mechanisms. Angular sensors (AS) are position devices that provide the displacement in angular degrees concerning a fixed point or an arbitrary reference. The central performances to be measured are accuracy, hysteresis, and measuring range. These parameters must be measured before, during, and after applying environmental treatment during the qualification test campaign.

160 ILLUMINATED PHOTODIODES Development of a complex setup capable of simultaneously measuring 20 solar sensors under homogeneous incident light During the last decades, continuous technology improvement has allowed the development of increasingly smaller and cheaper satellites. Different private companies figured out this fact and started to think about the possibilities of having their satellite constellation.

The Strain Gages are used to measure the deformation of materials. These devices are widely used when the deformation of a structure is relevant such as the wings of a plane or the structure of telescopes or rockets. The necessity of testing these strain gages at a wide temperature range leads to the necessity of coupling force-deformation equipment to climatic chambers.

The SuperCam is a next-generation scientific instrument that examines rocks and soils with a camera, laser, and spectrometers to seek organic compounds that could be related to past life on Mars. It can identify the chemical and mineral makeup of targets as small as a pencil point from a distance of more than 20 feet (7 meters).

Thermal Vacuum Testing is necessary to be carried out because the environmental conditions in the space are extreme, the combination of low pressure and extreme temperatures can cause the failure of a component. That is why in Alter Technology, we test the components in similar conditions.

Space agencies have carried out numerous research projects to develop systems to detect and quantify the concentration of Greenhouse gases, such as carbon dioxide and methane, which are the main drivers of climate change. The measurement system used for this purpose is called LIDAR (Light Detection and Ranging).
