(report 2016)

The main goal of the project is to evaluate the level of maturity of GPU technology for space missions. The assessment focuses on the core components of the mission design and on the use of an accelerator for data processing and interpretation.

The R&D component of the project, mainly funded through ESEP, focuses on the qualification of the component for the space environment, particularly in the context of nano-satellite technology. This is to validate the proper operation of a GPU when shipped under conditions similar to those undergone in orbit. Thermal cycling and radiation exposure tests are conducted as well as test on electrical consumption and heat dissipation. At the same time, target missions must be identified and a corresponding test plan developed in collaboration with the scientific or technical teams responsible for the other subsystems. Thanks to the support through ESEP, the first qualifying tests were carried out, including the validation of the thermal cycling component and the first irradiation tests. The implementation of a first step of a data processing "pipeline" was done using the example of sharpening images taken from the orbit. A study of the characteristics of this pipeline, in terms of computing performance and energy consumption, is underway.
