Automating the processing of data – which has become too large to be sent to the ground – directly on board satellites and developing digital twins of the Earth that are more complex than those currently in place. These are the topics on which the National Center for Space Studies (CNES) and the National Institute for Research in Digital Science and Technology (Inria) have decided to combine their expertise.
Ultra-compact AI and enriched digital twin
For on-board processing, Inria will have to work in particular on ultra-compact artificial intelligence capable of analyzing small images, in order to reduce the weight of the data and optimize storage. We can’t just add memory sticks, because 100 grams more on a satellite means thousands of euros to pay.“, observes Alain Girault, the deputy scientific director of Inria.
On digital models of the planet, the challenge is to enrich them, for example by incorporating thermal information into 3D representations of buildings. In order to open up the use of these models to regional planning, defense or even the study of the effects of climate change. Cnes and Inria expect the first concrete results within five years. #
