La roue \u00e0 filtre est un des \u00e9l\u00e9ments essentiels dans Eye-sat. C'est un m\u00e9canisme ing\u00e9nieux qui permet de faire d\u00e9filer devant l'objectif de la cam\u00e9ra haute r\u00e9solution (2048 pixels x2048 pixels) les filtres infrarouges, visibles et l'obturateur pour la calibration du capteur.<\/p>\n

Voici une belle r\u00e9alisation made in Cachan et une belle collaboration entre les d\u00e9partements de G\u00e9nie Electrique et G\u00e9nie M\u00e9canique. Une conception et r\u00e9alisation de la carte \u00e9lectronique sign\u00e9 Camille Demasson et une conception m\u00e9canique sign\u00e9e Mathieu Hautem.<\/p>\n

Un des enjeux majeurs de ce syst\u00e8me, la tol\u00e9rance contre les pannes. Lanc\u00e9 \u00e0 pr\u00e8s de 8 km\/s et \u00e0 750 km en orbite, impossible d'aller appuyer sur un quelconque bouton de reset ! L'\u00e9lectronique a \u00e9t\u00e9 prot\u00e9g\u00e9e par des d\u00e9latcheurs et mise \u00e0 l'\u00e9preuve durant les tests.<\/p>\n

Une fois ce mod\u00e8le d'ing\u00e9nierie test\u00e9 en environnement thermique et sous vide, nous lancerons la fabrication du mod\u00e8le de vol.<\/p>\n
