En début d’année scolaire, l’équipe WUSat de la Warwick University a choisi pour objectif de lancer un satellite miniature de format "CubeSat ", un cube de 10 cm de coté et de 1,33 kg, qui ouvre de nombreuses opportunités de charges utiles et de développements. Pour accélérer la conception, les systèmes de contrôle, d’alimentation et de communications sont basés sur la plate-forme Arduino. Les données expérimentales, en provenance de capteurs implantés sur des cartes séparées, sont récupérées sur carte SD.
\nUn système de ce niveau de charge utile exige des interconnexions miniatures poids plume et de très haute fiabilité. L’équipe WUSat a évalué la famille de connecteurs signal et puissance Datamate de Harwin au pas de 2 mm, ainsi que le connecteur Gecko de 1,25 mm et 2 A. Le comportement en environnement hostile des deux familles de connecteurs est satisfaisant, l’intégrité du signal étant assurée même dans les conditions extrêmes de température, chocs et vibrations rencontrées durant le lancement du satellite et tout au long de sa mission. De nombreux autres CubeSats utilisent déjà ces connecteurs pour leur taille miniature, leur légèreté et leur excellente performance.
\nDébut Avril, l’équipe WUSat a lancé avec succès son prototype de CubeSat équipé d’un ballon sonde météo. Durant son vol de 2 heures, le CubeSat a traversé la stratosphère jusqu’à 30 km au-dessus de la terre. Le ballon s’est alors détaché et un parachute s’est déployé pour ramener sans dommage le CubeSat à terre. <\/p>\n<\/p>\n
