L\u2019\u00e9quipe Airduino est un groupe amateur de passionn\u00e9s d\u2019\u00e9lectronique, d\u2019informatique et de robotique qui d\u00e9veloppe des solutions technique open source. Il avait propos\u00e9 \u00e0 Plan\u00e8te Sciences de r\u00e9aliser un vol ballon technologique visant \u00e0 tester de nouvelles techniques de communication qui pourraient \u00eatre utilis\u00e9es dans le futur \u00e0 bord des ballons \u00e9ducatifs du r\u00e9seau.<\/p>\n

Ainsi la nacelle \u00e9tait bourr\u00e9e de syst\u00e8me de communication : 5 cam\u00e9ras dont une rendue \u00ab\u00a0Live\u00a0\u00bb gr\u00e2ce \u00e0 une liaison bord sol WIFI, 1 carte Akeru-GPS nouvelle alternative \u00e0 la localisation des nacelles par GSM et un KIWI GPS. Les capteurs \u00e9taient \u00e9galement nombreux : acc\u00e9l\u00e9rom\u00e8tre, thermom\u00e8tres, barom\u00e8tre et un compteur GEIGER. Au sol, 3 stations \u00e9taient d\u00e9ploy\u00e9es pour recevoir les signaux WIFI et KIWI dont une bas\u00e9e sur une cl\u00e9 DVB-T d\u00e9tourn\u00e9e de son utilisation premi\u00e8re.<\/p>\n

Le vol s\u2019est parfaitement d\u00e9roul\u00e9 malgr\u00e9 une altitude de culmination un peu faible (22km). Le ballon a \u00e9t\u00e9 suivi durant toute sa trajectoire gr\u00e2ce au KIWI-GPS et au syst\u00e8me Ak\u00e9ru et s\u2019est pos\u00e9 sur un toit d\u2019immeuble \u00e0 Toulouse \u00e0 quelques centaines de m\u00e8tres de la Garonne. La descente sous parachute a \u00e9t\u00e9 observ\u00e9e par l\u2019\u00e9quipe de r\u00e9cup\u00e9ration \u00e9quip\u00e9e d\u2019une station de r\u00e9ception KIWI mobile.<\/p>\n

\"ballon<\/a><\/p>\n

Toutes les exp\u00e9riences ont parfaitement fonctionn\u00e9 notamment la liaison WIFI qui a permise de maintenir un lien bidirectionnel entre le ballon et le sol sur plus de 10km\u00a0! Une premi\u00e8re sans doute sur ce genre d\u2019a\u00e9rostat\u2026 La moisson de donn\u00e9es est importante car la plupart des informations issues des capteurs \u00e9taient sur \u00e9chantillonn\u00e9es et stock\u00e9s \u00e0 bord. Une s\u00e9ance de pr\u00e9sentation du projet, d\u2019\u00e9change et de retour d\u2019exp\u00e9rience devrait \u00eatre organis\u00e9e courant d\u00e9cembre \u00e0 Plan\u00e8te Sciences Midi-Pyr\u00e9n\u00e9es. Avis aux amateurs\u00a0!<\/p>\n
