Guyane.<\/em> Le 27 f\u00e9vrier 2019, une fus\u00e9e Soyouz a mis en orbite six satellites de la soci\u00e9t\u00e9 OneWeb. D\u2019ici fin 2021, OneWeb compte d\u00e9ployer une constellation d\u2019environ six cent satellites dans le but de fournir une connexion Internet haut d\u00e9bit aux 3.5 milliards d\u2019individus ne disposant pas \u00e0 l\u2019heure actuelle d\u2019un acc\u00e8s \u00e0 Internet <\/span>1<\/sup><\/a><\/span><\/span>. <\/p>\n\n\n\n

Pour mener \u00e0 bien ce projet d\u2019envergure, OneWeb s\u2019est alli\u00e9 avec le groupe europ\u00e9en Airbus Defense and Space pour la conception des satellites. Pour rentrer dans ses co\u00fbts et ses d\u00e9lais, deux satellites doivent sortir chaque jour de l\u2019usine nouvellement construite en Floride, pour un co\u00fbt de fabrication de l\u2019ordre quelques centaines de milliers de dollars par satellite. Compar\u00e9s aux cinq mille satellites actuellement en orbite, construits de mani\u00e8re unique ou en petit s\u00e9rie, OneWeb et Airbus ont d\u00fb adapter le domaine spatial \u00e0 la production en s\u00e9rie.<\/p>\n\n\n\n

D\u2019autres acteurs, comme SpaceX avec son projet Starlink <\/span>2<\/sup><\/a><\/span><\/span> ou bien la Chine avec Hongyan <\/span>3<\/sup><\/a><\/span><\/span> ont aussi pr\u00e9vu de d\u00e9ployer dans les prochaines ann\u00e9es leur propre constellation comportant des centaines de satellites : ces diff\u00e9rents projets devraient r\u00e9volutionner la production de satellites ainsi que les diff\u00e9rents vecteurs pour les mettre en orbite.<\/p>\n\n\n\n

Ces constellations de satellites ne sont cependant pas la seule solution propos\u00e9e pour permettre l\u2019acc\u00e8s \u00e0 l\u2019Internet haut d\u00e9bit partout dans le monde. Google planche par exemple sur un projet de ballons stratosph\u00e9riques, Loon. Chaque ballon devrait voler \u00e0 une altitude de 20 kilom\u00e8tres et permettre une connexion haut d\u00e9bit dans un rayon de 40 kilom\u00e8tres autour de lui.<\/p>\n\n\n\n
