L\u2019ASAL f\u00eate le huiti\u00e8me anniversaire en orbite du satellite alg\u00e9rien d\u2019observation de la Terre \u00e0 moyenne r\u00e9solution Alsat-1B et par la m\u00eame occasion, ach\u00e8ve sa troisi\u00e8me ann\u00e9e au-del\u00e0 de sa dur\u00e9e de vie nominale de cinq ans.<\/p>\n

Mis en orbite le 26 septembre 2016 par le lanceur indien PSLV-C35, le satellite Alsat-1B poursuit sa mission de fourniture d\u2019images dans les modes panchromatique (r\u00e9solution 12 m) et multispectral (r\u00e9solution 24 m en mode standard ou 12 m en mode am\u00e9lior\u00e9) dans des conditions op\u00e9rationnelles nominales.<\/p>\n

Depuis son lancement, Alsat-1B continue d\u2019op\u00e9rer dans des conditions optimales gr\u00e2ce \u00e0 la robustesse et \u00e0 la performance de ses sous-syst\u00e8mes, ainsi qu’au travail rigoureux des ing\u00e9nieurs de l\u2019\u00e9quipe Alsat-1B du Centre de D\u00e9veloppement des Satellites (Oran), charg\u00e9e du suivi et du maintien du satellite en orbite. Ce travail permet de garantir la fourniture d\u2019images d\u2019excellente qualit\u00e9 au profit des utilisateurs.<\/p>\n

Depuis son lancement, le satellite Alsat-1B a fourni plus de\u00a015293\u00a0<\/em>produits images d\u2019une excellente qualit\u00e9 sur les plans g\u00e9om\u00e9trique et radiom\u00e9trique couvrant une superficie totale de plus de\u00a0344\u00a0<\/em>millions de<\/strong>\u00a0<\/em>km2<\/strong>.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n
