SHERBROOKE, Qu\u00e9bec, Canada, [22 octobre 2026] – Le 22 octobre 2026 marque le 25e<\/sup> anniversaire de la mise en orbite du satellite PROBA-1.<\/p>\n

Le projet \u00ab PRoject for On-Board Autonomy-1 \u00bb, de son nom complet, \u00e9tait une mission d\u2019observation de la Terre et de d\u00e9monstration de technologie de l’Agence spatiale europ\u00e9enne (ASE), principalement la d\u00e9monstration que l\u2019autonomie \u00e0 bord d\u2019un satellite peut r\u00e9duire les co\u00fbts d\u2019exploitation d\u2019une mission et assurer une meilleure fiabilit\u00e9 et performance du satellite. Verhaert Design and Development de la Belgique (devenu ensuite QinetiQ Space et finalement Redwire Space) \u00e9tait le maitre-d\u2019\u0153uvre du satellite. Ce fut la premi\u00e8re mission spatiale \u00e0 laquelle contribuait NGC.<\/p>\n

Le logiciel autonome du syst\u00e8me de commande d’attitude et d’orbite (SCAO) du satellite d\u00e9velopp\u00e9 pour cette mission a \u00e9t\u00e9 \u00e0 l\u2019origine du succ\u00e8s de NGC dans l\u2019adaptation du logiciel SCAO pour les sept autres satellites de l\u2019ASE qui ont \u00e9t\u00e9 lanc\u00e9s depuis PROBA-1.<\/p>\n

Pr\u00e9vu pour une mission de deux ans, PROBA-1 a fourni des donn\u00e9es d\u2019observation de la Terre du 22 octobre 2001 jusqu’\u00e0 la fin de la phase op\u00e9rationnelle de la mission, en d\u00e9cembre 2022. Le satellite est toujours fonctionnel, \u00e9tant utilis\u00e9 pour tester des algorithmes. C\u2019est actuellement le satellite d\u2019observation de la Terre de l\u2019ASE qui a eu la plus longue long\u00e9vit\u00e9 en orbite.<\/p>\n

NGC est fier d\u2019avoir particip\u00e9 au succ\u00e8s de la mission de PROBA-1 et d\u2019avoir contribu\u00e9 \u00e0 ses objectifs de d\u00e9monstration et d\u2019\u00e9valuation en orbite de l’autonomie op\u00e9rationnelle \u00e0 bord. Ce succ\u00e8s a contribu\u00e9 \u00e0 plusieurs autres satellites, dont PROBA-3, lanc\u00e9 en d\u00e9cembre 2024, et la s\u00e9rie des trois satellites Sentinel-3, dont le plus r\u00e9cent satellite a \u00e9t\u00e9 lanc\u00e9 en septembre 2026.<\/p>\n
