CONT

Équations de la gyroscopie [...] Mémorisation : C'est le premier usage d'un gyroscope monté à la Poinsot. Il permet la mémorisation d'une direction absolue stellaire. Ainsi en mémorisant 2 directions de l'espace (la troisième étant le produit vectoriel des 2 autres), pointant 2 étoiles parfaitement connues, on peut donc disposer à bord de tout véhicule, d'un repère de référence absolu. Cette application est essentielle pour les voyages interplanétaires, les vols sans visibilité, les missions des sous-marins etc.
