CONT

Principe d'une centrale inertielle [...] Mesure de la rotation [...] La plateforme [...] étant stabilisée en permanence, des capteurs angulaires (potentiomètres [...]) et des capteurs de vitesse angulaire (génératrices tachymétriques [...]), disposés sur les articulations des armatures de Cardan [...] mesurent en continu les angles d'orientation [psi, thêta, phi] et leur vitesse angulaire. Nous confirmons ainsi la possibilité de mesurer notamment le vecteur rotation absolu du véhicule dans un repère galiléen. Une des affirmations du principe d'Einstein-Galilée est donc vérifiée.
