Stabilisation and orientation by inertial flywheels consists in accurately aligning the axes of three flywheels with the axes of reference(roll, pitch and yaw)... The spherical orienter... uses the principle of inertial reaction. It consists essentially of a floating sphere supported electrostatically, magnetically or by an air cushion. This sphere can thus turn freely about any axis, friction being negligible. If the stator... exercises a couple on the sphere, it responds to this stress by an equal and opposite reaction couple, until it has attained its limiting speed or rotation(saturation). 1, record 1, English, - spherical%20orienter

[...] le télescope spatial Hubble connaît [...] des ennuis mécaniques. Son système d'orientation dans l'espace, composé de six gyroscopes, semble moribond. Déjà, deux des gyroscopes sont hors service alors qu'un troisième serait sur le point de tomber en panne. Hubble a besoin d'au moins quatre gyroscopes pour s'orienter dans l'espace et poursuivre ses observations astronomiques. 2, record 1, French, - syst%C3%A8me%20d%27orientation%20gyroscopique

Un gyroscope est un disque ou, dans ce cas-ci, une sphère qui tourne sur un axe. Une fois en rotation, l'axe continuera toujours à pointer dans la même direction si aucune autre force ne vient altérer son mouvement. 3, record 1, French, - syst%C3%A8me%20d%27orientation%20gyroscopique

The main AI [attitude indicator] used an electrically driven, two axis of freedom, vertical gyroscope assembly... Attitude information was displayed by a sphere which was mechanically driven by the pitch gimbal and directly attached to the roll gimbal of the vertical gyroscope. Movement of the roll and pitch gimbals registered roll and pitch axis sphere movement in relation to a miniature airplane symbol. A roll index, attached to the roll gimbal, indicated the roll displacement angle relative to a frame mounted roll scale. Pitch displacement angles were displayed on the sphere. 2, record 2, English, - pitch%20gimbal

Centrale de cap et de verticale pour avion. Une centrale est constituée d'un gyro-indicateur de verticale et d'un gyroscope directionnel garde-cap. La direction par rapport au nord du moment cinétique du gyroscope directionnel est repérée juste avant le départ de l'avion à l'aide d'un gyroscope de transfert. Un gyroscope de verticale asservit une plate-forme autour de deux axes parallèles aux axes de roulis et de tangage de l'avion. Cette plate-forme délivre les références de roulis et assiette longitudinale et supporte un gyroscope directionnel qui fonctionne en garde-cap. La plate-forme asservie est constituée d'un cadre de roulis extérieur et de deux cadres de tangage liés mécaniquement.
