Exhaust thrust deflection control. Another method of stabilisation comprises a gyroscope unit which detects deflections and converts them into electrical signals, which are injected into a computer carried on board the spacecraft. The computer compares the measurements taken from a programmed trajectory and deduces the correction instructions needed. 1, record 1, English, - gyroscope%20unit

Gyro de transfert. La grande problématique du navigateur était de décoller avec un cap vrai le plus précis possible pour se garantir une navigation sans trop d'histoires. Il avait été imaginé un conservateur de cap installé dans une Renault 4L qui stationnait près du bureau de piste. Avant chaque départ en mission la 4L était utilisée pour caler la centrale gyroscopique du Mirage IV au moyen du gyro de transfert prévu à cet effet dans son coffre. Cette solution assez contraignante a été abandonnée lorsqu'il est apparu que le calage manuel de la centrale, avion aligné sur l'axe de piste, était d'une précision suffisante. 5, record 1, French, - centrale%20gyroscopique

Two accelerometers, gyro stabilized, are mounted in a gimbal assembly commonly called the platform ...

Comment stabiliser un solide (plate-forme)? : Précisément au niveau des axes des anneaux supplémentaires, on peut mesurer les rotations infinitésimales du solide par rapport aux gyros fixes par rapport aux étoiles. La détection d'un écart angulaire traitée par un asservissement adéquat, commandera l'action d'un moteur qui annulera l'écart angulaire. Ainsi les axes plate-forme resteront toujours alignés sur ceux des gyros. C'est la notion de plate-forme stabilisée. 7, record 2, French, - plate%2Dforme%20gyrostabilis%C3%A9e

[...] les systèmes inertiels [...] font appel à une autre loi de la physique selon laquelle les objets tournant à très haute vitesse garderont leur position relative dans l'espace. En d'autres termes, si on se met à faire tourner un objet (une toupie, par exemple) à un rythme effréné, il ne tombera pas. Conséquemment, les systèmes inertiels se composent d'un minimum de deux gyroscopes, chacun desquels supporte une masse globulaire placée à l'intérieur d'un cardan. On tient cependant les appareils d'aujourd'hui en suspension électromagnétique afin d'en réduire la friction. On orientera l'un des gyroscopes à la verticale tandis que le second y sera annexé à angle droit. Un objet tournant à la quasi-verticale s'orientera à la verticale réelle grâce aux effets de gravité. [...] S'il y a inclinaison de la plate-forme, comme par exemple lors d'un virage sur l'aile, le cardan s'incline en tandem avec l'avion tandis que la masse tournante demeure à la verticale. On peut dès lors mesurer l'angle d'inclinaison. 13, record 3, French, - cardan
