The gyrosyn compass combines the functions of both the directional gyro and the magnetic compass. It provides stable compass headings in rough air, is north seeking like a magnetic compass, but is free from northerly turning error and oscillation. It does not precess and, therefore, does not require resetting as does the directional gyro. The gyrosyn compass system incorporates a flux valve that senses the earth’s magnetic lines of force through electromagnetic induction. 6, record 1, English, - gyromagnetic%20compass

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 2, French, - centrale%20gyroscopique

The first type of gyroscopic instrument to successfully reduce gimbal bearing friction to an acceptable level for precision applications was the floated gyroscope. In this instrument the rotating member is sealed within a hollow cylinder which forms the inner gimbal of the gyro. This is mounted in the gyro case whith a fluid surrounding the cylinder; the density of the fluid is chosen so as to exactly float the cylinder, thus removing the weight of the inner gimbal from the bearings and greatly relieving the bearing frictional load. 2, record 3, English, - floated%20gyroscope

Le gyroscope [...] baigne dans un liquide très visqueux, à une température de l'ordre de 60 à 80 °C, dont le rôle est double : 1- La viscosité importante sert d'amortissement 2- La densité est telle que ce liquide de flottaison donne une poussée d'Archimède qui équilibre le poids apparent. Ce qui réduit les efforts d'appui sur les paliers et donc les couples de frottement. Un tel dispositif porte bien son nom de gyroscope flottant. 4, record 3, French, - gyroscope%20flottant

[...] 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.
