Abstract
Cet instrument comprend un gyrostat de stabilisation 1 et un gyrostat de contrôle 2 montés sur un arbre de commande 3, le rotor du gyrostat de stabilisation étant monté rigidement sur l'arbre par des moyens qui permettent à son axe polaire de s'écarter d'un petit angle de la colinéarité avec l'arbre de commande De préférence, le moment cinétique du gyrostat de contrôle est petit en comparaison de celui du gyrostat de stabilisation. L'axe d'oscillation libre est utilisé pour maintenir l'orientation moyenne des axes de couple du gyrostat de contrôle dans leurs positions correctes, c'est-à-dire verticalement et horizontalement. Cela est particulièrement important à l'usage sur un navire lorsque celui-ci prend de la gîte à babord ou à tribord.
