OBS

OBS

Le gyroscope «1 axe» à suspension hydrostatique [...] Exemple d'application : le chercheur de nord Teldix NSK 40. Il s'agit essentiellement d'un gyroscope GWK 281 équipé d'un rappel élastique le transformant en gyromètre, dont le boîtier est suspendu au cardan de manière à pouvoir : obtenir l'alignement de son axe de sortie avec la verticale locale, par effet pendulaire; subir une rotation quelconque autour d'un axe d'azimut, sensiblement vertical, lié au boîtier de l'ensemble. La recherche du nord est effectuée par un asservissement dont l'élément détecteur est le gyromètre (axe d'entrée E), et dont le moteur agit sur sa suspension, de manière à faire balayer le plan horizontal par E.
