As the aircraft approaches the poles (90°), cos [phi] approaches zero, so that the computation of longitude leads to a singularity. Consequently, a physical limitation arise in the computation of the azimuth gyroscope torquing command. That is, the rate at which the inertial platform must be rotated about the vertical axis in order to maintain one of its level axes pointing north (this is the so-called "north-slaved" system; ... 1, record 1, English, - north%2Dslaved%20system

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. 2, record 1, French, - syst%C3%A8me%20chercheur%20de%20nord

A gyrocompass must not be confused with a directional gyro. The latter is a gyroscope which is slaved to a magnetic compass and is not itself a north-seeker. Most conventional aircraft are equipped with north-slaved directional gyros. 1, record 2, English, - north%2Dslaved%20directional%20gyro

... inertial platform control implies the continuous orientation of the gimbal system (cluster) to some predetermined reference frame, after an initial alignment. Platform heading can be maintained through signals to the gyroscope torquers originating in the navigation computer. For example, in a north-slaved platform, the gimbal cluster must be rotated in azimuth. 1, record 3, English, - north%2Dslaved%20platform

Generically, gyros fall into two broad classes. They will either maintain a known direction by resisting acceleration present when turning, such as the type of gyrocompass often found in airplanes, or they actually indicate the orbital axis of the earth providing a reference of geographic or "True" north, such as a north-seeking gyro in a ship. 6, record 4, English, - north%2Dseeking%20gyroscope
