Compass settling is very slow(>10s), is affected by magnetic fields from the vehicle motors, and will require that the vehicle stop to take an accurate reading. We hope to monitor vehicle turns using the yaw gyro over short time intervals, resetting the gyro with the compass periodically. 2, record 1, English, - continuous%20resetting

DI - direction indicator. A gyro instrument which indicates the magnetic heading of an aircraft. The DI ... is free of the turning errors associated with magnetic compasses but is prone to precession (wander) and must be reset against the magnetic compass at intervals. 3, record 1, English, - continuous%20resetting

Les gyroscopes sont soumis à des dérives qui conduisent à un mésalignement des axes plateforme par rapport aux axes absolus. Les accéléromètres présentent des erreurs de linéarité de seuil, de biais qui augmentent les erreurs de la centrale [inertielle]. Pour les missions spatiales, le problème est résolu en observant : [...] que les dérives ont peu d'effet sur des temps courts. [...] Pour des missions longue durée ou à grandes distances comme [les] missions interplanétaires, une navigation stellaire permet d'actualiser la position et la vitesse du véhicule, avant une manœuvre. Pour les avions, les vols sont de plus longue durée, du moins pour les avions civils, et un recalage permanent est effectué [...] 2, record 1, French, - recalage%20permanent

gyromagnetic compass: A directional gyroscope whose azimuth scales is maintained in alignment with the magnetic meridian by a magnetic detector unit. 1, record 2, English, - gyromagnetic%20compass

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 2, English, - gyromagnetic%20compass

Le compas gyromagnétique ou gyrosyn. [...] le conservateur de cap ou compas gyroscopique est un instrument stable mais qui ne fournit pas d'indication de cap magnétique. Son recalage en azimut doit se faire manuellement. Inversement, la vanne de flux fournit une indication précise de cap mais est instable. En associant ces deux instruments, on obtient un compas gyromagnétique qui fournit une indication de cap tout en étant stable. [...] Les compas gyromagnétiques se composent d'un conservateur de cap avec un système d'érection en site, d'un élément détecteur de la composante horizontale du champ magnétique terrestre, d'un système détecteur d'erreur qui compare en permanence le cap gyro et le cap magnétique. 6, record 2, French, - compas%20gyromagn%C3%A9tique
