Angular rate gyro accuracy is characterized by two parameters: scale factor and drift. The scale factor describes the capability of the gyro to accurately sense angular velocity at different angular rates ... Gyro drift characterizes the ability of the gyro to reference all rate measurements to the nominal zero point. It appears as an additive term on the gyro output, so any actual drift away from a given or predetermined value will cause the angular errors to accumulate. 3, record 1, English, - gyro%20drift

The free gyro... can be converted to a directional reference by remounting its case with the spin axis horizontal and the indicator axis vertical. The indicator will then give the airplane's heading. Gyro drift is countered by slaving the instrument to the Earth's magnetic field, via either a separate magnetic compass or a flux valve device. 5, record 1, English, - gyro%20drift

The change in azimuth (direction) of the spin axis is often referred to as "drifting": sometimes "tilting" and "drifting" are collectively called "apparent wander." 4, record 1, English, - gyro%20drift

Le défaut de stabilité, appelé dérive du gyroscope mesurée en degrés par heure [...], ou en degrés par seconde [...], dépend de la technologie mise en œuvre et de la qualité de la «suspension» de l'élément sensible et de son isolement vis-à-vis des influences externes (température, gravité, gaz ambiant, etc.). 4, record 1, French, - d%C3%A9rive%20du%20gyroscope

Pour l'utilisation sur les centrales inertielles, il s'est révélé nécessaire de développer des gyroscopes présentant une dérive pratiquement négligeable. Or la cause principale de cette dérive réside dans les frottements qui s'exercent sur le corps du gyroscope, dont la vitesse de rotation dépasse 20 000 tr/min. Divers moyens ont été imaginés pour créer des suspensions sans frottement [...] 5, record 1, French, - d%C3%A9rive%20du%20gyroscope

Bakanae is caused by the fungus Fusarium. While it is generally thought of as a seedling disease, it can be observed throughout the growing season. Infected seedlings are taller and more slender and are often visible arching above the healthy rice plants. As the season progresses, bakanae-infected plants may die before reaching maturity, or if they survive to heading, the panicles they produce are mostly empty. The fungus can over winter in the soil and residue as spores on the coat of infested seeds, leading to infected plants in the field the following season. 7, record 2, English, - Bakanae%20disease

Laser Position Measurement. A commercially available position measuring device, Lasernet, was donated by the Namco Controls Corporation. A single narrow-beam laser is continuously swept across the field at a fixed height. A reflector of known geometry on the vehicle reflects the beam back to the device, which reports the initial angle, in the local geographic frame, at which a reflection is detected and the angular width over which the reflection is continuously detected. Knowing the geometry of the reflector, which should be independent of the heading of the aircraft, is sufficient to determine the vehicle's two-dimensional position in the local geographic frame. 1, record 3, English, - position%20measuring%20device

La centrale à inertie est un appareil de mesure du positionnement très utilisé en raison de son autonomie et de sa faible sensibilité aux perturbations externes. On en trouve à bord des avions de ligne, des sous-marins, ou des missiles intercontinentaux.

Sur les petits appareils comme le Cessna 182RG, le pilote règle le conservateur de cap pour qu'il coïncide avec le compas avant le décollage, et le réajuste périodiquement pendant le vol pour être sûr qu'il reste synchronisé avec le compas. Le conservateur de cap dérive parce qu'il est basé sur un gyroscope, sujet avec le temps à la précession. En règle générale, le conservateur de cap ne doit pas dériver de plus de 3 degrés toutes les 15 minutes. Les appareils plus importants sont équipés de conservateurs de cap asservis qui maintiennent l'instrument correctement aligné avec le compas. 3, record 4, French, - asservissement
