DEF

cardan's suspension: An arrangement of rings in which a heavy body is mounted so that the body is fixed at one point; generally used in a gyroscope.

DEF

gimbal: A mechanical frame that permits an object mounted onto it to remain in a stationary position regardless of the movement of the frame.

CONT

... 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.

CONT

In the conventional gimbaled system, the platform contains three single-degree-of-freedom, or two two-degree-of-freedom gyroscopes, three linear accelerometers, and their associated electronics.

CONT

Inertial navigation system (INS)... Velocity and distance are computed from sensed acceleration. Two accelerometers, gyro stabilized, are mounted in a gimbal assembly, commonly called the platform. One measures acceleration in the north-south direction and the other in the east-west direction.

OBS

gimbal mount: term officialized by the Aeronautical Terminology Standardization Committee (ATSC) - Helicopters.

DEF

cardan; suspension à la cardan : [...] mode de suspension tel que le corps suspendu [...] conserve une position horizontale malgré les oscillations du support. Elle est employée principalement à bord des navires, des avions, pour les compas et les chronomètres.

CONT

Système de navigation par inertie [...] La vélocité et la distance sont calculées à partir des accélérations détectées. Deux accéléromètres, stabilisés gyroscopiquement, sont montés sur un système de cardans appelé communément une plate-forme. L'un mesure les accélérations détectées sur un axe orienté nord-sud et l'autre, sur un axe orienté est-ouest.

OBS

cardan : Abréviation de suspension [...] à la cardan.

OBS

suspension à la cardan : terme uniformisé par le Comité d'uniformisation de la terminologie aéronautique (CUTA) - Opérations aériennes.

suspension à cardan : terme uniformisé par le Comité d'uniformisation de la terminologie aéronautique (CUTA) - Hélicoptères.
