Gyrometers and gyroscopes. Gyrometers measure the angular velocity. Such measurement is based on the measure of Coriolis forces for a mobile in linear motion, when an additional rotation occurs... Gyroscopes are made of a solid body with high angular velocity around an axis of symmetry... which induces a high angular stability in presence of perturbations. Such a device is used to preserve a fixed inertial orientation, while the rest of the system in in motion. It must be noted that both devices provide an information about angular velocity. The first device output is the instantaneous angular velocity, while the second device output is the integration of the angular velocity during a period of time. Angular position information can be computed from gyrometers output by integration, while angular velocity information can be computed from gyroscopes output by derivation. 2, record 1, English, - instantaneous%20angular%20velocity

If in a gravitational field you support a rotating body in only a single point that is not the center of gravity(center of mass), there is a torque acting on it; if the rotation is fast enough to be associated with a substantial angular momentum and the change in angular momentum effected by that torque is comparatively small, you will observe precession. Gyroscopes used for navigation have to be suspended in their center of gravity and in a way that when changing direction of the box(airplane) around it no torque is applied through that suspension. 2, record 2, English, - gyroscope%20suspended%20off%20center%20of%20gravity
