A control moment gyroscope (CMG) is an attitude control device generally used in spacecraft attitude control systems. A CMG consists of a spinning rotor and one or more motorized gimbals that tilt the rotor’s angular momentum. As the rotor tilts, the changing angular momentum causes a gyroscopic torque that rotates the spacecraft. [ 1 ][ 2 ]
A gyroscope (from Ancient Greek γῦρος gŷros, "round" and σκοπέω skopéō, "to look") is a device used for measuring or maintaining orientation and angular velocity. [1][2] It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself. When rotating, the orientation of this axis ...
An inertial navigation system (INS; also inertial guidance system, inertial instrument) is a navigation device that uses motion sensors (accelerometers), rotation sensors (gyroscopes) and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object ...
Another difference between shawarma and gyro is the preparation; shawarma is more about the flavor of the meat than the plethora of toppings on it. Shawarma is carefully marinated all day in ...
Ring laser gyroscope. A ring laser gyroscope (RLG) consists of a ring laser having two independent counter-propagating resonant modes over the same path; the difference in phase is used to detect rotation. It operates on the principle of the Sagnac effect which shifts the nulls of the internal standing wave pattern in response to angular rotation.
Hemispherical resonator gyroscope. The hemispherical resonator gyroscope (HRG), also called wine-glass gyroscope or mushroom gyro, is a compact, low-noise, high-performance angular rate or rotation sensor. An HRG is made using a thin solid-state hemispherical shell, anchored by a thick stem. This shell is driven to a flexural resonance by ...

Gyros, sometimes anglicized as a gyro [2] [3] [4] (/ ˈ j ɪər oʊ, ˈ dʒ ɪər-, ˈ dʒ aɪ r-/; Greek: γύρος, romanized: yíros/gyros, lit. 'turn', pronounced) in some regions, is meat cooked on a vertical rotisserie, then sliced and served wrapped or stuffed in pita bread, along with other ingredients such as tomato, onion, fried potatoes, and tzatziki.
