Gyroscope
A gyroscope is a device that uses the principle of angular momentum to measure or maintain orientation. In spacecraft, gyroscopes are used to provide attitude control and stabilization, allowing the spacecraft to maintain a desired orientation in space. They are also used in navigation systems to measure changes in orientation and calculate the spacecraft's position and velocity. Gyroscopes can be mechanical, optical, or based on micro-electromechanical systems (MEMS) technology. Mechanical gyroscopes use a spinning mass to maintain orientation, while optical gyroscopes use the interference of light waves to measure changes in orientation. MEMS gyroscopes use tiny vibrating structures to detect changes in orientation. Gyroscopes are critical components in spacecraft and are used in a variety of applications, including satellite communication, Earth observation, and deep space exploration.
