Gyroscopes are used in many inventions both old and new to stabilize, guide or measure rotational movement. Wheels on a bicycle, for example, act as gyroscopes as they spin up to speed, making it easier to stay upright and harder to upset momentum. Guided missiles use gyroscopes to track and guide their courses.

Altering the direction of a device with a gyroscope is achieved by rotating the gyroscope, changing its axis of output force. The measured rotation of multi-axis gyroscopes through sensors enables accurate measurement and guidance of many devices.
