Fiber optic gyroscope, as the core component of inertial navigation system, can provide high-precision three-dimensional angular velocity, position and attitude information in the aerospace field, realizing functions such as tracking and measurement of rocket launch, spacecraft stabilization, attitude measurement and control. In the field of navigation, fiber optic gyroscopes have become an important component of ship navigation equipment, providing high-precision heading information and achieving functions such as automatic north finding and pointing, attitude control, etc.

Fiber optic gyroscope is an inertial sensor based on fiber optic technology, used to measure and detect rotational speed and direction.
