Fiber optic gyroscope has no rotating or friction components, therefore it has high stability and reliability. This all solid state structure reduces errors caused by factors such as mechanical wear and vibration. Fiber optic gyroscope can maintain good stability under long-term operation, which is particularly important for application scenarios that require long-term navigation and positioning.

The development of fiber optic gyroscopes faces some technical difficulties, such as sensitivity loss, drift caused by noise and fiber birefringence, and unstable scaling factor caused by polarization state changes. In order to overcome these difficulties, researchers are constantly exploring new technologies and methods, such as using high birefringence fibers and optimizing fiber optic wrapping techniques. In the civilian field, fiber optic gyroscopes are mainly used for automatic navigation, positioning and orientation, vehicle control of ground vehicles, as well as attitude control of agricultural aircraft, positioning tools and rescue tools in underground engineering maintenance.
