Application of fiber optic gyroscope

1 Navigation applications

The compass is an important navigation device for ships, mainly including magnetic compasses and gyrocompasses. With the development of fiber optic gyroscope technology and the improvement of commercialization level, fiber optic gyroscope has become a new member of marine navigation equipment, and has been applied in commercial and military vessels and marine equipment. The fiber-optic gyroscope based on the Strapdown Inertial Navigation System corresponds to the three axes of the ship coordinate system. It can be used not only as a source of high-precision heading, but also to automatically find the north and north. Reliable data such as heading slew rate, transverse and pitch angles, and heading rotation rate further promote the automation of the ship, ensuring the ship’s handling effect and ensuring navigation safety.

2 Aerospace and space applications

High-precision interference fiber optic gyros are generally used in aerospace and space applications. IFOG is the strapdown inertial navigation system of the main inertial components. It can provide three-dimensional angular velocity, position and angle of attack and side slip angle for the aircraft. It can track and measure the launch of rockets. It can also be used for spacecraft stability, photography/measurement, attitude. Measurement control, motion compensation, EO/FLIR stabilization, navigation and flight control, etc. Among them, the high-precision and high-reliability fiber optic gyroscope and GPS combination attitude has become the typical configuration of spacecraft attitude and attitude systems at home and abroad.
