Current State and Development Prospects of Fiber-Optic Gyroscopes

The paper studies the current state of fiber-optic gyroscopes (FOG) development. An overview of the modern market of gyroscopes for inertial navigation is presented with a special focus on the FOG niche. The principle of operation is briefly described; classification of existing FOGs is presented; their advantages and disadvantages are discussed; and some examples of existing devices are given. Key Russian and international manufacturers are mentioned in the paper. Finally, trends of FOG development are observed, and the future development of the gyroscope market is assessed.
