What Is a Fiber Optic Gyro and Why Is It Essential for Modern Navigation Systems?
A Fiber Optic Gyro (FOG) is a high-precision inertial sensor that measures angular velocity using optical interference based on the Sagnac effect. With no moving parts, it delivers low drift, high accuracy, and strong environmental robustness. This article explains Fiber Optic Gyro principles, key performance parameters, and typical applications, supported by a high-performance single-axis digital Fiber Optic Gyro specification example.
