1 Introduction
fiber optic gyroscope as a new type of all-solid-state gyroscope, has the advantages of fast start-up, wide measuring range and high reliability. F50 single-axis low and medium precision fiber optic gyroscope can be applied to the application requirements of medium and high precision inertial guidance systems such as land-based positioning and orientation, vehicle-mounted north finder, airborne heading, and marine gyroscope compass.
