Introduction
Fiber optic gyro, as a new type of all-solid-state gyro, has the advantages of fast startup, wide measurement range and high reliability. Among them, LKF-F3X100-IMU type fiber optic gyro inertia set is designed for the needs of medium and low precision application background, adopting three-axis shared technology design, low cost and stable performance; the structure adopts the integrated package of optical circuit and circuit, simple structure, easy installation, and it can be applied in the system of navigation and guidance, attitude measurement and control of small missiles, guided bombs, and so on.
By reducing the outer diameter of fiber to 135μm,Thin PM fiber solution decreases extremely the size of fiber coils and delivers outstanding precision performance in fiber coils, which is applied for miniaturization of FOGs. And, the coils are wound precisely through quadrupole symmetry method.
Aerospace Applications In aerospace applications, high-precision interferometric fiber optic gyroscopes are generally used. The LKF-F3X100-IMU fiber optic gyro inertial unit can provide the aircraft with three-dimensional angular velocity, position, angle of attack and sideslip angle to achieve tracking and measurement of rocket launches.
