Model Number:
LKF-F3G40
Introduction
F3G40 3-axis FOG is an inertial product developed for inertial navigation, attitude measurement and control systems of small missiles and guided bombs. The angular velocity and linear acceleration of the carrier motion provide information for the attitude and navigation control of the carrier, and the measurement results are output through the RS422 serial port.
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.
The three-axis fiber-optic gyroscope can provide high-precision attitude angular velocity data to help the UAV achieve accurate attitude control and navigation. By monitoring the UAV's 3D rotational motion in real time, the gyroscope data can be fused with GPS and other sensor data to ensure the stability and accuracy of the UAV in flight.
