LKF-F3G80 inertial measurement unit is an inertial product developed for navigation guidance, 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.

When the GPS signal is poor, the LKF-F3G80 can continue to conduct precise navigation based on the known bearing, direction and speed. This is also the basic principle of inertial navigation technology. At the same time, it can also correct the problem of excessive positioning deviation when the GPS signal is not good.
