Model Number:
LKF-F3X50
Introduction
LKF-F3X50 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.
Earthquakes are a devastating natural disaster, so early warning and accurate seismic measurements are crucial. The high accuracy and sensitivity of the LKF-F3X50 fiber optic gyroscope make it an indispensable part of the earthquake monitoring network.
