Introduction

LKF-F3G90 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.

As oil resources become increasingly depleted and exploration and development situations become more complex, gyroscopes and inertial navigation systems with higher precision and more reliable performance are needed to accurately measure engineering parameters during the drilling process.
