Model Number:
LKF-FS50X
Introduction
LKF-FS50X is a miniaturized closed-loop fiber optic gyroscope, which breaks through the classical design concept of traditional fiber optic gyroscope. It adopts integrated circuit and optical path design. It has the outstanding characteristics of small volume, light weight, high bandwidth, fast start-up, simple interface and convenient use. LKF-FS50X is an ideal medium-low precision angular rate sensor in the control field, which is widely used in various inertial measurement and control fields.
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.
By using inertial devices and strapdown inertial navigation technology, accurate speed, position and attitude information can be provided for the UAV, thereby achieving precise navigation, positioning and attitude control. LKF-FS50X can greatly improve the performance of inertial navigation and is an ideal choice for medium-low precision inertial navigation.
