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.
