Place of Origin:
China
Brand Name:
Liocrebif
Certification:
GJB 9001C-2017
Model Number:
LKF-FS70
Introduction
Fiber optic gyro, as a new type of all-solid-state gyro, has the advantages of fast startup, wide measurement range and high reliability, etc. LKF-FS70ZK can be applied to the application requirements of medium and high precision inertial guidance system which can be applied to land positioning and orientation, vehicle-mounted north finder, airborne air posture, marine gyro compass and so on.
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.The miniatured fiber optic gyros have excellent advantages of compact and cost-effective, and are easy to integrate and ideal for UAV, photoelectric pod, optical platform, and so on.
