High Bandwidth Fiber Gyro Sensor

High Bandwidth Fiber Gyro Sensor 

DESCRIPTION:
The F70G is the interferometric digital close-loop single-axis fiber optic gyro. It is the perfect substitution for traditional mechanical gyro, featuring of high bandwidth, short activation time, shock resistance, vibration resistance and affordable cost.
The F70G FOG adopt the embedded digital signal processor. The integrated adaptive filter reduces the bias stability and angle random walk by 50%-70%,technology which not only reduces the impact of the temperature but also significantly improves the bias stability, angle random walk, scale factor linearity and robustness. The exceptional bias stability, angle random walk and resistance to shock make it ideal for various industrial applications.
F70G is a angular speed sensor integrated with light, mechanism and eletricity. it is based on Sagnac effect and close loop control test technology. it tests, processes and feedbacks by the phase difference produced by two oppsite transmission light, realising the whole close loop process.
the item is mainly composed by optical path units, circuit units and structural unit. it has simpler structure, no moving parts, no wearing parts, quicker start, smaller volume and ligher comparing with electromechanical gyro. It could be widely used in missile guidance and control, positioning and aiming system of tank and fighting vehicle, ship's photoelectrical tracking system

FEATURES:

All-fiber design -long lifespan, small package size, high stability and more resistance  to interference.
Integrated fiber polarizer -minimum insertion loss and high extinction ratio, offering more resistance to temperature and mechanical shock, as well as intense vibration. Reliable compact package -operationally robust for all kinds of environments, ideal for a wide of applications in civilian industy
QuichLaunch technology -minium activation time with no external calibration required.
Optimal wavelength -improves the sensibility by 50% with the same structure, size and cost.
Noise isolation and compression -significantly reduces the angle random walk.
SelfTrack technology -improves the gyro dynamic range              

APPLICATIONS:
UAV/AUV/Helicopter    
Tactical nuclear weapons    
Aeronautics and astronautics
Integrated navigation system    
inertial platform stabilizing  
Vehicle navigation
