SINGLE AXIS FIBER GYRO LOW BIAS GYRO CLOSE LOOP GYRO The F70 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 F70 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 military and
industrial applications. F70is a angular speed sensor integrated
with light, mechanism and eletricity. it is based on Sagnac ef fect
and close loop control test technology. it tests, processes and
feedbacks by the phase difference p roduced 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 structur e, no moving parts, no
wearing parts, quicker start, smaller volume and ligher comparing
with electrom echanical gyro. It could be widely used in missile
guidance and control, positioning and aiming system of tank and
fighting vehicle, ship's photoelectrical tracking syste - Higher accuacy with smaller size
- High-speed rail track detection, photoelectric pod, moving pass,
