abstract:A fibre optic gyroscope (FOG) senses changes in orientation, thus performing the function of a mechanical gyroscope. However its principle of operation is instead based on the interference of light which has passed through a coil of optical fibre which can be as long as 5 km.
Considering thedirectangularvelocitysignal output from fibre opticgyroscope, anovelconingcompensationalgorithm wasintroduced and it need inputangular velocity signal.
