ABSTRACT:
A least-mean-squares based algorithm is used to adaptively update dither stripper gains, in a dither stripper of a ring laser gyro. The algorithm is used in conjunction with a dither estimator of the dither stripper. The dither stripper substantially reduces effects of dithering a ring laser gyro, during operation of the ring laser gyro.
