Fiber Optic Gyroscope Output Signal Processing Based on Multiwavelet Denoising

The effect is limited that in single-wavelet noise reduction. A new multiwavelet denoising method is available to inhibit the noise interference in the gyroscope output signals of an inertial navigation system. It will be an important Breakthrough that the vector of initial azimuth and attitude angle are determined quickly and correctly in the inertial navigation system. The sampling data reducing noise in miniature strap-down inertial navigation system can be simulated in MATLAB. Results attest the engineering value of multi-wavelet noise reduction in favor of the useful signals retained.
