Abstract :
Dynamically tuned gyroscope (DTG) is used more and more wildly in inertial navigator, so it is significant to eliminate the gyro random drift and noise in order to increase the precise of the DTG. The DTG error characteristics and mathematic model were presented, a fast algorithm based on translation invariant discrete wavelet transform (TIDWT) was used with a new thresholding function, the signal sampled in dynamic disturbance are processed by this method, and the validity is verified through a experiment.
