The compensation method for MEMS gyro random drift error is discussed. Based on the fundamental theories of wavelet analysis for signal de-noising, an improved wavelet threshold de-noising method incorporating the polynomial interpolation function is presented for compensating the MEMS gyro output noise. The measurement data of MEMS gyro is analyzed, and the result proves that the proposed method performs well for MEMS signal de-noising.
