Abstract

Based on the analysis of the demand of low cost, low weight and high reliability of seeker,MEMS gyro is developed to be used in half-strapdown stable platform.For gyro,the dynamic change of bias and scale factor can be caused by the change of internal temperature,external environment and various stre- ss.Accurate output of gyro is crucial to the halfstrapdown stable platform ,a method using an adaptive echo canceller to identify the change of bias and scale factor is discussed,so as to improve the output preci- sion of the gyro and enhance the seeker pointing accuracy.At the end,simulation experiments are performed and the effectiveness of the proposed method is verified.
