The paper deals with the effects of the angle random walk and engine jamming on SINS alignment. An algorithm is proposed which is based on the interval wavelet transform and forward linear prediction. The algorithm uses forward linear prediction and the ability of the interval wavelet transform to restrain terrible edge effects, thus, the angle walk and engine jamming are reduced effectively. The results prove the feasibility of the method.
