Abstract

Improving the robustness and accuracy of strap-down north finder is a hot topic and difficult problem due to the complexity and randomness of environmental disturbance. The paper presents a data processing method composed of the wavelet compulsory decreasing noise and statistical subsection method according to the characters of its working environments. The practical data and processing results show that the method presented is effective for eliminating dynamic disturbance.
