摘要
The data processing methods are applied to improve the accuracy of strap-down north finder for vehicles when north finder is subject to some external disturbances. The north-seeking principles of strap-down north finder and reasons for causing errors by external disturbances are analyzed in detail. Low pass filtering method and two types of statistical subsection methods are presented. The experimental data and simulation results show that the methods presented are very practical and effective to reject some external disturbances and to improve the accuracy of strap-down north finder.
