Summary:The navigation system and its initial alignment method for autonomous undersea vehicle(AUV) is studied in this paper because AUV has the special need towards navigation and its initial alignment method. First, the crucial error factor is deep analyzed when AUV have angle movement and linear movement. Secondly, four-order gyrocompass loop is designed which has strong anti-jamming characteristic by method of perturbation. At last the effectiveness of the alignment method is validated by computer simulation, swing experiment and moor experiment.
