| Abstract: | A simplified adaptive Sage Husa filter is discussed. Generally the method of increasing the adaptive ability of normal Kalman filter is to do optimal estimation of the statistical feature of measurement noise and inteference. This way the complication of filter is enhanced also. This influences the real time chasasteristics of the filtering. The simplified Sage Husa filter can solve this problem partly because of its simple structure. The result of computer simulation shows the simplified filter is useful, effective and adaptive when it is applied in the ship integrated navigation system. |
