| Abstract: | The standard Kalman filter cannot be used exactly when some parameters of integrated navigation system are not precisely known or gradually changed with time. Acoording to the principle of adaptive filtering analysis, a method of adaptive factor construction with uncertain parameter based on interval math is proposed.As the interval of uncertain parameter is known, the estimation of interval of adaptive factor is discussed. The method is examined by using the GPS/INS integrated navigation system developed by authors. The results show that the proposed method is effective. |
