| Abstract: | An effecitive reduced order Kalman filter for the integrated GPS and platform inertial navigation system , which is used in some aircraft ,is presented . ln this paper ,the equations of the reduced order filter are given , and the pseudorandom niose of the model error compensation method is studied .On the other hand ,by error analysis of the reduced order filter and computer simulation , we see that the presented reduced order filter can ensure accuracy of integrated navigation system .According to the research ,the scheme of integrated navigation system with the reduced order filter has great use value. |
