Abstract:In modern air warfare,independent use of strap down inertial system(SINS), global position system(GPS) and tactical air navigation system(TACAN) has disadvantages. In this paper the airborne integrated navigation system is proposed based on these three navigation equipment. The information fusion is accomplished by using federated filtering technology, choosing the error of navigation parameter as the state vector, and constructing the mathematics model of state equation about integrated system. Each of sub filters gains an estimation of state vector by using work method of indirect filter.Primary filter accomplishes the fusion of public state vectors about sub filters and time updating, and outputs the credible, precise and optimal estimation of navigation parameter error. Using the output of the whole filter as means of closed loop of feeding back, correct inertial navigation parameter, dynamic calibration(reinstalling the integral initial condition of specific force equation),dynamic alignment(reinstalling the integral initial conditions of attitude matrix differential equations), dynamic demarcation are realized, so that the performance of integrated navigation is improved. The experiment results show integrated navigation system based on SINS/GPS/TACAN can gain better location accuracy.
Keywords:integrated navigation  federated filter  SINS  GPS  TACAN
