摘要

To satisfy the high-reliable navigation demand in the complex environments for the tactical missile, a new multi-sensor integrated navigation technique was studied. First, a integrated SINS/GPS/EC navigation method based on the self-adaptive federated Kalman filter is proposed, and a new multi-sensor integrated navigation model was established. Then, according to the theory of self-adaptive federated filter, two sub-filters model, namely, SINS/GPS filter and SINS/EC filter model, were built and analyzed. Finally, simulation experiments are made. Comparing with traditional method, the simulation results show that the proposed method can reduce the computation burden and improve the stability and fault tolerance with no less of accuracy.
