Neural Network Aided GPS/INS Integration for UAV Navigation
Traditional INS/GPS integrated system would degrade sharply when GPS outages, a new method is proposed in this paper, which is a NN(Neural Network) aided KF (Kalman Filter) integration method.The structure of the method was shown summarily, the NN and KF design flow was discussed briefly, test experimentations have been done to prove the availability of the proposed method. Primary test results have shown that the proposed method can reduce the navigation solution during GPS outages, by about 70%, in comparison with INS stand alone results in GPS outage of 60 seconds.
