Application of neural network aided Kalman filtering to SINS/GPS
To allow Micro-electro-mechanical System(MEMS)-based SINS/GPS integrated navigation systems to meet the accuracy requirements during GPS outages
a Radial Basis Function Neural Network (RBFNN) aided Adaptive Kalman Filtering (AKF) information fusion method was proposed.Firstly
the system structure consisting of dual modes of RBFNN training and prediction was designed.The RBFNN was trained while GPS signals were available and the inputs for AKF measurement updates were predicted during the GPS outages.Then
the mathematic models for RBFNN and AKF were built and the training strategy for RBFNN and the adaptive algorithm for AKF were designed.Finally
the performance of the proposed information fusion method was validated using real field test data.Test and experiment results show that the position precisions are better than 15 m and 90 m during GPS outages at 40 s and 100 s
respectively.The proposed information fusion method can effectively damp the divergence of the navigation error during GPS outages and can provide a low-cost
high-robustness
and medium-accuracy navigation scheme for small Unmanned Aerial Vehicles(UAVs)
guided bombs and land vehicles.
