It is difficult to do dead reckon(DR) position'zero update' for vehicle GPS/DR integrated navigation system in case of GPS signal blockage,a new DR position algorithm is put forward based on the back-propagation(BP) neural network.Firstly,DR position data is de-noised with stationary wavelet transformation(SWT) model square root soft-threshold de-noising algorithm,and the vehicle precise position data is acquired with extended Kalman filter(EKF) data fusion algorithm based on SWT during the presence of GPS ...
