Task: MATLAB simulation of GPS/INS integrated navigation
Mission requirements: assume that the initial state, the normal work of the GPS and INS, after filtering, using BP neural network for GPS and INS signals output training, after a period of time the GPS signal loss, using the neural network output signals as predicted, the INS error correction signal,
Task goal: output before and after filtering speed, position error contrast figure, confirmed that this method is effective improve the navigation precision, if at all possible to introduce a new algorithm to improve neural network,
