| Abstract: | The conversion of GPS height is the key in GPS applications.The functions of BP neural network in toolbox of MATLAB and the applying steps were introduced.Three schemes were designed to convert GPS height.The MATLAB program based on BP neural network method was provided.Through calculating the true measuring data,the result shows that neural network method can obtain higher accuracy than quadric polynomial fitting method if adopting appropriate training function and fine network structure. |
