| Abstract: | Based on the research results of GPS leveling elevation fitting, this paper studies the methods on GPS elevation abnormal fitting based on artificial neural network. By using practical data, it studies the BP(Back Propatation)network model, Radial Basis Function Neural Network model, and through comparisons and analysis of these fitting models, gives the accuracy assessment on the diverse fitting models. |
