| Abstract: | Taking the results of Haizhong first leveling control network of Jintang Bridge as an example,this paper studied the accuracy of GPS height abnormal fitting model.It compared between the normal height calculated by plane fitting model and polynomial surface fitting model,and the results of fourth order leveling.It got some beneficial conclusions and could guide the practical application of GPS. |
