Interpolation algorithm of GPS tropospheric delay based on GA-BP

YIN Weisong;TAO Tingye;DENG Qingjun;GAO Fei;Hefei University of Technology;Anhui Jiyuan Software Co.Ltd.;Anhui Electric Power Design Institute;  
In order to improve the interpolation accuracy of tropospheric delay,the paper proposed an interpolation method of regional GPS tropospheric delay based on GA and BP neural network by using the static data of 10 AHDLCORS stations as the training data,and the 8remaining CORS stations as test data:the GA was used to optimize the weights and threshold value of BP neural network with the input parameters of the latitude,longitude and altitude.Result showed that the GA-BP model would be an efficient method for tropospheric delay forecasting with high precision.
