Error correction of troposphere delay for long range network RTK

ZHU Hui-zhong;XU Ai-gong;GAO Meng;YUAN Hong-chao;School of Geomatics,Liaoning Technical University;Science and Technology on Aerospace Flight Dynamics Laboratory;  
Aiming at the situation that long range network RTK reduces the correlation of regional observation error and has influence on the interpolation calculation and correction of troposphere delay error,aproved method which was used to calculate and correct troposphere delay was proposed.Firstly,the zenith troposphere delays of base stations were calculated by the fixed integer ambiguities of base station networks.Then the zenith troposphere delay of rover was calculated by the interpolation model.And the troposphere delay calculating and correcting of each satellite on rover could be realized.The test results by the data of long range CORS indicated that the satisfactory error correction effect and positioning results on rover with long range networks RTK could be obtained by the proved algorithm.
