Abstract：The interpolation methods about the GPS RTK networks are firstly described,then from the GPS observations in GPS RTK network,the relations of doubledifferenced inonospheric delay with the baseline length and time are analyzed and compared with each other.The results show that the best interpolation method is LIM,its accuracy is higher than 3cm if the baselines are less than 100 km
