　　In GPS meteorology,the pressure and temperature parameters of GPS station are very important when obtaining accurate precipitable water vapor(PWV).However,there are few GPS stations equipped with co-located sensors for these meteorological parameters.In order to solve the problem,two methods,which is Parameter Conversion Method(PCM)and Layer Interpolation Method(LIM),were analysed and compared in this paper.
