| Abstract: | The GPS vapor detection,which is based on the signal delay caused by the refractivity when the GPS signals pass through the atmosphere,is a precipitable water vapor（PWV） forecast technique with a bright prospect.This paper discusses the principle,method and data-processing process by GAMIT software.With the PWV calculated by the sounding data,the accuracy of GPS PW derived from HHCORS observation data was analyzed.The results showed that the GPS precipitable water vapor has a high precision. |
