Abstract：The tropospheric delay is the main error for GNSS navigation and positioning.Along with the accuracy improved and deep research, the UNB3m,EGNOS,SHAO,etc. tropospheric models were proposed in recent years. Three IGS stations are used to analyzed the accuracy of these models. The results offer some valuable information for COMPASS navigation users.
