Abstract The stations constrained on international terrestrial reference frame (ITRF) are usually chosen with some random and uncertainties, which directly affects the precision and reliability of ITRF. A system method to select stations on the rigid plate was summarized.Firstly, analysing the quality of data at each station,the second step is rigorous selection of the stations 7 parameters transformation. The third step is supervision clustering to eliminate some stations that is largely affected by local diastrophism and finally,we make stations wellproportioned spacial distribution. With by using the method, IGS frame station can be chosen in GNSS data processing to establish high precision terrestrial reference frame.
