| Abstract: | The role of data quality assessment on the third order GPS geodetic network is introduced at first. The methods and index of data quality assessment are present then. Using TEQC, 48 stations GPS observation data in qinghai area of the third order GPS geodetic network are assessed, and the index are analyzed statistically combined with baseline resolution. |
