In order to put the SDCORS datum station coordinates into the ITRF2008 coordinates frame and meet the requirements of the CORS station network's construction.This paaper uses the GAMIT/GLOBK software and take the effection of earth tide,ocean tide,atmospheric tide and polar tide into consideration to process the observation data of the SDCORS in 2012.We get the millimeter level accuracy of the coordinates and velocities of the SDCORS datum stations,and analysis the changing characteristics of these stations.Finally,we built a regional dynamic coordinates reference frame which is applied in Shandong province.
