摘要
为了将SDCORS基准站的坐标纳入到ITRF2008坐标框架中,满足CORS基准站网的建设要求。本文使用GAMIT/GLOBK精密GPS数据处理软件,并考虑对流层延迟和地球固体潮、海潮、大气潮和极潮等的影响,对78个SDCORS基准站2012年全年的观测数据进行解算。最终,得到SDCORS基准站在ITRF2008坐标框架下毫米级精度的三维坐标和速度,并对该年度SDCORS基准站的站坐标变化特征进行了分析,建立了适用于山东省地区的区域动态坐标参考框架。
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.
