GPS卫星应用于天球参考系连接之初探

The preliminary study of the GPS Application in radio and optical reference system connection

随着配置有CCD的地面光学望远镜和空间望远镜观测精度的不断提高，以及其它空间大地测量技术（VLBI、LLR、SLR和GPS等）的发展，对天球参考系也提出了越来越高的要求。

Along with ceaseless advance of metrical precision for ground optical telescope with CCD and spacial telescope , as well as , other space geodesy technique 's ( VLBI , LLR , SLR and GPS ) development , the more and moe request to the CRS is put forward .

国际天球参考系的使用、观测精度的提高和方法的改善要求采用与地球轨道运动无关的运动赤道上的起算点，Guinot提出的非旋转原点可作为这样一种选择。

The adoption of the International Celestial Reference System and the changes of observational strategy call for the use of departure point on the moving equator independently from Earth 's orbital motion . A Nonrotating Origin ( NRO ), proposed by Guinot , is selected .
