地球参考系

评述了地球参考系在近十几年来的研究进展；

Secondly , the recent progress of the CTRS research is reviewed .

并结合90年代对地球参考系的毫米级要求，讨论了目前存在的问题和可能的改进设想。

Finally , we discuss the problems and possible improvements for CTRS with millimeter accuracy in the1990 's.

随着空间大地测量技术（VLBI、LLR、SLR和GPS等）的发展，对地球参考系也提出了越来越高的要求。

With advance of metrical precision for space geodesy techniques ( such as VLBI , LLR , SLR and GPS ), more and more request to the TRS is put forward .

上海天文台的佘山VLBI、SLR和GPS站是国际上用以建立和维持地球参考系进行全球动力学研究的基准台站，联合应用这些空间测量，需要知道这三个站心间的三维相对位置。

The VLBI , SLR and GPS stations of Shanghai Observatory are international fiducial stations used for establishing and maintaining global reference frames and for studying global geodynamics . The relative positions of these three stations are necessary in the combination use of their different techniques .
