摘　　要：主要介绍了IERS2003规范中国际地球参考系(ITRS)到地球质心天球参考系(GCRS)的转换过程,以及与IAU2000决议一致的常规转换公式,并详细分析了以IERS计算程序为工具、“基于CEO”[注]和“基于春分点”的ITRS向GCRS转换的两种等价方案和相应的三种应用方法,最后对新坐标系转换模型的应用进行了探讨。This paper introduces the processes of coordinate transformation between the International Terrestrial Reference System and Geocentric Celestial Reference Systems, and gives the transformation expressions consistent with the IAU 2000 resolutions in IERS Convention 2003.The following sections give the details of two equivalent ways, which called respectively 'CEObased' and 'equinoxbased' transformation, and three methods application, IERS routines for transformations from ITRS to GCRS. Finally, the applications of new developments are discussed.
