对近年来精度高、应用较多的国际地球参考架ITRF2005做了简单概述，指出了ITRF2000与ITRF2005之间在解的生成、基准的定义和实现等方面的不同。此外， ITRF2005除了包含作为参考框架体现的站点坐标和速率之外，还包含一起参与联合处理的地球定向参数：极移、极移速率、日长、UT1的时间序列[1]。重点阐明ITRF2005的实现的基本情况及其相对于ITRF2000所作改进的理由和合理性。

This paper summarized ITRF 2005 which is of high accuracy and wildly used these years, and pointed the difference be-tween ITRF 2002 and ITRF 2005 in formation mechanism of solution, definition of benchmark, implementation and other aspects. ITRF 2005 not only includes the position coordinate and rate expressed in the reference frame, but also includes jointly processed earth orientation parameters, which is, polar motion, rate of polar motion, day length, and time series of UT1.Moreover, the general infor-mation to accomplish ITRF2005 and reasons and reasonability of improvement compared to ITRF2000 is also emphasized.
