VLBI在建立准惯性参考系上的作用

The Role of VLBI in the Construction of the Quasi-inertia Reference System

本文对以下问题作了论述:现用基本参考系的局限性,VLBI在建立准惯性参考系上的作用,射电源星表的进展,射电源星表误差来源的分析和考虑,综合射电源星表建立的需要,光学、射电和空间天体测量星表联系的必要性,用中国VLBI网进行天球参考系工作的一些初步考虑。

In this paper the following problems are discussed, namely the limitations of the current fundamental reference system, the role of VLBI in the construction of a quasi-inertia reference system, the progress of the catalogues of radio sources in the last few years, the analysis and considerations on the error sources of the radio sources catalogues, the necessity for the construction of a synthesis catalogue, the requirment of the link between the optical catalogues, radio catalogues and space astrometric catalogue, and some preliminary considerations of the research on the celestial reference frame with the Chinese VLBI network.
