关于中星仪星表和等高仪星表

Transit Catalogue and Astrolabe Catalogue

对中星仪星表和等高仪星表的仪器与环境误差和它们的归算方法与测量精度作了分析、比较与讨论。指出,在中星仪和等高仪退出ERP服务和天体测量新技术开始实施后,中星仪和等高仪仍能在星表工作和参考系工作方面作出重要贡献。同时指出,天体测量新技术并不能完全取代地面经典天体测量,在今后一个相当长的时间内,地面经典天体测量仍有着坚强的生命力。

In this paper the transit catalogue and the astrolabe catalogue are discribed. All sorts of the errors in the star position determination by transit and astrolabe including the instrument errors and environment errors are analysed, indicating that the sourses and the reasons causing these errors are clear,and that many of them can be determined technically and theoretically at the present time. The methods of catalogue compilation are discussed,and results indicate that many of these errors can be eliminated by these methods,and that the important contributions of the transit catalogue and the astrolabe catalogue to the astrometry and to the fundametal reference system would be possible.When we fully use the merits of the methods,and make efforts in the investgation,determination and elimination of the various errors,the excellent transit and astrolabe catalogues will be made. They will give good contributions to the internal uniform of the fundamental reference system for a long period, though the new astrometry technigues have been used.
