【摘要】：国际天文联合会(IAU)在1991年和2000年分别通过了关于相对论天文参考系的重要决议。特别是2000年的决议,以两个互相等价的相对论N体多参考系理论:Brumberg-Kopeikin体系和Damour-Soffel-Xu体系为基础,构造了严格且自洽的一阶后牛顿(1PN)的局部参考系和全局参考系,并给出了相应的坐标变换规则。IAU2000决议发表后的10多年里,已经开始应用在一些高精度的天体测量数据处理模型中,但是其工程化应用还没有得到广泛实现,特别是目前为止我国没有将其应用到具体的天文观测或者空间探测计划中。因此有必要对IAU的相对论天文参考系理论做一个系统的解读。首先介绍了IAU在1991年给出的一个简单的相对论参考系决议;随后在第3章和第4章详细讨论了Brumberg-Kopeikin理论和Damour-Soffel-Xu体系;接着,详细给出了IAU2000年大会关于相对论参考系的决议内容;最后,讨论了IAU2000决议的工程化应用、近10多年来的理论发展以及对未来的展望。
[Abstract]:The International Astronomical Union (IAU) adopted important resolutions on relativistic astronomical reference systems in 1991 and 2000 respectively, especially in 2000, based on two equivalent relativistic N-body multireference systems: Brumberg-Kopeikin system and Damour-Soffel-Xu system. The local and global reference systems of strict and self-consistent first-order post-Newton 's 1PN) are constructed, and the corresponding coordinate transformation rules .IAU2000 are given for more than 10 years after the publication of the corresponding coordinate transformation rules. It has been applied to some high precision astrometric data processing models, but its engineering application has not been widely realized. In particular, China has not applied it to specific astronomical observation or space exploration plans so far. Therefore, it is necessary to make a systematic interpretation of IAU's theory of relativistic astronomical reference system. First of all, it is introduced that IAU gave. A simple relativistic reference system resolution; Then in chapter 3 and chapter 4, the theory of Brumberg-Kopeikin and the system of Damour-Soffel-Xu are discussed in detail. Then, the content of the resolution on relativistic reference system of IAU2000 annual conference is given in detail. Finally, the engineering application of IAU2000 resolution is discussed. The last 10 years of theoretical development and prospects for the future.
