利用不同版本的数值历表,对我国正在进行的探月工程以及后续的金星、火星和木星等深空探测中的导航问题进行分析和讨论。对DE405、DE421和DE430的动力学模型及其使用的观测数据进行了分析比较,考察了历表的精度和稳定性。并根据DE430历表简单讨论了木星在我国深空探测站的可视问题,为以后深空导航提供参考。简单讨论了中科院国家天文台行星无线电研究团组基于月球无线电测距(LRR)发展我国自己的历表以及开展基于月球深空导航计划的可行性。
Using different versions of the numerical calendar, the ongoing lunar exploration project in China and follow-up navigation in deep space exploration such as Venus, Mars and Jupiter are analyzed and discussed. The kinetic models of DE405, DE421 and DE430 and their observed data are analyzed and compared, and the precision and stability of the calendar are investigated. According to the calendar of DE430, the visual problems of Jupiter in China’s deep space exploration station are simply discussed, providing a reference for future deep space navigation. This paper briefly discusses the feasibility of developing our own calendar based on moon radio range finding (LRR) and carrying out lunar deep space navigation based on the lunar radio spacecraft research team of the National Astronomical Observatories.
