针对深空探测任务导航系统对太阳系天体历表的需求,通过分析目前国际上已有数值历表所采用的测量数据类型、数量和精度等方面的变化和规律,明确了深空探测器测轨数据对研制太阳系天体数值历表具有重要作用。根据我国深空测控网的布局、测量数据类型和精度,结合我国未来深空探测任务的需求,提出将我国深空探测器跟踪测量数据用于自主研制数值历表的思路,总结了自主研制天体历表需要解决的关键技术问题,为我国太阳系天体数值历表的自主研制提供技术参考。
In view of the demand of solar system celestial body calendar for deep space exploration mission navigation system, by analyzing the change and regularity of measurement data type, quantity and accuracy currently used in numerical almanac in the world, The data plays an important role in the development of solar system celestial body numerical calendar. According to the layout of China’s deep space monitoring and control network, the type and precision of measurement data and the demand of future deep space exploration mission in China, this paper puts forward the idea of using China’s deep space probe tracking measurement data for independent development of numerical calendar. The key technical issues to be solved in the calendar are to provide a technical reference for the independent research on the numerical calendar of celestial bodies in China’s solar system.
