摘　　要：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。The role of orbit measurement data of deep space probes in development of planetary and lunar numerical ephemerides is described to meet requirements of deep space navigation systems for solar system body ephemerides following analysis of the evolution of the quantity and accuracy of popular numerical ephemerides in the world.A proposal is presented for independent development of numerical ephemerides by China using tracking data of deep space probes based on the distribution,types of measurements and accuracy of China＇s deep space TTC network and requirements of deep space navigation in the future.Key technologies related to the proposal are summarized for reference in independent development of numerical ephemerides of solar system bodies by China.
