摘　　要：导航技术对人类深入探索并开发地月空间具有重要意义。地基测控等传统导航技术在为地月空间航天器提供服务方面存在诸多挑战,如信号传输时延大、导航信号弱及观测几何条件差等因素导致导航精度和实时性差等问题,难以满足未来复杂的深空任务需求,而星间链路等天基导航技术为解决该问题提供了新的思路。在梳理地月空间导航特点与需求的基础上,重点讨论了天基导航技术的现状和特点,并展望了未来的发展方向,包括硬件、算法和新的导航体系等,为未来地月空间导航技术的发展提供了有益借鉴。Navigation technology is critical to humanity s advanced exploration and development of cislunar space.Traditional navigation methods,such as ground-based tracking and control,face significant challenges in supporting cislunar spacecraft operations.Issues such as high signal transmission delay,weak navigation signals,and poor observation geometry reduce both navigation accuracy and real-time performance,making it difficult to meet the requirements of complex deep space missions.Space-based navigation techniques,including inter-satellite links,offer new approaches to overcome these limitations.Based on the classification of the characteristics and requirements of cislunar space navigation,the current status and features of space-based navigation technology are discussed.Future development directions,including advances in hardware,algorithms,and novel navigation architectures,are also projected,providing valuable insights for the development of cislunar space navigation technology.
