地月空间多源数据融合导航定位技术综述:进展与启示OA

The rapid growth in the number of cislunar spacecraft imposes stringent requirements for high-precision and highly autonomous navigation systems,while traditional ground-based navigation exhibits inherent limitations.To address these challenges,this work systematically reviews and compares the fundamental principles and cislunar adaptability of major navigation technologies,including ground-based tracking,celestial navigation,and inertial navigation.Special focus is placed on advanced space-based approaches such as weak GNSS signal enhancement,orbit determination via inter-satellite links,and linked autonomous interplanetary satellite orbit navigation(LiAISON).The study demonstrates that space-based navigation offers significant advantages in overcoming challenges related to spatio-temporal reference inconsistency,signal attenuation,and resource allocation,with multi-source data fusion serving as the core pathway to high-performance navigation.Promoting the synergistic development of space-based navigation and multi-source fusion technology is crucial for constructing a highly reliable navigation architecture capable of meeting the demands of future cislunar missions.
