地下空间导航定位现状与展望
Status and prospect of navigation and positioning in underground space
摘要
地下空间已成为我国构建国家综合定位、导航与授时(PNT)体系的关键领域之一.本文围绕地下空间,首先进行了基于导航场景的空间分类,并从信号可用性、场景结构等7 个方面系统总结了导航定位面临的挑战;然后从多源传感器融合、预设基站、先验匹配,以及μ子、量子等方面梳理了当前主要的技术和方法,并归纳了开源的地下空间多源传感器数据集;最后围绕前端感知、传感器和平台、集群协同和后端优化展望了未来的发展趋势.
The navigation and positioning in underground spaces have become one of the key areas for building a comprehensive positioning,navigation and timing(PNT)system.Focusing on underground space,the space classification based on navigation scenarios is conducted firstly,and the challenges faced by navigation and positioning are summarized systematically from seven aspects,including signal availability and scene structure.Secondly,the current main technologies and methods are sorted out in the aspects of multi-source sensor fusion,preset positioning base stations,prior matching,muon,and quantum and other technologies,and open-source multi-sensor datasets for underground space are also given.Finally,the future development trends are discussed in the aspects of front-end perception,sensors and platforms,cluster collaboration,and back-end optimization.
