摘　　要：全球导航卫星系统(GNSS)时空信息服务面临复杂场景的信号覆盖性难题,无法解决“无处不在”的泛在时空服务需求。为此,开展基于北斗卫星导航系统(BDS)信号的室内外无缝导航定位技术研究和系统研制,实现泛在空间定位服务非常必要。本文首先定义了“地上/室外定位+地下/室内定位+云上定位”的泛在空间定位体系概念,提出了泛在空间定位体系架构、信号信息架构、应用服务架构,给出了体系关键技术、应用服务类型、应用模式,构建了泛在空间定位试验网络,开展了针对典型场景的地上/室外定位、地下/室内定位和云上定位性能的初步示范验证、测试结果分析与服务能力评估。研究结果表明:以BDS为核心的泛在空间定位试验网络可提供泛在时空信息服务,能够将BDS导航定位服务从开阔空间全面拓展到半遮蔽及全遮蔽空间。The global navigation satellite system(GNSS)faces challenges in signal coverage in complex scenarios,which hinders the provision of ubiquitous spatiotemporal information services.To address the difficulty of continuous satellite navigation positioning services across all spaces,research and system development based on signals of BeiDou navigation satellite system(BDS)for seamless indoor-outdoor navigation positioning technology are being conducted.This is crucial for achieving ubiquitous spatial positioning services.This paper first defined the concept of a ubiquitous spatial positioning system as“ground/outdoor positioning+underground/indoor positioning+cloud-based positioning”.It proposed the architecture of the ubiquitous spatial positioning system,signal information architecture,and application service architecture.The paper discussed key technologies,types of application services,and application modes within this system.Furthermore,it established a ubiquitous spatial positioning experimental network and conducted preliminary demonstration verification and performance evaluation of ground/outdoor positioning,underground/indoor positioning,and cloud-based positioning in typical scenarios.Research findings indicated that the experimental network based on BeiDou could provide ubiquitous spatiotemporal information services,expanding BeiDou navigation positioning services from open spaces to semi-obstructed and fully obstructed spaces.
