Abstract

This paper presents a terrestrial networked positioning system that obtains a reliable time reference from a national time scale realization and distributes it in a prototype to six roadside base stations through a fiber-optic Gigabit Ethernet network. Wireless wideband signals are transmitted by the base stations, thereby enabling positioning by a mobile receiver with an accuracy of one decimeter in a multipath urban environment. The scalability and compatibility of this sys-tem with existing telecommunication-network technologies paves the way for wide-area global navigation satellite system-independent back-up systems for timing and positioning with improved coverage and performance. The results presented in this paper are based on research carried out within the scope of a project funded by the Dutch Research Council (NWO, project 13970).

通过可扩展的光无线网络在城市环境中的分米定位

本文提出了一种地面网络化定位系统，该系统从国家时间尺度实现中获得可靠的时间参考，并以原型机的形式通过光纤千兆以太网分发给六个路边基站。无线宽带信号由基站传输，从而使移动接收器能够在多径城市环境中以一分米的精度进行定位。该系统的可扩展性和与现有电信网络技术的兼容性为广域全球导航卫星系统独立的定时和定位备用系统铺平了道路，从而提高了覆盖范围和性能。本文中提出的结果是基于荷兰研究理事会(NWO，项目13970)资助的一个项目范围内进行的研究。

期刊介绍： NAVIGATION is a quarterly journal published by The Institute of Navigation. The journal publishes original, peer-reviewed articles on all areas related to the science, engineering and art of Positioning, Navigation and Timing (PNT) covering land (including indoor use), sea, air and space applications. PNT technologies of interest encompass navigation satellite systems (both global and regional), inertial navigation, electro-optical systems including LiDAR and imaging sensors, and radio-frequency ranging and timing systems, including those using signals of opportunity from communication systems and other non-traditional PNT sources. Articles about PNT algorithms and methods, such as for error characterization and mitigation, integrity analysis, PNT signal processing and multi-sensor integration, are welcome. The journal also accepts articles on non-traditional applications of PNT systems, including remote sensing of the Earth’s surface or atmosphere, as well as selected historical and survey articles.
