项目摘要

High precision (c.100nsec) electronic clocks are widely employed to synchronize distributed data/communication networks in many sectors (e.g. defence/security, telecommunications, financial, and utilities). These clocks are essential network components and represent a significant global market estimated at c.US$230m pa. The majority of these clocks utilise signals transmitted from Global Navigation Satellite Systems (GNSS). Considerable concern, at governmental level, is developing over the vulnerability of these signals to equipment failure or 'attack' and the resultant disruption, which would ensue from alternative provisions (e.g. Galileo) currently being developed. Significantly, there has been renewed interest and investment in using ground based technologies to 'back up' high precision timing provision, the principle one being the eLORAN system (enhanced LORAN) which is an upgrade of the well established LORAN system. The University of Bath, under STFC funded research into lightning research, has demonstrated the possibility to build a high precision clock, based on the use of eLORAN signals, comparable in performance to GNSS based clocks (Füllekrug, Meas. Sci. Tech., 21, 015901, 2010, and Füllekrug et al., Geophys. Res. Lett., 36(L06104), 2009). It is believed that this technology has the commercial potential for integration into current precision electronic clock products to act as either a 'back up' or as a primary source when GNSS signals are weak or non-existent (see attached letters of support from Motorola and the National Physical Laboratory). The proposed STFC Follow-on Fund project will explore in great detail the market (size, competition) and the route to market options. On the technical side a 'proof of concept' unit will be developed (with a focus on performance and compactness within a target 'production cost'), and supply chain partners and the potential to IP protection will be investigated.

高精度（c.100nsec）电子时钟被广泛用于同步许多部门（例如国防/安全，电信，金融和公用事业）中的分布式数据/通信网络。这些时钟是必不可少的网络组件，代表了一个重要的全球市场，估计每年约2.3亿美元。这些时钟中的大多数利用从全球导航卫星系统（GNSS）传输的信号。政府一级对这些信号易受设备故障或“攻击”以及由此产生的中断的脆弱性正在产生相当大的关注，这将导致目前正在开发的替代规定（例如伽利略）。值得注意的是，人们重新对使用地面技术“支持”高精度授时产生了兴趣和投资，其中一个主要的技术是eLORAN系统（增强型LORAN），它是对已建立的LORAN系统的升级。巴斯大学在STFC资助的闪电研究的基础上，已经证明了建立一个高精度时钟的可能性，该时钟基于eLORAN信号的使用，在性能上与基于GNSS的时钟相当（Füllekrug，Meas. Sci.技术人员：21，015901，2010和Füllekrug等人，地球物理学家。保留信函：36（L06104），2009）。据认为，这项技术具有商业潜力，可纳入目前的精密电子钟产品，在全球导航卫星系统信号微弱或不存在时作为“备用”或主要信号源（见所附摩托罗拉和国家物理实验室的支持信）。拟议的STFC后续基金项目将详细探讨市场（规模、竞争）和通往市场的途径。在技术方面，将开发一个“概念验证”单元（重点关注目标“生产成本”内的性能和紧凑性），并将调查供应链合作伙伴和知识产权保护的潜力。
