Last Mile Delivery of non-GNSS resilient time, frequency and synchronisation (TFS)

全球导航卫星系统的使用在我们的社会中根深蒂固，经常被用来获得精确的时间或定位数据，以运行我们关键的国家基础设施的关键要素。我们对它的依赖不能被低估。非GNSS弹性时间、频率和同步的最后一英里交付(TFS)项目承认系统的脆弱性，并探索如何使其具有更强的弹性。时间传播的弹性对于应对政府设定的关键重大挑战和加快其数字议程以改善公民体验至关重要，所有这些都将需要灵活、可扩展和弹性的基础设施来拥抱云计算和认知技术。克兰菲尔德大学和霍普特洛夫大学合作，探索如何在连接的最后一英里嵌入对GNSS故障的弹性和时间传播保证，并最终使英国能够在互联自治需求大幅增加的情况下向世界各地出口服务。

GNSS use is deeply embedded in our society, often used to obtain precise timing or positioning data for the operation of key elements of our critical national infrastructures. Our dependency on it cannot be under-estimated. The Last Mile Delivery of non-GNSS resilient time, frequency and synchronisation (TFS) project acknowledges the vulnerabilities of the system and explores the ways of how it can be made more resilient.Resilience in time dissemination is essential to meet the key grand challenges set by government and accelerate its digital agenda to improve the citizens' experience, all of which will require flexible, scalable and resilient infrastructure to embrace cloud computing and cognitive technologies.Spirent, Cranfield University and Hoptroff have partnered together to explore how to embed resilience and assurance of time dissemination to GNSS failures into the last mile of connectivity and ultimately enable the UK to export services around the world as demands in connected autonomy greatly increase post covid.
