NUTON: NPL's UTC Time Over Networks (pronounced Newton)

NUTON项目（NPL的UTC Over Networks）是一项可行性研究，将调查最合适的技术，这些技术可用于提供位于特丁顿的主要NPL设施、拟议的国家定时中心（NTC）枢纽和英国关键国家基础设施核心位置之间的时间传递机制。选定的时间传输技术将使NTC集线器与位于特丁顿的国家物理实验室控制的UTC时间同步，并允许NTC集线器随后使用选定的技术之一来同步最终用户应用程序。由于潜在的大量地理上不同的终端用户应用程序需要同步到UTC(NPL)，因此预计所需的时间传输技术将包括某种形式的无线低频广播系统。

The NUTON project (NPL's UTC Over Networks), is a Feasibility Study that will investigate the most suitable technologies which could be used to provide a time transfer mechanism between the main NPL facility at Teddington, the proposed National Timing Centre (NTC) hubs and core Critical National Infrastructure locations across the UK.The selected time transfer technologies will enable the NTC hubs to be synchronised to the UTC timescale controlled by NPL at Teddington, and will allow the NTC hubs to then use one of the selected technologies to synchronise end-user applications.Due to the potentially large number of geographically diverse end-user applications that need to be synchronised to UTC(NPL) it is envisaged that the time transfer technology required will include some form of wireless low frequency broadcast system.
