Abstract

The Resilient Enhanced Time Scale Infrastructure (RETSI) is an atomic clock network distributed geographically in secure locations, that is being developed as part of work in the National Timing Centre programme. It will become the source of UTC(NPL), the physical realisation of Coordinated Universal Time (UTC) maintained by the National Physical Laboratory (NPL) in the United Kingdom (UK). Dissemination points called User Access Nodes will link to RETSI via Orchestration Nodes, allowing users to access time and / or frequency references traceable to UTC(NPL). This will help to improve security and resilience in national time and frequency generation and distribution, enabling the UK to reduce its dependence on timing signals from Global Navigation Satellite Systems.
