The United Kingdom’s National Positioning, Navigation and Timing (PNT) Office is considering changes to public use of the country’s legacy long-wave radio-wave time and frequency broadcast signal service, 60kHz MSF. The MSF broadcast, which provides UK ‘time’ traceable to the UK’s time scale generated by the National Physical Laboratory, is a terrestrial signal that can be received across much of the UK.
The NPNT is seeking evidence to better understand how the signal is used, its criticality, and potential future requirements, including all uses of the service, and has invited public input. It will also attempt to identify the benefits that users derive from the MSF signal, any unique capabilities it provides, and opportunities and barriers to wider adoption of the MSF signal.
The NPNT is seeking responses from anyone who currently uses or relies upon the MSF signal, including:
• operators of national infrastructure
• industrial and commercial users
• researchers and specialist users
• consumers
• individual users
This information will help to inform future policy and decisions relating to timing and frequency services in the United Kingdom.
The National Positioning, Navigation and Timing Office works to improve resilience and drive growth with responsibility for PNT policy, coordination and delivery. It was established in the Department for Science, Innovation and Technology as part of the announcement of the government’s Framework for Greater PNT Resilience and works across government to deliver the framework and drive the improvement of PNT resilience across the Critical National Infrastructure and the wider economy.
