- With MiFID II due to be in place within two years, NPL and ICE have carried out a proof-of-concept to assess the NPLTime® service for its suitability for the impending regulations.
- NPL is part of the UK National Quantum Technologies programme that has launched its strategy.
- NPL's work on atomic timekeeping, and its use in the financial sector, feature in an article in The Independent.
- NMO has published the findings of a public dialogue on the future of leap seconds which NPL contributed to.
- NPL's Caesium fountain atomic clock and NPLTime are featured in an article on the BBC Future's website.
The Time & Frequency Group is responsible for operating the national time scale UTC(NPL) and disseminating time throughout the UK. Our caesium fountain primary frequency standard measures the SI second at the highest accuracy, and we contribute to the generation of the world's reference time scale UTC. We also maintain and disseminate another of the seven base SI units: the metre.
We carry out a broad programme of research in time and frequency metrology. A major activity is the development and characterisation of a new generation of optical atomic clocks based on laser-cooled trapped ions and atoms, which may lead to a future redefinition of the SI second. Potential applications of these clocks range from improved satellite navigation systems to sensitive tests of fundamental physical theories.
Other areas of current research include the development of compact and user-friendly frequency standards for industrial applications and unique algorithms for processing clock data to generate the most stable reference time scales achievable.
