The "NTOL -- NPL Time Over eLoran" project will aim to demonstrate the broadcast of the UK NPL managed national resilient time-base across the UK by using the eLoran transmitter based at Anthorn in Cumbria. NTOL will synchronise the Anthorn eLoran transmitter directly to the NPL time-base and demonstrate accurate UTC time transfer by deploying eLoran rece...

Highly accurate atomic clocks have a broad and expanding range of vital applications and are used in many aspects of our daily lives. One well-known example is the GPS navigation system which depends on sub-microsecond accurate timing to provide both position and timing information. This information is used in communications systems, telecoms, finance and...

Precision timing is key to all aspects of modern infrastructure, from the national grid, to telecommunications, to financial trading, through to global, national, and individual navigation systems. In the case of telecommunications, a suitable timing network for synchronisation is crucial. Optical atomic clocks, frequently referred to as "quantum clocks",...

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 tr...

Arqiva, the BBC and Chronos want to evaluate the use of the existing 198 kHz infrastructure, currently used for audio broadcasting of the BBC's Radio 4 Longwave service, to also disseminate time and frequency to low cost, fixed location receivers suitable for applications including Critical National Infrastructure. If the 198 kHz system can be modified to...

"There is clear evidence of Quantum innovation from two key publications -- The UK Blackett report published by the Government Office for Science on 'The Quantum Age: Technological Opportunities' and the EU Report 'Quantum Manifesto'. These both address the growing importance of quantum technology and in particular for the development of future atomic clo...

The need for smart devices to have a highly accurate self-awareness of their own location, and the location of other smart devices around is becoming increasingly important. Many devices rely on a singular location technology (typically GPS), which is one type of the wider eco system of Global Navigation Satellite Systems (GNSS). These systems, whilst bec...

Project FEMTO-2ND (say "femtosecond", which is a millionth of a billionth of a second!) is a key step in the UK’s 5-year programme to bring the remarkable new concepts of quantum physics out of research labs and into the everyday world. Chronos Technology, TMD Technologies and the University of Bath’s Engineering and Physics Departments have teamed up to ...

Broadcasters, telecoms, banks and many other industries rely on time, precise to billionths of a second, to synchronise their digital signals. This timing comes from GPS receivers like those that locate our satnavs and smart-phones. But the signals they pick up from the GPS satellites are exceptionally weak. They are occasionally disrupted by solar storms...

FEMTO-AAD will play a key role in the UK’s 5 year programme to bring remarkable new concepts in quantum physics out of research labs and into real-world applications. Chronos Technology, TMD Technologies and the University of Bath’s Electronics Engineering and Physics Departments have teamed up to research UK-based hollow core fibre (HCF) manufacturing, a...

GAUL will play a key role in helping Europe’s new Galileo satellite system deliver the ultra-precise timing that our future mobile phones and broadcast stations will demand. This GAUL – like Julius Caesar’s - is divided into three parts! First, it partners Galileo with the emerging technology of eLoran to bring timing to mobile phone sites and broadcastin...

FEMTO will play a key role in the UK’s 5 year programme to bring the remarkable new concepts of quantum physics out of research labs and into applications. Chronos Technology, TMD Technologies and the University of Bath’s Electronics Engineering and Physics Departments have teamed up to create key components of these systems. They plan to develop innovati...
