Summary
The CLONETS-DS project aims to establish a pan-European time and frequency reference system as a European Research Infrastructure to serve the European science community. It is based on transmitting ultra precise time and frequency information via optical fiber.
The project builds on several joint European projects and its direct precursor project CLONETS. We now go far beyond previous efforts by designing a sustainable, pan-European, ultra-precise time-and-frequency reference-system available to the European research community. This Research Infrastructure considers user needs, designs the required architecture, engineering models and roadmaps, and develops a sustainability model for the future service, thus strengthening the European research area.
Optical atomic clocks, which are the source of the ultra-precise time and frequency signals, are reaching uncertainties of 18 digits after the comma. These signals could benefit geodesy in terms of better navigation systems. Making use of relativistic effects, they might help monitoring the Earth's gravity field and climate change - melting glaciers and rising sea level.
