Did you know that radio telescopes are synchronized down to the nanosecond (1/1,000,000,000 s) via the SURF Network? And that VU leverages the frequency signal provided by SURF to determine the weight of an electron?
Through the new SURF Time & Frequency network, the Dutch UTC time from VSL in Delft is distributed with extreme precision across the Netherlands via the SURF fiber optic network.
???? Curious to learn more? Last month, I recorded a podcast at SURF about Time & Frequency Transfer, where I explain what this technology is and how it is used.
