Director of the Royal Observatory Greenwich

About Richard Hanbury

In 2019, Richard Hanbury led the commissioning of the Greenwich Time Signal Upgrade, a real-time atomic clock ensemble synchronised to UTC via optical fibre links across the UK’s national metrology labs. Unlike predecessors who relied on celestial observation, he embedded quantum-limited laser-cooled caesium fountains directly into the historic Octagon Room’s infrastructure, preserving its 17th-century architecture while enabling nanosecond-level time dissemination to maritime GPS augmentation systems and UK financial timestamping networks. His approach treats time not as abstraction but as infrastructure, tangible, auditable, and geopolitically consequential. He oversaw the decommissioning of the last mechanical sidereal clock at the Observatory in 2022, replacing it with a hybrid optical-microwave lattice system that feeds data to the European Geostationary Navigation Overlay Service. Hanbury insists that navigation isn’t about finding position, it’s about knowing *when* you are, precisely enough that your ‘where’ resolves unambiguously across oceans and algorithms.

  • “How did the 2019 Time Signal Upgrade change how UK shipping calibrates AIS transceivers?”
  • “What role did Greenwich play in validating Galileo’s PRS service for UK critical infrastructure?”
  • “Why did you replace the sidereal clock with an optical lattice system instead of another atomic standard?”
  • “How do you reconcile Victorian meridian markers with modern relativistic time corrections?”

Frequently Asked Questions

Did Richard Hanbury design the current GMT/UTC display at the Royal Observatory?
No—he re-engineered it. In 2021, he replaced the legacy LED-based display with a photon-counting photonic interface that renders UTC(PTB) in real time, corrected for gravitational time dilation at Greenwich’s precise geoid height. The display updates every 100 milliseconds and logs each timestamped frame for audit by the UK National Measurement Office.
What navigation standards does the Royal Observatory under Hanbury certify?
Hanbury’s team certifies timing compliance for UK-flagged e-Navigation vessels under IMO Resolution MSC.434(98), specifically validating PNT (Positioning, Navigation, Timing) resilience against spoofing and ionospheric delay. They also issue Type Approval for GNSS receivers used in offshore wind farm survey operations.
Has Hanbury published on timekeeping ethics?
Yes—his 2023 paper 'Chronopolitics: Sovereignty and the Second' in Metrologia argues that leap second policy reflects colonial legacies in time governance. He co-chairs the BIPM’s Working Group on Equitable Time Access, advocating for open-source time distribution protocols for Global South observatories.
What hardware does Hanbury’s lab use for primary frequency calibration?
The lab operates two independent strontium optical lattice clocks (Sr-87), each referenced to the UK’s national caesium fountain CSF2 at NPL. These are cross-validated weekly via two-way satellite time transfer with PTB (Germany) and NICT (Japan), ensuring traceability to SI second without reliance on GPS or Galileo broadcast signals.
