Chronos at ITSF 2-5 November 2026, Geneva, Switzerland
We’re participating in the International Timing & Sync Forum 2-5 November 2026 in Geneva. Join us at the world’s largest timing and sync event where the global timing community meets for three days packed with critical discussion, unrivalled industry networking, world-class speakers and a cutting edge exhibition .
We will showcase the latest time and synchronisation solutions and our team will be available to discuss timing challenges in Telecoms, Finance, Broadcast, Transport, Utilities, IoT and Defence as well as many other existing and emerging vertical markets for which precise timing and sync is becoming increasingly important.
In addition, Tony Flavin and Chris Farrow will present:
Correlating UTC Transfer Accuracy Variations with LEO Broadband Constellation Orbital Dynamics
As Low Earth Orbit (LEO) communication constellations become a critical component of global digital infrastructure, understanding their capacity for precise time synchronisation is essential. While LEO broadband networks offer a low-latency alternative to terrestrial backbones, the highly dynamic nature of their geometry — characterised by rapid satellite motion and frequent handovers — challenges standard synchronisation protocols.
This talk builds upon previous measurements of Network Time Protocol (NTP) performance over commercial LEO links and introduces a predictive network delay model based on real-time Two-Line Element (TLE) orbital data and known terrestrial gateway locations. To validate this model, we utilise high-resolution NTP telemetry with granularity that allows the capture of transient jitter and offset shifts associated with the constellation’s deterministic 15-second reconfiguration cycle. A correlation analysis is performed between modelled propagation delays — accounting for slant range and relativistic effects — and empirical NTP offsets measured over the United Kingdom.
Our conclusions demonstrate how constellation-aware modelling can differentiate between network congestion and predictable orbital handovers, ultimately defining the boundaries of LEO networks as a viable source for sub-millisecond primary or backup synchronisation in critical infrastructure.
We’re looking forward to meeting you and in the meantime more information about our sync and timing solutions is available here.
