Fiber-Optic Frequency and Time Distribution for Precision Timing and Synchronization in ESA’s ESTRACK Network
Year: 2026
Type: conference-paper
Abstract: High-performance frequency and time distribution is a fundamental requirement for coherent radio-frequency systems, including radio observatories, space tracking networks, and other distributed ground segments [1].Preserving the spectral purity and long-term stability of ultra-stable clock references during distribution is critical, as any excess phase noise or phase drift directly limits achievable coherence.Here, we present the architecture and operational performance validation of ESA's second-generation Frequency and Timing (F&T) system [2], developed to deliver ultra-stable frequency and time references across distributed ground station infrastructures using actively stabilized fiber-optic links.
