GNSS signals are increasingly vulnerable to jamming, spoofing and disruption, putting critical infrastructure, transportation and national security at risk. To stay ahead of these threats, organizations must rethink how they generate, secure and distribute time. That means embracing layered resilience, regulatory alignment and robust holdover to ensure operations continue even when satellite signals fail.
In this session, Bartek Kropiewnicki will explore how to build timing architectures that are resilient, redundant and ready for a GNSS-denied environment. He’ll outline the technologies that underpin next-generation solutions, from multi-source timing and PTP distribution to ePRTC systems with integrated cesium clocks, empowering operators to navigate their next GNSS crisis with confidence. The discussion will also touch on broader innovations shaping resilient timing, from authentication with Galileo OSNMA to sub-nanosecond distribution via White Rabbit and emerging LEO-based timing services – highlighting how layered approaches strengthen assurance across networks.
