Alon Stern explores new research on improving timing resilience at ITSF 2024

Presentation will explore advancing beyond the current parametric holdover standard for superior ePRTC accuracy and stability during GNSS failures

  • Speakers: Dr. Alon Stern, senior manager of technology at Oscilloquartz, Adtran
  • Topics: Pushing the limits of ePRTC – timing the future in the face of increasing GNSS vulnerabilities
  • When: Wednesday, November 6, 10 a.m. CET
  • Where: ITSF 2024, Barceló Sevilla Renacimiento, Seville, Spain https://itsf2024.executiveindustryevents.com/Event/

To ensure holdover periods provide adequate protection for PNT-dependent infrastructure, the latest G.8272.1 standard introduces the concept of parametric holdover. This guidance is meant to ensure improved continuity and precision in PNT networks when GNSS is compromised. It includes specifications of the performance level of enhanced primary reference time clocks (ePRTCs) when GNSS fails.

In this session, Alon Stern will argue that critical PNT networks require longer holdover periods than those specified by the G.8272.1 standard. He will discuss simulations that boost the performance of ePRTC solutions and explain how the research findings can be implemented in real-world PNT networks to achieve 100 nanoseconds of accuracy for up to 100 days.
