Resilient Timing for Critical National Infrastructure

Critical infrastructure requires precise timing to operate. This reliance makes the infrastructure vulnerable to disruptions in timing that can be either intentional or unintentional. Intentional disruptions can be caused by GNSS jamming or spoofing or network attacks.. Unintentional disruptions are usually caused by equipment failures or acts of nature.

Back in April 2022, Alliance for Telecommunications Industry Solutions (ATIS) hosted a webinar on this topic, a precursor to the Annual Workshop on Synchronization and Timing Systems (WSTS). The webinar featured top industry experts delivering insight into the latest techniques for adding resilience and robustness to timing infrastructure. It covered the most critical topics in timing resilience, including:

  • Redundancy
  • Holdover
  • Management
  • Monitoring
  • Alternative reference time sources

Examples address networks used for critical industry applications such as:

  • Power grids
  • Telecommunications
  • Finance systems
  • Broadcast/media

The video of the webinar as follows:

Couple of presentations on GNSS and LCS

I came across couple of presentations from International Conference on Localization and GNSS, held in Tampere, Finland, June 29-30, 2011

This first presentation by Lauri Wirola of Nokia gives good summary of standardized positioning technologies in use today. It also lists the difference between control plane and user plane positioning. The 3GPP based positioning from Rel 5 to Rel 8 has been listed. Overall a very interesting presentation.

The second presentation by Ignacio Fernández Hernández of the European Commission, gives an overview of the EU satnav programmes (Galileo, EGNOS) and current R&D status; Present some numbers and findings of the overall GNSS R&D panorama in EU and abroad; Present some trends and challenges in location technologies for the following years. Another interesting presentation I think.
