Webinar – GNSS Timing Threats and Fallback Options – VIEW RECORDING

Webinar held 23 June 20221, 17:00 London, 12:00 New York

GNSS-based timing is ubiquitous and free, but at the same time exceptionally vulnerable to interference. The United Kingdom is in the first phases of implementing its National Timing Centre as part of a national timing infrastructure. It is also developing a national PNT strategy for which time will be a critical foundational element.

This webinar will feature some of the UK’s leading experts in timing technology and dissemination and guest Ms Karen Van Dyke of the U.S. Department of Transportation. They will discuss the nature of resilient terrestrial timing architectures and systems that can contribute to them.
