In the U.S., Executive Order 13905( Federal Register : Strengthening National Resilience Through Responsible Use of Positioning, Navigation, and Timing Services) signed 02-12-2020, ordered several federal agencies to conduct vulnerability assessments related to critical infrastructure. I'm looking for qualified opinions / research on the potential for degradation or loss of access to GPS / GNSS to potentially impact critical infrastructure at hydro-electric dams.
Well, 'Yes'. And not just the obvious spatial difficulties, it is the reliance on timing signals. The epicenter is NIST: Overview at https://www.nist.gov/news-events/news/2021/02/nist-finalizes-cybersecurity-guidance-positioning-navigation-and-timing and from there are other domain specific documents like https://www.nist.gov/news-events/news/2019/08/situational-awareness-electric-utilities-nist-publishes-cybersecurity
Behind all these is usually quite a paper trail of conference presentations, meeting transcripts, etc. from stakeholders providing input, usually referenced in the bibliographies of the documents. The exceptions are, obviously, classified content with specifics on actual incidents and unresolved current vulnerabilities.
Yes Michael John Patrick timing signals of GPS/GNSS can be used in the infrastructure at hydro-electric dams.
