10. Time Enables Critical Infrastructures
TRENDS:
Accuracy
MiFID II, Phase accuracy for wireless communications and power grid, ePRC/ePRTC standards in telecom
Resiliency
GNSS Vulnerability is not new, however nefarious jamming and spoofing is
Gov entities and critical infrastructure are investigating ways to operate in GPS denied environments through cesium reference clocks and autonomous timescales
Security
Analogous to virus/phishing/DoS threats, GNSS spoof detection and mitigation requires multilayer approach to detect, protect and mitigate.
