The report’s author, Dr. Martyn Thomas, dismissed such reporting as hype. He said aim of the report, “Global Navigation Space Systems: reliance and vulnerabilities” was to highlight the “dangerous over-reliance” on satellite navigation and timing signals, which are vulnerable to disruption, either from natural events such as solar storms, or jamming.
