“PNT is still too often treated as a navigation issue. That is too narrow,” says Andy Proctor, Vice President of the Royal Institute of Navigation, Chair of the PNT Advisory Group, and a member of GPS World’s Editorial Advisory Board. “Satellite-derived PNT does not only help ships, aircraft, and vehicles find their way, it also provides the precise timing and synchronization that supports telecommunications, financial transactions, data centers, electricity monitoring, digital trust services, logistics and emergency response,” Mr. Proctor wrote in an essay on the website of the U.K. National Preparedness Commission. “The preparedness question is therefore not whether the UK can manage without satellite navigation, but whether essential services remain within tolerance when trusted time, position, or navigation is lost or corrupted.”
“Preparedness is most valuable when it improves resilience across many shocks, rather than examining hazards in isolation. PNT fits that test exactly because the same underlying dependency can be disrupted by technical failure, jamming, spoofing, cyber-enabled interference or severe space weather.”
