GPS-Independent Timing Solutions for US Critical Infrastructure
Secure Your Operations Against GNSS Vulnerabilities
Executive Order 13905 recognises the increase in cybersecurity threats. America's infrastructure cannot rely solely on GPS signals that are vulnerable to jamming, spoofing, and cyberattacks.
Hoptroff delivers proven GPS-independent timing solutions that protect your worldwide operations whilst ensuring regulatory compliance.
Why GPS Independence Matters
GNSS vulnerabilities are increasingly recognised as critical risks:
🛡 Timing data is emerging as a target for cybersecurity threats
🛡 GNSS signals are vulnerable to jamming and spoofing attacks
🛡 Essential infrastructure operators need to improve resilience
🛡 Modern digital infrastructure requires reliable and accurate timing for continuous operations
Executive Order 13905 mandates GPS-independent solutions to:
✅ Protect critical infrastructure from timing-based attacks
✅ Ensure operational continuity during GNSS disruptions
✅ Strengthen national security through resilient timing networks
✅ Support critical operations requiring reliable timing infrastructure
Hoptroff is Engineered to be GPS-Independent
