The U.S. Department of Homeland Security (DHS) Science and Technology (S&T) Directorate recently published a GPS Receiver Whitelist Development Guide and a new release of the Positioning, Navigation and Timing (PNT) Integrity Library in an effort to protect against GPS spoofing.
The free resources are intended to advance the design of PNT systems and increase resilience of critical infrastructure to PNT disruptions. “We hope this guide and related resources will help industry advance towards a cybersecurity-based approach to PNT resilience,” said S&T Technical Manager Ernest Wong.
“Since GPS signals can be jammed or spoofed, critical infrastructure systems should not be designed with the assumption that GPS data will always be available or accurate,” said S&T Project Manager Brannan Villee. “Application of these new tools will provide increased security against GPS disruptions, however.”
