Global Navigation Satellite Systems Engineering, Policy, and Design
For years, both the Executive and Congress have expressed concerns over PNT vulnerabilities and clamored for solutions. Yet little has changed. Three important reports emerged at the tail end of the old regime. As new leadership takes the helm, in which direction will it take the PNT enterprise?

The Department of Homeland Security (DHS) Science and Technology Directorate has published the Positioning, Navigation, and Timing (PNT) Integrity Library and Epsilon Algorithm Suite to protect against GNSS spoofing. These resources advance the design of PNT systems and increase resilience of critical infrastructure to PNT disruptions.
