Protection for Position, Navigation and Timing (PNT) Used by Critical Infrastructure

Position, Navigation and Timing (PNT) threats resulting from the vulnerability of GNSS signal manipulation and degradation such as spoofing and jamming is on the rise. The Department of Homeland Security (DHS) recently published the Resilient Positioning, Navigation, and Timing (PNT) Conformance Frame- work document providing a common reference point to help critical infrastructure become more resilient to PNT disruptions. The BlueSky GNSS Firewall Software, Release 3.0 provides new features and security hardening for the BlueSky GNSS Firewall to meet the highest levels of resilience as defined by the new PNT Conformance Framework.
