GNSS Security for PNT Applications

To guide operators of Critical Infrastructure sectors such as communications, energy, transportation, emergency services, financial services, and cloud data centers, the Department of Homeland Security (DHS) Science and Technology Directorate (S&T) have described a number of steps that can be taken to mitigate outages and disruptions with GPS reception, thus improving its PNT (position, navigation, and timing)

This paper describes the Microsemi solution for securing GNSS to support PNT applications as used by Critical Infrastructure sectors
