Driven by US federal government’s executive order 13905 of February 2020
• Protect critical gov/industry infrastructure against PNT disruptions from
GPS/GNSS jamming/spoofing and network security cyber threats
• Define critical infrastructure under national security threats
• Power grid
• Finance
• Transportation
• Communications
• Data centers
• Use published PNT assurance guidelines in progress and evolving
• DHS’s resilient PNT conformance framework (IEEE P1952 resilient PNT UE working group)
• NIST’s cybersecurity framework for PNT profile (NISTIR 8323)
What is the aPNT mandate?
