Timing issues: small cause – big effect
Sync failures can cause tremendous damage
GNSS
attack
• Attack falsifies syncphasor timestamp
• In consequence, mid-voltage circuit breakers are activated
• Local overload impacts middle- and high-voltage network
• Many local issues create regional outages

• $1B/day in economic cost if GPS/GNSS is disrupted
• T (timing) is a key enabler of PN (positioning and navigation) capabilities
• US Federal Executive Order 13905 on resilient PNT to protect critical infrastructure
• US resilient PNT initiatives:
- DHS Resilient PNT Conformance Framework (now under IEEE P1952 standardization)
- NIST Cybersecurity Framework for PNT Profile
• US DHS Resilient Conformance Framework – four resiliency levels:
- Level 1: 1 PNT source
- Level 2: 2 PNT sources
- Level 3: N PNT sources
- Level 4: next-gen PNT systems
What is resilient PNT and why do we need it?
