PANEL
GNSS Jamming: A Growing Threat to National Critical Infrastructure
DAY 2 / 9:45 – 10:45/ CONFERENCE ROOM
Incidents of intentional and unintentional jamming and spoofing of Global Navigation Satellite Systems (GNSS), which underpin vital sectors such as transportation, energy, telecommunications, and emergency services, are on the rise. Experts on this panel will discuss real-world cases, technical vulnerabilities, and the cascading effects of GNSS outages on critical infrastructure, national security, and public safety. The session will also highlight current mitigation strategies, legal frameworks, and possible measures the international community can adopt to strengthen GNSS resilience amid an increasingly contested signal environment and rising geopolitical tensions.
