2026 Agenda

Federal, Civil, and Industry leaders will discuss potential alternative terrestrial-based timing solutions for short-term (hours to days) and long-term (greater than 30 days) disruptions to Global Positioning Systems (GPS) and/or Global Navigation Satellite Systems (GNSS) signals that provide critical time synchronization of communications networks including LMR systems. Attendees will learn of real-world events resulting in significant GPS disruptions, exemplifying the critical need to develop and deploy alternative terrestrial-based timing sources to ensure critical infrastructure like communications networks remain operational. Discussions will also include the National Institute of Standards and Technologies (NIST) offerings, National Association of Broadcasters (NAB), and the use of long-lasting holdover clocks. Finally, explore the need for increased cybersecurity and situational awareness to prevent, detect, and track GPS disruptions.
