Abstract

Officials at the US Department of Homeland Security have called the nation’s over-reliance on GNSS "…a single point of failure for critical infrastructure." This presentation will examine studies and real world instances of GNSS disruption that demonstrate this challenge. A policy and technology roadmap to Protect signals, Toughen receivers, and Augment signals will be presented as a frame work for ensuring national PNT resilience.
