Application/Impact of PNT Technologies in the Homeland Critical Infrastructure
This session will focus on the use of PNT technologies in the critical infrastructure with emphasis on discussing usage, vulnerabilities, and providing mitigating solutions to safeguards against threats to the critical infrastructure. PNT based technologies, such as GPS, are now an integral part of the national critical infrastructure. Many sectors rely on some aspect of PNT ranging from timing for communication systems to clock synchronization for power transmission in the electrical grid. The growing use of PNT along with potential threats and vulnerabilities to the critical infrastructure such as the electrical grid, communication, transportation, finance, and emerging infrastructure for domestic employment of UAV systems creates a challenge for safeguarding national assets and maintaining homeland security.

PNT Situational Awareness 1
PNT Situational Awareness (PNT-SA) refers to the detection, characterization, attribution, and geolocation of intentional, unintentional and naturally occurring threats to PNT. PNT-SA can detect threats to allow for engagement of measures which afford increased robustness and resiliency and also help balance the need for them by 1) providing information to the individual user/host system to recognize the presence of threats and inform decisions as well as tactics, techniques, and procedures (TTPs); 2) contributing to local or wider area awareness of contested and impacted regions to inform movement and maneuver as well as future planning; and 3) providing important information to enable threat removal via kinetic, legal, or other means. While PNT-SA capabilities may not directly mitigate the impact of threats to the same extent as robustness and resilience approaches, it might be possible in some cases to field them more quickly with significantly less resources. The goal of this session is to bring together government, industry, and academia to discuss the state-of-the-art capability and plans to exploit new algorithms, approaches, and visualization schemes that leverage new types of sensors and data, ranging from publicly available cellular data to collections made from new space-based constellation, for PNT-SA in support of a variety of government and safety-of-life applications.
