Statement from DHS on the Ligado License

“The Department of Homeland Security recommended the FCC deny the Ligado license and remains concerned that an approval creates a high degree of uncertainty for our public and private sector partners."

S&T FRG OPSR

The DHS Science and Technology Directorate’s Office for Public Safety Research (OPSR) applies multidisciplinary research and development to strengthen the safety and effectiveness of first responders, the Homeland Security Enterprise (HSE) and of state and local partners.

PNT Program

To address GPS vulnerabilities in critical infrastructure, S&T’s Position, Navigation, and Timing (PNT) Program has a multi-pronged approach of conducting vulnerability and impact assessments, developing mitigations, exploring complementary timing technologies, and engaging with industry through outreach events and meetings.

S&T Resilient PNT for Critical Infrastructure

Accurate position, navigation, and timing (PNT) is necessary for the functioning of many critical infrastructure sectors. Precision timing is one aspect that is particularly important, with one microsecond level or better synchronization often being required by numerous infrastructure systems, such as the electric grid, communication networks and financial institutions. Currently, the primary source of distributed and accurate timing information is through the Global Positioning System (GPS). However, GPS’ space-based signals are low-power and unencrypted, making them susceptible to both intentional and unintentional disruption.

Critical Infrastructure

Critical infrastructure includes the vast network of highways, connecting bridges and tunnels, railways, utilities and buildings necessary to maintain normalcy in daily life. Transportation, commerce, clean water and electricity all rely on these vital systems.
