DHS S&T initiative targets Positioning, Navigation, and Timing resilience

The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) has published the PNT Conformance Framework to bolster Positioning, Navigation, and Timing (PNT) resilience.

PNT services that include the Global Positioning System (GPS) serve a national function enabling applications within critical infrastructure sectors. The framework would inform the design and adoption of resilient PNT systems and aid critical infrastructure in becoming more resilient to PNT disruptions.

“This is an important milestone in the department’s strategy for building PNT resilience in our nation’s critical infrastructure,” Willian Bryan, DHS senior official Performing the Duties of the Under Secretary for Science and Technology, said. “Combined with our collaboration with the National Institute of Standards and Technology (NIST) on PNT risk profiles, the Conformance Framework will be a valuable risk management tool.”

The endeavor is focused on outcome-based behaviors to encourage industry innovation and creativity in technical solutions. The base provides a common reference point by defining expected behaviors across four levels of resilience.

“Industry has made significant progress in improving PNT equipment, with some manufacturers citing the DHS Best Practices for GPS,” Ernest Wong, S&T technical manager, said. “The Conformance Framework is the next step in helping build resilience into PNT systems within critical infrastructure.”
