“The Resilient PNT Reference Architecture is a major milestone in advancing S&T’s cybersecurity-based approach to PNT resilience,” said Kathryn Coulter Mitchell, Senior Official Performing the Duties of the Under Secretary for Science & Technology. “PNT services, such as the Global Positioning System we may use every day in our cars, are a national critical function that enable many applications within critical infrastructure sectors. For example, timing information from GPS plays a critical role in telecommunications and is used for network synchronization. It is also used for certain protective functions in the power grid.”
“Building resilient systems requires recognizing that even the best of defenses may eventually be defeated by constantly evolving threats,” said S&T Technical Manager Ernest Wong. “By applying cybersecurity principles like Zero Trust Architectures to PNT, we can design resilient PNT systems that can continue to function properly even under the assumption of compromise.”
The Reference Architecture provides a vision for a holistic approach to Next Generation Resilient PNT systems. Careful application of these concepts and techniques can produce PNT equipment that is highly resilient to current and future PNT threats and strengthen critical infrastructure.
