Summary: Last month, DHS’s Science and Technology Directorate published a best practices guidebook to help critical infrastructure owners and operators secure and enhance the resilience of their operations associated with positioning, navigation, and timing services.
Analyst Note: Accurate positioning, navigation, and timing (PNT) is critical for the functioning of many critical infrastructure sectors. According to DHS, precision timing is particularly important and is primarily provided 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. To help critical infrastructure secure their PNT-dependent operations, DHS published the “Best Practices for Resilient Positioning, Navigation, and Timing (PNT) Supporting Critical Infrastructure.”
The best practices guide helps owners and operators understand their role in responsible PNT use. It outlines general best practices, illustrated with specific examples for PNT technology, such as GPS or Global Navigation Satellite System (GNSS), and use cases (e.g., stationary timing or moving platform). By assessing risk and applying these principles, organizations can enhance the responsible development, acquisition and deployment of PNT solutions, according to DHS. This guidance can be used by critical infrastructure owners and operators to assist with planning, development, and use of PNT systems and services.
