Resilience Through Responsible Use of PNT

This page provides information and resources for improving positioning, navigation, and timing (PNT) resilience, especially in critical infrastructure.

As stated in the U.S. Space-Based PNT Policy: "The widespread and growing dependence on GPS by military, civil, and commercial applications, systems, and infrastructure make the performance of many of these systems inherently vulnerable if disruption or manipulation of GPS signals were to occur. GPS users must plan for potential signal loss and take reasonable steps to verify or authenticate the integrity of the received GPS data and ranging signal, especially in applications where even small degradations can result in loss of life."
