Securing PNT as Used by Critical Infrastructure

GNSS-based errors, whether intentional or unintentional, can quickly impact a vast geography and widely dispersed locations. Additionally, a large variety of operational environments must be accounted for that not only includes outside deployment with a clear view of the sky, but highly obstructed locations, urban canyons, and in-building and in-cabinet scenarios.

The following are three main objectives to consider when constructing a secure PNT infrastructure:

Detection—early sensing of threats, both intentional or unintentional
Resiliency—continuous operation until threats are mitigated and resolved
Visibility—measurements and analytics for ongoing PNT health monitoring

This solution for securing PNT focuses on a network approach based on layers of resiliency that can be deployed cost effectively across infrastructure with 10s, 100s, 1000s, or even 10,000s of nodes. These layers are built using a broad array of technologies, including GNSS anti-jamming and anti-spoofing technology, time transport protocols, atomic clocks, and software management and monitoring

The following sections describe the solution with focus primarily on the use of time in Critical Infrastructure. Additionally, although the detection, resiliency, and visibility provided by this solution are applicable to both mobile and stationary applications, the primary target markets for this solution are stationary Critical Infrastructure, such as telecom networks, power grids, enterprise, and transportation networks and data centers.
