GPS Threat Protection and Security
Overview
GPS Spoofing and Jamming Vulnerabilities in the real world:
Security and protection of a network and Position, Navigation and Time (PNT) application is always a high priority and GPS technology is the key to deployment of these applications. The vulnerability of GPS to interference is not a new phenomenon. GPS signals are extremely weak and highly vulnerable to jamming and spoofing resulting in partial or complete loss of GPS signal. There are certain natural phenomenon like solar flares and other physical environmental conditions which interfere with GNSS signals.

However, these days more and more instances of jamming, complex jamming, and spoofing are surfacing across the globe. The frequency of these events is growing rapidly as reported in the news. It is driven by geopolitical tension in many parts of the world and there are concerns about the next battle front of cyberspace. But there are many other building examples of spoofing (e.g., Uber drivers spoof to change location of their vehicles, Pokemon GO spoofing, intentional drone interference, Fleet tracking interruption, etc….) that are becoming more commonplace and have potential to wreak havoc on critical infrastructure and applications we take for granted that are dependent upon reliable and accurate GPS signal.
Securing Position, Navigation and Time (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.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.
