Resilient PNT: How to Detect, Protect and Prevent Disruption of GPS/GNSS/PNT Signals and Sources

For the last two decades, reliance upon GPS/GNSS for positioning, navigation and timing (PNT) by civilian applications has been an overwhelming success, providing increasingly accurate and reliable PNT information everywhere for free. However, in recent years, malicious threats have emerged that exposed the Achilles heel of GPS/GNSS: Its weak power and unencrypted signal format leave it vulnerable to jamming and spoofing. The loss of PNT information can result in rare but catastrophic events, crippling critical infrastructure that is necessary for our survival. Fortunately, there are many alternative technologies available to augment GPS and provide accurate and reliable PNT information even under extremely adverse conditions.

In this white paper, we will discuss alternative technologies and offer recommendations for procedures and processes to manage and avoid the risks of cyberattacks, applying the best practices known today. We will focus on Resilient PNT and describe the strategies, technologies and procedures to avoid these cybersecurity risks and ensure the continuity of any critical operation.
