What is the best way to protect data centers and mobile devices from spoofing and jamming?

“After speaking to our head of engineering, Roger Hart, he explained this as something akin to ‘What’s the best way to achieve world peace?’ As the strengths and vulnerabilities of static and mobile devices vary considerably, the best solution will be achieved through a tailored application of algorithms, antenna siting and design, multi-constellation, multi-frequency and non-GNSS inputs.”

“Spoofing and jamming presents a very credible threat today to users of GPS for navigation and perhaps the greatest threat is vulnerability within our national infrastructure to spoofing of GPS timing. Congress, recognizing this threat, has tasked the Department of Transportation (DOT) in the National Timing Resilience and Security Act of 2017 to provide a backup for the timing component of the GPS. Specifically this backup is to ‘ensure the availability of uncorrupted and non-degraded timing signals for military and civilian users if GPS timing signals are corrupted or otherwise unavailable.’ Although the act directed the DOT that this system should be operational in two years (2019), little progress appears to have yet been made in deploying a backup timing system. This system not only would reduce vulnerability to spoofing for timing users, but could also be used by mobile users for detection of spoofing, allowing for national alerting when jamming or spoofing is detected. These alerts, tied with a quick response mechanism for law enforcement to take action, would provide an effective method for protecting all GPS users nationwide from jamming or spoofing.”

“Take full benefit of multi-frequency multi-constellation redundancy.  Perform signal monitoring and authentication using advanced receiver architectures and signal-based protection (e.g., Galileo’s Open Service Navigation Message Authentication). Foresee non-GNSS redundancy to bridge gaps, such as precise clocks for data centers or IMUs for mobile devices.”
