Description
Global Navigation Satellite Systems (GNSS) underpin everything from aviation to critical infrastructure – but their weak, unencrypted signals make them dangerously vulnerable to jamming and spoofing attacks. This research explores a novel, low-cost solution: a Luneburg lens, a 3D-printed, multi-beam antenna system that enhances signal reception while inherently resisting interference. Unlike traditional mitigation techniques, the lens leverages directional gain to strengthen legitimate satellite signals and suppress off-axis interference, while also offering potential spoofing detection through anomalous signal reception patterns. Real-world testing at Norway’s 2025 Jammertest demonstrated that, even under intense jamming, the lens-enabled system maintained satellite tracking where a standard patch antenna failed completely. These early results suggest that Luneburg lens technology could offer a practical and scalable path toward more resilient GNSS systems in increasingly contested environments.
