Title: Beamforming Antennas for Navigation:
How they shape the future of GNSS

Abstract: Modern civilization runs on GNSS, from financial transactions and power grids to maritime shipping and aviation. Yet this invisible infrastructure is being challenged: jamming attacks are surging, spoofing threats are evolving, and even natural interference can cripple critical systems. While algorithms fight these challenges in software, the first line of defense is hardware: the antenna.

In collaboration with the European Space Agency (ESA), my research focuses on beamforming antennas, from phased arrays to novel 3D-printed Luneburg lenses designed to sharpen signal acquisition and reject interference in ways traditional antennas can’t. I’ll discuss the trade-offs of these designs, their current capabilities and results we got, and finally I’ll introduce a GNSS complimentary method we’re developing with Thales Alenia Space based on signal of opportunity (SoOp) using LEO mega-constellations.
