Assessment of Cyber-Secure GBAS Using Adaptive Beamforming in the Presence of Interference

Daniel Gerbeth, Maria Caamano, German Aerospace Center (DLR)

Session A5: Future Augmentation Systems, Correction Services, and Integrity, Friday, September 18, 08:57 a.m.

Presenter: Daniel Gerbeth

  • Assessing cyber-secure GBAS using adaptive beamforming antenna and receiver on ground and airborne segment.
  • Flight trials under jamming show system maintains carrier-phase continuity and integrity compliance, unlike conventional receivers.
  • Resilient GBAS sustains precision approaches despite intentional GNSS interference.
