Eliminating GPS multipath reflections and turbulence induced drift during critical rooftop landings.
Urban glass and concrete facades cause severe satellite signal multipath distortions. Dual-frequency RTK ground base stations broadcast carrier-phase correction vectors directly to the arriving eVTOL via private local 5G, yielding 2-centimeter position certainty.
Modulated near-infrared LED arrays embedded in the touchdown and lift-off (TLOF) area emit encoded spatial geometries captured by the aircraft's ventral machine vision cameras, ensuring landing accuracy even during GPS jamming.
