They definitely appear to use beamforming internally. It appears that the satellite uses knowledge of receiver location (or at least receiver density) to select beamforming codebooks. It's less likely they use this in their mobile coverage, but for their own terminals this is absolutely a thing. https://people.engineering.osu.edu/media/document/2022-10-12/kassas_unveiling_beamforming_strategies_of_starlink_leo_satellites.pdf https://people.engineering.osu.edu/media/document/2022-10-12...
