The US Defense Department had already spoken up about this bleed through and I believe NOAA/NASA had also expressed strong concerns about the auctioning off these frequencies because they impact satellites from measuring ground temperatures which is important for weather reporting and collecting data for climate change.
So,
Impact to Aviation, Check.
Impact to Military Defense, Check.
Impact to NOAA, GPS, and weather reporting, Check.
They’ll sell it anyway because…Profit!! and wait to clean up the fallout when planes crash and GPS becomes more unreliable.
