Perhaps not in the abstract, but on-orbit power is severely limited, and
you can't get more RF watts out of a transmitter than you put in as DC.

Can you imagine the uproar if every GPS bird had a 10 KW transmitter on
board, powered bu a nuclear reactor?

The low received power is a direct consequence of engineering of satellites.
