	I doubt that geosynchronous satellites cause any problems for
radio astronomers.  First, I assume designers of satellite systems
would have made the downlink frequencies ones that were quiet for
their own sakes.
	Second, the satellites are low enough so that if one radio
astronomy setup is disturbed, another will be able to pick up the
signal.
	Third, radio astronomers' targets are not stationary in the
sky.  Nor (as I understand it) does their equipment necessarily
require long, uninterrupted exposures.  It may merely be necessary to
snip out (say) seven second segments every four minutes.
