Not that easy, alas.  Different and often unpublicized frequencies,
unorthodox modulation schemes (it ain't yer normal video signal),
probably encryption for the spysats, possibly tight-beam transmission
with small footprints for the military stuff, and finally the general
problem that most of the satellites in question are in low orbit, meaning
that they aren't in line of sight when they're viewing the Kremlin!

It is possible -- I've seen weather-satellite images, in particular, from
amateur equipment -- but not simple.
