All that is needed is to aim precisely. GPS and satellite data again.

I bet a good long telephoto lens set to infinity would work - back it with
a bandpass filter set to the transmitter's wavelength and a photomultiplier
or image intensifier..

I have an photomultiplier tube (from a scintillator) that I have never
found a use for..
