I had a chance to visit the Deep Space Network facility at Goldstone several years ago (definitely worth a visit if you can arrange one). The antennas they use vary in size from 26 to 70 meters in diameter, and even then they need to use lots of process gain because the signal is still several dB below the noise floor. Amateur tracking would probably be incredibly difficult.

- DigitalJack 9y agoJust as a reference point, GPS signals are below the noise floor as well. Typically by 20dB.
