Hi Kouki,

I don't think you will see the signal in an FFT window. GPS is spread
spectrum and the signal is below the noise floor. But the signal is
still decodable. 

I thought this was the case; but as someone without any DSP experience this boggles the mind... Does anyone have any more info on GPS or how you decode it even though you cant "see" a signal?
