Capture weak GPS signal

Even the default mission offers everything you need: Adjust ref level, center and span: DONE.

GPS signals are far below the thermal noise. No way you can see the GPS signals on a spectrum analyzer, it is deeply buried in the background noise.
In this case you would need to "de-spread" the signal which will add a signal processing gain of around 40dB and then would be around 25dB above the noise floor.
