GNSS signals uses spread spectrum technology. You cannot see GNSS signals as a sinusoidal signal if you expect to see so. You can use spectrum power meter properties of your spectrum analyser.

For GPS you can use settings below:

Set maximum RF power from your simulator which is -115dbm/satellite for GSS6300. Open all available channels.

Center Freq: 1575.42 (I assume L1)

Span: 2MHz

Video BW:100Hz

Resolution BW: 10Hz

Attenuation: 0dB

Use can use peak hold properties to see spectrum.
