Does Skydel calculate the C/N0 directly? if not, does it help me to calculate it (estimate losses, gains, powers. etc.)?

Hi @mohdyaser,
The “reference power” for all GNSS signals generated by Skydel is around -130dBm. A slider set to “0 dB” will force the signal to be at -130dBm:
When Gaussian Noise is activated, Skydel generates noise such the ratio between a simulated GNSS signal at -130dBm and the thermal background noise will be C/NO = 44 dB*Hz.
When generating RF signals with Skydel connected to an SDR radio, the measured signal strength will be dependent on:
- Your Skydel configuration settings
- The radio gain
- The losses of RF equipment
- Etc.
In this case, you will need to perform a manual CN0 measurement.
