Get the signal to noise ratio of the satellites in view from the NMEA $GPGSV sentence
The SNR(Signal-to-Noise Ratio) of the satellites in view is returned in the $GPGSV NMEA sentence.
To get the Signal-to-Noise Ratio of the satellite,
- Connect the GPS device to the AT Command Tester tool.
- The tool will automatically parse the NMEA Signa-to-Noise of the satellites from the $GPGSV sentence and display it in the UI.
- NMEA SNR is returned in db.
Learn more on how to use NMEA in the NMEA GPS tutorial.
Try the AT Command Tester tool.
