When I start RTKNAVI with settings shown in the link, RTK is not able to display the satellite SNR for the 6M module, for same settings I am able to see the SNR for 7P module and the module is working fine with U-center. I tried replacing the rover and base station still for 6M it does not show the SNR. But in streams it shows data is coming continuously. </div><div style="font-size:12.8px;"><br></div><div style="font-size:12.8px;"><a rel="nofollow" target="_blank" href="https://docs.emlid.com/navio/RTKLIB/rtklib-rover-setup/" style="font-size:12.8px;">https://docs.emlid.com/navio/RTKLIB/rtklib-rover-setup/</a><br></div><div style="font-size:12.8px;"><br></div><div style="font-size:12.8px;">Please help me. </div><div><br></div><div>Regards</div><div>Bipin Aadaki</div></div></div><br>_______________________________________________<br>This message is sent to you from <a ymailto="mailto:FOSS-GPS@lists.osgeo.org" href="mailto:FOSS-GPS@lists.osgeo.org">FOSS-GPS@lists.osgeo.org</a> mailing list.<br>Visit <a href="http://lists.osgeo.org/mailman/listinfo/foss-gps" target="_blank">http://lists.osgeo.org/mailman/listinfo/foss-gps </a>to manage your subscription<br>For more information, check <a href="http://wiki.osgeo.org/wiki/FOSS-GPS" target="_blank">http://wiki.osgeo.org/wiki/FOSS-GPS</a><br><br></div> </div> </div> </div></div></body></html>
