You have to use Ucenter to enable ubx protocol in Message table (Right Click on UBX then click to Enable).
Then you could use RTKLIB 2.4.2 part 10/11 to extract *.ubx file to *.obs and *.nav file.
Hope this could help you.
Thanks for your reply. I could disable NMEA. However, there are no observation RINEX when I use RTKLIB to convert UBX to RINEX.
Did you get the same problem ?
I would like to take raw data to test our software. We need Rinex…"
Thank you so much for your reply on my question.
I got it. But how to disable NMEA message ? Could you take some guidance for me?
Because I see on the protocol it changed b/w UBX and NMEA.
Thank you very much.
