UBX to rinex conversion issue is only observed when file are converted with RTKLib.
Issue is: when converting RS2 UBX file to rinex using RTKLib, some L2 carrier phase is dropped during the conversion process.
When using EZSurv rinex converter, there is no issue.
A RS2 UBX file and it’s equivalent rinex file, when converted to rinex using EZSurv are similar (L2 carrier phase remains available for all satellites when conversion is made with EZSurv).
That being said, it seems there is an issue with RTKLib converter (issue is only with L2 carrier phase).
PDF file attached shows 3 graphs
L2 carrier phase signal as recorded by RS2 in native UBX format
L2 carrier phase signal for same file, file converted to rinex with EZSurv
L2 carrier phase signal for same file, file converted to rinex with RTKLib (drops of L2 carrier phase are observed on almost all satellites in view)
I have also shared the file (RS2 UBX).
Hope the “Scan obs types” setting can solve that issue. Please advise if you have a solution to that issue.
