Hello, thank you for the comment.
For the phase wind-up correction, CSSRlib currently supports two methods (IGS standard model and the model used in QZSS CLAS PPP-RTK).
I assume that the IGS standard model could output the result which is similar to the model used in RTKLIB.

OK, many thanks. CLAS may handle this correction in its own way.
