I am using cssrlib without DLL error in Windows 11. For pysolid, it may be the cause of the issue, please try to disable it.

thanks for your feedback! will disabling pysolid impact the results? (no tide corrections will be made?)

[hirokawa]

In pppssr.py, there are lines:

    self.nav.tidecorr = uTideModel.IERS2010
    # self.nav.tidecorr = uTideModel.SIMPLE

Please comment the 1st line, uncomment the 2nd line. In this case, the simplified tide model is used instead of IERS2010. I think that the performance difference is very small.

thank you very much, it runs now without any errors using the simple model.
