windup correction issue

hello there,

windup correction in windupcorr function in ppp.py is different from that in rtklib with the same inputs.

is this an error or what?

thanks

satellite pcv/pco correction issue in pppssr

I find that there is satellite pcv/pco correction for measurement in zdres function in pppssr.py .
But I think normally we do not correct PCO for satellites in ssr mode as the orbit correction(dx,dy,dz) is based on broadcast ephmeris.

Is there any problem?

Best regards.

Error Occurs When Decoding Galileo-HAS and Outputting as File

Dear Dr. Rui Hirokawa,

Thanks for providing the compact PPP/PPP-RTK toolkit.
I can really learned a lot following your tutorial.

However, I found one issue when decoding Galileo-HAS and output the result as a file.
In the "self.out_log()" function of "cssrlib.py", when "self.subtype == sCSSR.CBIAS", you get the keys like this:
for sig_ in range(self.lc[0].pbias[sat_].keys()):
However, the "range()" function doesn't seem to support arguments of type 'dict_keys'.
The similar issue also arises when 'subtype == sCSSR.PBIAS'.
In my attempt, removing the “range()” function allows the program to run normally.
If I have misunderstood, I humbly request correction.

Best regards

Decoding code bias of B2b message

Dear Dr. Rui Hirokawa,

Thanks for providing the compact PPP/PPP-RTK toolkit.
I can really learned a lot following your tutorial.

However, I found one issue when decoding the code bias from BDS-B2b augmentation message.
The scale factor in ICD is 0.017, however, in the CSSRLIB, the scale factor is set as 0.02.
It seems that the scale factor is not reset in cssr_bds.py.
If I miss anything, please let me know.

Best regards
