Processing of CNES real-time products (CNT) with CSSRLIB

[agrenier-gnss]

Hi,

First of all, thank you for the developers of this software, it is really made well made and is very useful for SSR processing.

My issue is related to PPP processing with the CNES real-time products (CNT) accessible here.

I am having some trouble processing this products with CSSRLIB, as it lead to large biases (0.5 - 1m) that slowly drift with time. As it works fine with other products (COD0, GBM0) I understand the major issue is related to differences in the CNT products themselves.

So far, I got that the CNT products are reference to APC instead of CoM. I tried to modify the software to apply a similar offset strategy as the QZS_MODOCA case, without any luck.

Is there a configuration that can be used with CSSRLIB to enable processing of the CNES CNT in current state of the software? Additionally would anyone have a suggestion on the specific processing strategy for these products compare to products from other centre (e.g., COD0)?

I understand my question is not only related to the CSSRLIB software itself and it more of an open PPP processing question. In such, please let met know if I should remove the post from here.

Thank you in advance for your help!

Thank you for comments. Although I never tested CNES stream with CSSRlib, I suppose that RTCM SSR from CNES can be supported. I will check this issue within weeks.
