I am more than happy to provide FB. Things are absolutely clearer but the rabbit hole goes on.

Using this new ephemeris data, when it becomes
available, combined with the receiver’s raw data, better fixes can be
computed. This is the basis of PPP.
I think I understand basic PPP it's better clock- and orbit data combined with the raw measurements and this is fed to the PPP algorithm. But what is this RAW data? Are these carrier phase measurements or pseudo range (or both)? Does the post processing solve the '
the carrier phase integer ambiguity problem' in order to reach cm accuracy (known as PPP-AR)? What has improved in the
u-blox ZED-F9P and ZED-F9T chips making this new level of accuracy possible. I still find it strange there is not talk of PPP in their spec's though. It seems to go much further than post processing.
Extra:
I hope my receiver arrives soon but covid-19 is delaying my endeavour.
