"These correction messages are then broadcast through communication
satellites to receivers onboard aircraft using the same frequency as GPS."

The communication satellites mentioned are not GPS satellites.

But that's just the FAA, what do they know. Obviously you got better
information from your flight simulator manual.

No, I got my information from the original GPS specifications, years ago,
along with some later reading to try to keep up on trends. That's one reason
why I'm able to distinguish between communication satellites and navigation
satellites when I read about them, which helps prevent me from saying foolish
things in open discussions.

Your statement, I quote was "They do contribute to WAAS, but there are no
satellites in that." There *are* satellites in that, so you are wrong.
100% wrong. Admit it and stop weaseling.

Not to mention "contribute to WAAS" being off the mark.

It's worth pointing out that the GEOs also being used to provide a
separate ranging source (bent pipe) in addition to the information
being supplied (corrections, integrity, etc.) in the WAAS messages.
