Exactly, it is an augmentation system developed for and funded by the
FAA. The notion that WAAS is part of GPS is like saying that NDGPS
or CORS or any other separate systems that use or work with GPS are
GPS systems.

None of the augmentation systems are part of GPS.

And, as usual, your learn-resistance has forced you to post yet another
useless and off-topic repsonse.

It worries me that I see a lot of ignorance of GPS in the aviation
community.

You are mistaking the responses as ignorance because you are refusing to
understand that in aviation, only the application matters to the pilot. We
are trained to use and understand the issues involved in every piece of
equipment in the airplane. That means that we understand the limitations
of non-WAAS-enabled GPS, for example, and why we can't use them for IFR
approach; it is *exactly* because WAAS provides accurate alititude
information. If you disagree, take it up with the FAA, where you will be
told exactly the same things that many of us have told you. Furthermore,
we understand such not-so-subtle differences as whether something is
_measuring_ angles or the timing of signals, and won't fall victim to such
misconceptions. The only reason that you won't fall victim to your lack of
knowledge is that you aren't doing anything real.
