Unaugmented GPS has insufficient integrity monitoring.

I looked at the link you posted. It seems to be a summary of what is
intended to be presented at a seminar, with no associated evidence. It is
also not clear as to what Shaojun's definition of "inadequate" is.

It is not clear to me what method of integrity monitoring is going on in
the British airspace to which Shaojun refers, but it seems to be
unaugmented RAIM.

The summary indicates that his study "route" was London to New York. But
my understanding is that trans-oceanic flights have to have multiple
navigation systems, only one of which can be GPS.

What is clear is that Peter has a tad more ego than knowledge.
