"The assessment results also indicated that the current GPS system cannot
meet the RNP in most of the cases and the current integrity monitoring
mechanism is inadequate for providing the necessary integrity monitoring
capability. Therefore, this study suggests that augmentation systems are
needed to support the navigation function for all phases of flight." Jan.

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.

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