I note that
411A has renewed his new-years resolutions for jumping in the deep end, blowing trumpets, and being ill informed.
The European position is being managed and well thought through by Eurocontrol; individual nations contribute to the plan, see a paper from the UK CAA,
GPS Integrity and Potential Impact on Aviation Safety
A publication search for GPS in the CAA web site will find other documents.
I understand that the European position on the use of GPS for high integrity approach and landings (Cat1 +) is that any system will require dual channel integrity, which implies using both GPS
and Galileo.
>>The USA acts...the Europeans just look on in amazement, and continue to cast stones, simply because they didn't think of it first<<
Of course
411A this applied to the Microwave Landing System (MLS) didn’t it? Or was the situation that the US grand plan for GPS was to quickly supersede MLS, forcing its untimely demise in the early 1980’s, thus killing the European lead and commercial potential.
Edit: Also see a more digestible document, with some applicability to commercial operations
