::::You've now been presented with many sources from Rutm and I supporting GR implementation in GPS, and you have yet to produce one source that says that GPS works on only classical principles. Furthermore, I question your motivation in demanding one "best" source, since I anticipate that you will attempt to attack the "best source," perhaps by invoking "liberal bias" (as if it existed in this case--either the clocks run at different frequencies or they don't), ignoring the vast consensus, and proclaim "victory."--[[User:Bayes|Bayes]] 10:56, 27 July 2007 (EDT)

:::: OK, I think I now (finally!) understand what's going on. I think we have a misunderstanding here; we're talking about two different kinds of corrections. The paper supplied by Rutm (and quoted in the current article) is discussing relativistic corrections to the frequency of signals measured by the receivers. That paper is from the early 1990s, and at that time no relativistic corrections were performed for those signals (though corrections might be taken into account now). Throughout this discussion, I have been referring to the fact that clocks on GPS space vehicles have ALWAYS had built-in frequency offsets to account for the relativistic effects on moving clocks and clocks in gravitational potentials. It's a question of corrections made to the '''communications''' between GPS components and the '''on-board clocks''' of the satellites; the former are not as important, while the latter are very important. Any problems with inserting this nuance into the article?--[[User:Bayes|Bayes]] 19:14, 27 July 2007 (EDT)
