''Contrary to the claims of Relativists, the GPS system has never been based on Relativity.  The Time Service Department, U.S. Navy, observed that "the Global Positioning System (GPS) does not include the rigorous transformations between coordinate systems that Einstein’s general theory of relativity would seem to require" in part because "the effects of relativity, where they are different from the effects predicted by classical mechanics and electromagnetic theory, are too small to matter – less than one centimeter, for users on or near the earth.”''

''Only some, but not all effects of relativity are addressed by the [[Global Positioning System]]: not yet incorporated are the effects for fast moving  receivers of the signal (e.g., satellites), therefore the Time Service Department, U.S. Navy, observed that "the Global Positioning System (GPS) does not include the rigorous transformations between coordinate systems that Einstein’s general theory of relativity would seem to require" in part because "the effects of relativity, where they are different from the effects predicted by classical mechanics and electromagnetic theory, are too small to matter – less than one centimeter, for users on or near the earth.”''

Andrew Schlafly changed it back, ignoring my edit comment: ''(changing misleading reference - as explained [[Talk:Counterexamples_to_Relativity#Misleading_Reference|here]] and [[Talk:Counterexamples_to_Relativity#GPS_revisited|here]])''

'''The current statement of Andrew Schlafly is wrong in at least two ways, as explained several times:'''
 +
 +
*the [[GPS]] addresses effects of Relativity: From the very beginning, its builders had the Theory of Relativity in mind. [http://oai.dtic.mil/oai/oai?verb=getRecord&metadataPrefix=html&identifier=ADA058591] and [http://www.navcen.uscg.gov/pubs/gps/sigspec/gpssps1.pdf]
 +
*the paper quoted above addresses ''yet another'' effect.
 +
 +
Perpetuating a wrong statement doesn't seem to be very insightful.
