→Effects of Relativity and the GPS: new section
: SamHB: Thank you so, so much for your comments! You're absolutely right; my page was not up to par, and I was wondering how to better explain exact differential equations (and make my equations larger!) Also, that is a good hobby. My hobby is studying physics/quantum mechanics/relativity, even though I am a mechanical engineer by trade. :-D [[User:PhyllisS|PhyllisS]] 00:55, 31 July 2010 (EDT)

== Effects of Relativity and the GPS ==
You introduced the following quote on [[Talk:Counterexamples to Relativity]]:
''The Time Service Department – a department of the U. S. Navy - states: “The Operational Control System (OCS) of 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 – transformations to and from the individual space vehicles (SVs), the Monitor Stations (MSs), and the users on the surface of the rotating earth, and the geocentric Earth Centered Inertial System (ECI) in which the SV orbits are calculated. There is a very good reason for the omission: 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.” ''
Have you read the article ''GPS and Relativity: An Engineering Overview'' by Henry F. Fliegel and Raymond S. DiEsposti? I don't think that it means what you think it means :-)
I elaborated on this [[Talk:Counterexamples_to_Relativity#GPS_revisited|here]], [[Talk:Counterexamples_to_Relativity#Reversion_of_my_edit|here]] and [[Talk:Counterexamples_to_Relativity#Quote_mine|here]].
I'd like to get your input on this!
