Potter, is wrong here, as GTR is an integral part of GPS.

[Jan Panteltje]

Wrong, they allowed for a big correction factor in the electronics.
Because they were UNSURE.
The corrections happen.
That does not prove GTR at work.

[GR_Varney]

Oh joy, Jan is a member of the GR ignorant morons that infest Usenet.


[hanson] .... ahahaha... Mikey, it is great to crank folks for cranking's sake at this great and hilariously mad 24/7 cyber party. But in the real world it turns out that both sides (above) are right on this hotly debated issue. GPS was planned, developed, manufactured, deployed and tested WITHOUT the use (nor need) for SR or GR. Only later as GPS sophistication grew, the teacher community got wind of it, and the GPS Sales departments saw promotional value in it did the mania of promoting GPS via Relativity grow which then subsequently infested the Usenet. -- Dr. Eric Prebys of Fermi National Accelerator Laboratory posted the following on this issue on 01 which corroborates that in the early phase of GPS operations NO relativistic calculations where involved or used; Eric saying: "the military types were skeptical of this 'relativity thing' and insisted that the GPS have an option to turn off these corrections in case they turned out to be wrong."

So because the military does not understand GR and its effects on the accuracy of GPS, that means that there are no effects?




-- I hope you don't classify Eric as one of the
GR ignorant morons that infest Usenet, because he let the cat
out of the bag.

Since I don't know who he is, and have not read what he said, I reserve judgment.


Also, it is easy to show that no relativistic calcs are needed for
the "famaous" 38 microsec delay:

Only to the GR ignorant.


m_e/h * 2G/c^2    .........  4.4E-10 s/s
m_e/h * 2G/c^2 *86400 .....  38  microsec/day
where m_e = mass of earth and h being the Space vehicle
height above the earth surface (of radius r_e), and
T being the 12 hrs observation period,
relating to h = ([G m_e/(4 pi^2)]* T^2)^(1/3) - r_e

...AND SO THE BEAT GOES ON...buried under the deafening noise
of the steamroller of history... Yep, noisy as ever! * COOL! *,
but.... Let'em sing!... All of'em... It's a beautiful choir!... ahaha...
AHAHAHAH.........ahahahaha....­.ahahahanson

Umm... whatever. I must assume from your post that you are ignorant in GR. However, the question now is: "Can you cure your ignorance?"

Do some reading, then get back to me.
