Sam,

Ah well, add me to the above list. Serious question though.

Is it not true that any frequency can be used as a clock to measure the
signal flying time? Relativistic effects or not. The GPS receiver extracts
the clock from the signal anyway.

The fact that we have compensated the frequency shift is merely a
convenience to give us a 10MHz frequency standard and a "standard" second
for stationary clocks?

So it is a true statement that GPS does not depend on Relativity just on an
accurate clock provided that we know what that frequency is.

Thanks,
Scotty.

Sammy make's a good point!

What General Relativity needs is users!

It is helpful to see how General Relativity is being under used
compared to another scientific model.

Potter, when one compares predictions of relativity compared
to classical models, relativity wins every time. Methinks it's
time for Potter to embrace relativity, instead of blustering
against it, frothing at the mouth, and whatever.

Some current applications:
o global navigation satellite systems (GNSS)
o particle accelerators, research and medical
o relativity nicey explains many observed phenomina
in astronomy and astrometry

Oh, and Potter, don't forget Relativity, Mass Energy
Equivalence and Nuclear Reactions.

"The result from the theory of relativity that Mass and Energy are
different manifestations of the same physical entity and that it
is possible to convert mass into energy finds an application in
the processes of nuclear fission and nuclear fusion.

"In the process of nuclear fission, a large unstable nucleus such
as that of Uranium-235 decays into two smaller nuclei.
Interestingly, the sum of masses of these two nuclei is smaller
than the mass of the original larger nucleus. This "mass defect"
is responsible for the release of a large amount of energy in this
process of nuclear fission. The difference in mass, when multiplied
with the square of the speed of light in vacuum (that is, c2),
gives the amount of energy released in the process by the famous
equation e = mc^2.

Potter, you would learn an lot if you sat down for a few days with the
reference below... but I suspect that you don't have the academic or
intellectual capability to work through the material and gain insight
for the considerations that must be taken into effect. The last time
you tried or pretended to try... your fixed on an offset value and tried
to convince yourself that it didn't have anything to do with relativity.
Your attitude appears to be, "I can't understand this shit, so therefore
it is wrong, or not needed".

The literature is there for all to learn from... Many sources. It's OK
to admit it is beyond your grasp, Potter. It's OK!

Any frequency will do... What is important is to account for the
difference (due to time dilation) of satellite clocks and ground
based clocks, as they must be synchronized in global navigation
satellite systems. General relativity beautifully predicts those
differences and is incorporated in to the GPS Specs. The later URL
below is a graphic showing the sign and degree of time dilation as
a function of altitude.

Temptation gets the better of me now:

If we beamed you up, Scotty, to one of the GPS satellites, the
relativistic corrections would be applied to the ground based clocks
from your perspective. But the more traditional perspective is for
the ground (or near ground) down on the planet.

So why are you desperately trying to defend relativity? We all know
it has failed two major tests, the LIGO and GPB. What's in it for
you...

Putting aside the fact you have been posting from a VA hospital 5 days
a week every week since September from 9 to 5....

Why is it that people like you have to hide under a pseudonym? Is
making relentless personal attacks made harder when your real name is
associated with them?

How about I start forwarding your messages to the VA abuse department?
I'm sure they'd be interested in knowing government resources are
being wasted in such a way on such a long term basis.

Educating people about the error of Einstein is not a waste of
resources. In fact, the error of Einstein has cost the government a
lot of money. As for you, your education has been a waste of
resources. Your overstaying in school is a waste of school space for
other students, professor's time, and other incidental resources. If
you are concerned about waste, why not do something productive, like
graduating on time.

Don’t you love the whining arguments of Einstein Dingleberries. In
one instance, they are trumpeting mass-energy equivalence. In another
instance, when it is pointed out to them that the Cosmological
constant representing negative energy density in vacuum must also
indicate negative mass density. This concept is utterly ridiculous as

As I indicated, what General Relativity needs
are USERS, not more conmen, cultists, propagandists,
babble-masters, and parrots.

I was disappointed to see that Sammy
tried to create all kinds of strawmen, and that he
posted the same old references to papers
written by self-serving General Relativity Gurus
on the taxpayer dole,

rather than posting about how the General Relativity Gurus
are serving society and making lots of money
by using their powerful, esoteric knowledge,

like the people who possessed information on
integrated circuits, RADAR, fibreoptics, LASERS,
digital communications, digital computers, networking, DNA, etc.

General Relativity must be great
because Time Magazine, the New York Times,
and the Washington Post declared it the
greatest intellectual achievement of all time,
and made Einstein the "Man of the Century".

If they wrote, it must be true.

No wonder we can not convince them that relativity is wrong.  They are
simply not intelligent enough to elevate their understanding.  They
must be so happy ekking out a meager salary, living in a duplex, and
driving a 10 year old corolla that they think upholding the status quo
of relativity keeps them in their great positions in life...

I don't have a stake in this fight. I am simply looking to learn.
The difference between the clock speed on the GPS satellites and the
speed that the same clock would run at on the ground appears to be
well established. I would be interested to learn of any published
papers that show a calculation of what the clock speed difference
should be, using effects other than relativity.

Or, could one of the "relativity doesn't exist" folks detail a
calculation of what the clock speed difference should be, using the
causes that you consider as most likely. If your approach is valid, I
would expect that it should yield the clock speed difference that has
been observed on the GPS satellites.

Have a good day.

There are no definitive requirements to say the satellite clock

For example, the satellite clock can all tick at 1.000GHz +/- 0.5Hz
while the ground clock can tick at 577.9874MHz +/- 10.67MHz.

When your receiver receives almanac information from four satellites
with each giving its time, altitude, longitude, and latitude, you can
form a set of four equations with four unknowns. The unknowns are
your satellite time (nothing to do with ground time), your altitude,
your longitude, and your latitude.

Professor Andersen knew this, but trying to promote the nonsense of SR
and GR, he proposed a fairy-like mysterious function to the GPS where
this mystic function requires the synchronization of the satellite and
ground clocks. Professor Roberts recently understood this. In doing
so, you also proposed a top-secret military function built into the
GPS that also requires the synchronization of the satellite and the
ground clocks. It becomes a faith issue. However, I call the bluffs
of these professors. I do not buy the mysticism they try to promote

===============================
No "clock speed difference" has been observed, other than the normal
differences one would expect from one clock to another. My wrist
watch doesn't keep exact pace with my computer, neither do I expect
it to as long as it is reasonable and +/- 3 minutes a year is adequate.
I can still time a car journey with it as accurately as I'll ever need.
Indeed, no two satellites keep exactly the same time either, and
there are FIVE atomic clocks being averaged at the US Naval
Observatory, so obviously they don't keep exact time individually
either.
The Tom-tom or Garmin sat-nav that almost everybody owns these
days doesn't have an atomic clock, therefore nobody is finding a
difference between the clock speed on the GPS satellites and the
speed that the same clock would run at on the ground. Yet these
devices work to everyone's satisfaction, the main complaint being
map errors, not positional errors, which remains +/-15 metres
horizontally. Quite simply, the device only uses satellite time.

To say that relativity is needed for GPS to function is as ridiculous
as saying the weight of an ant needs to be known to weigh an elephant,
only a crank fanatic would make such a claim.

What kind of lunacy prompted Einstein to say
the speed of light from A to B is c-v,
the speed of light from B to A is c+v,
the "time" each way is the same?

Here it is:
http://www.fourmilab.ch/etexts/einstein/specrel/www/figures/img22.gif

The dorks will deny he ever did.
According to Cretin [email protected]

Easy: he did NOT say that.
According to cretin van lintel, Einstein did not write the equation he
wrote.
________________________________________________________
According to Imbecile Jimmy Black:

" In neither system (meaning frame of reference in modern-day terminology)
is the speed of light c-v or c+v. In both systems the speed of light is c."

According to Imbecile Jimmy Black, Einstein did not write the equation he
wrote.
________________________________________________________
According to Cretin Dork Bruere

I don't give a damn what Einstein wrote.
________________________________________________________
According to Lying Little Shit Matthew Johnson

And even the question is wrong! For he never said any such thing.
This should be painfully obvious from what he _did_ say,
namely, that the vacuum speed of light is a constant of nature,
invariant under all admissable [sic] transformations between
inertial reference frames.

Apparently LLS Matthew Johnson has rewritten Einstein's paper.

A team of scientists working under the direction of researchers from the
University of Sussex have recently discovered that Einstein did not say
"inertial".

According to LLS Matthew Johnson, Einstein did not write the equation he
wrote.

According to Chief Wanker Uncle Stooopid Schwartz:

"c+v appears nowhere in the paper, nor could it. [sic]
