http://en.wikipedia.org/wiki/Stress_(physics)
Stress was introduced into the theory of elasticity
by Cauchy around ***1822***
Cauchy's stress principle asserts that when a continuum body is acted
on by forces,
there are internal reactions throughout the body.
Based on this principle, Cauchy demonstrated
that the state of stress at a point in a body
is completely defined by the
*** nine components of a second-order Cartesian tensor ***
called the Cauchy stress tensor
http://en.wikipedia.org/wiki/Augustin_Louis_Cauchy
Augustin Louis Cauchy (21 August 1789 - 23 May 1857;
was a French mathematician.
His daughter indicated that his final words were "Jesus, Mary, and
Joseph."
Considering the race/religious bias of the Mass Media,
it is not surprising that the mass media uses Einstein
as their Poster Boy for Cauchy's great intellectual works,
much as they made Salk and Sabin Poster Boys
for the works of John Enders
in ending the scourge of polio.
Of course, as folks knowledgeable in science understand,
although Einstein applied Cauchy's stress and strain model
to the entire universe
it is not valid for modeling spaces occupied by sentient beings,
and is not a viable, cost-effective model
that sentient beings can use
to shape and control their world.

I join you in celebrating that there has never been a prediction
for relativity that's been contradicted by an observation. Pretty
good theory so far.
[snip]
That irrelevant screen can be condensed into two sentences:
a) Tom Potter learned that Cauchy had something to do with tensor
analysis, which GR uses.
b) Tom Potter still has no explanation for why the GPS works.
Poor Eric can not give a reason that they remove the clock malfunctions
for GPS to work at all.
If time really changed, why would we need to remove that "change"
to fix "time" to work correctly for GPS.
Again Eric proves he has no clue about the proper function of a clock.
:)
All you've done is validate the concept that math is used in physics.
I suppose next you'll say that I cannot use Laplace's equation to
solve a physics problem because I'd be stealing it.
I am disappointed to see that I did not make my point
clear enough so that everyone could comprehend it.
My points were that
although Einstein has been deified by a friendly media,
and declared Time Magazine's
"Man of the Century"
thus conditioning millions of impressionable people
that Einstein's models such as General Relativity
that wastes time, money and minds
on such pursuits as time travel, warping through space,
worm holes to dump radioactive waste into,
the birth and death of the universe,
and the mind of God,
is more important than such models
as the DNA model which is used to
improve health, fight crime, improve food production,
reconstruct history, etc.,
and that Einstein basically ripped off others
such as Cauchy, Maxwell, Fitzgerald, etc.
and gave them little or no credit for their works.
The bottom line is that Einstein is the Poster Boy
of Jews in the Mass Media who brainwashed the
ignorant masses to think that a Jew was the most
intelligent man of all time, and naturally
that this reflected on them and their proclamations.
One can just look at America's economic situation,
Wall Street, and the Iraqi War to see how valuable
the Jewish input to the American system has been.
I am pleased to see that my pal Gisse,
wants to know how the GPS system works.
1. Light travels at a constant speed
of 299 792.458 meters per second
in the absence of matter,
and in media with sparse matter,
such as the Earth's atmosphere.
2. Time interval measurements of E-M waves in air, and space,
are equivalent to distance measurements.
distance = time interval * C
3. Synchronized clocks can be used to
quantize the distance between the points
by measuring the time it takes light/radio waves
to travel from one point to another.
Clock(A) sends a message that it is time(X).
Clock(B) notes that it is time(X) + I1 on its' clock.
The distance between the clocks is
I1 * C
In other words, systems of synchronized clocks
can quantize the distances between the clocks,
by transmitting the time at each clock's location.
Any clock can determine the distances
between it and other clocks,
by simply determining time(I) for all of the other clocks.
For example,
if one measures a time delay of "I1" of a radio wave
from New York, they must be somewhere on
the surface of a sphere, with a distance radius of I1 * C,
centered about New York
If they also measure a time delay of "I2" of a radio wave
from San Francisco, they must be somewhere on
the surface of a sphere, with a distance radius of I2 * C,
centered about San Francisco.
If they measure both,
they must be on a circle represented by the
intersection of the two spheres.
As can be seen, the measurement of a third point,
would be the intersection of the circle with
another sphere, and would let tell the observer that
they are on one of two points.
A fourth measurement would resolve the situation,
and tell them at which of the two points they are
located.
4. As the GPS satellites are moving,
whereas New York and San Francisco are located
at fixed points (With respect to Earth bound observers.),
it is necessary that GPS receivers know where
the satellites were when they transmitted the time.
This is handled, by having each satellite
transmit its' position in space, along with
the time data.
Each satellite not only transmits where it is ("ephemeris data"),
it transmits its' orbital data ("almanac data"),
along with its' time.
The "ephemeris data"
serves the same purpose to the GPS receiver,
as the Sun does is to a sailor with a sextant.
5. Ground stations continuously monitor
the satellites' orbits and transmissions,
and when changes exceed certain amounts,
signals are sent to the offending satellites,
updating their "almanac data", their "ephemeris data",
their time settings, and drift in their clocks
with respect to the master clock on Earth.
In other words, the ground station monitors the data
transmitted by the satellites and when necessary
sends them signals that tells them, that their
clock is x nano-seconds fast, their orbit has changed to
such and such (Perhaps because of dust drag, etc.),
that their "ephemeris data" should be xxx, etc.
The GPS clocks are set,
to some reference time,
just as your digital watch is,
the only difference being that
the ticks are far more stable, and much finer,
nanoseconds, rather than tenths of seconds.
Drifts in oscillators are corrected by
inserting "ticks", and by adjusting
divider circuits to divide by the desired count.
6. As portable GPS receivers do not have
extremely stable oscillators, they must
derive precision times from the satellites.
As the satellites are at an altitude of about 11,000 miles,
(From the center of the Earth.)
and radio waves travel 186,000 miles in one second,
it takes about .006 seconds for the
time, ephemeris, and almanac data
to reach a sea level receiver.
This means that in a typical transmission,
the GPS receiver must subtract about .006 seconds
from its' clock, in order to set its' clock.
GPS receivers receive and average the times
from several satellites, and recursively
home in on the master time, and make an adjustment
for recursively computed position of the satellite.
In other words, at the reception of the first data,
the GPS receiver knows the master time to about .006 seconds
higher than the first time it receives,
and as it picks up signals from other satellites,
and recursively computes the distances to the
satellites, and averages out multi-path signal variations,
its' own clock homes in on the master clock time.
As the satellites take about 12 hours
(43200 seconds) to orbit the Earth,
and the ephemeris data takes about .006 seconds
to reach the receiver, this means that
the GPS receiver knows where the
satellite is to an accuracy of about one part in
43000 / .006 = 71600000 parts,
even without clock and ephemeris corrections.
Considering that the Earth is about
24,000 miles or 126,000,000 feet in circumference,
this amounts to a sphere of uncertainty of about
1.76 feet at sea level.
7. The clocks used in the GPS system are extremely stable.
They have a long term and short term stability
of about 1 part in 10^14 over one day and even months.
As there are about 3 x 10^13 MICROseconds in a year,
this means that the GPS clocks can maintain microsecond
agreement for over a year, even if no corrections are made.
But of course, adjustments ARE made to the clocks
on a regular basis by a ground clock,
to which all of the GPS clocks are referenced to.
8. As the satellites have a life expectancy of about 10 years,
their orbits are very stable.
In other words, when ground stations get a fix on a satellite's orbit,
we know pretty much where the satellite will be for a long time, and
GPS receivers on the ground have an extremely dependable target to
sight on
9. There is some variation in the time it takes the
signal to reach the receiver due to multi paths
taken by the radio wave to the GPS receiver,
so GPS receivers are programmed to compute out the
multi-path variations, and to compute the time,
using the most reliable data it gets from
several satellites.
10. The GPS satellites broadcast on two carrier frequencies:
L1 at 1575.42 MHz and L2 at 1227.6 MHz.
They transmit a "coarse acquisition code" at 1.0 bits per nanosecond
and
a "precision code" at a bit rate of 10.230 bits per nanosecond.
Frankly the usefullness of the "precision code" is vastly overrated
as current commercial GPS receivers have the capacity to
phase lock with the carrier frequency.
As light travels at about 300,000,000 meters per second,
or 300 meters in one micro-second,
a one nano second error would result in an error sphere of about .3
meters
( One foot), and a 10 nanosecond error would
result in an error of about 3 meters or ten feet.
By averaging data from multiple satellites,
a receiver can reduce the timing uncertainty
due to multipaths, and can reduce the error sphere
by only averaging where the error spheres
of several satellites overlap.
The single largest contributor to time transfer uncertainty is path
delay,
the delay introduced as the signal travels from the satellite
to the receiver.
In order to measure the time interval most accurately,
a quasi-random code is used. The GPS receiver performs
a auto-correlation on the quasi-random signal
in order to eliminate the jitter in the leading edge
of the transmitted signal, caused by transmitter noise,
receiver noise, environmental noise, multipath signal combining,
jamming, etc.
In other words, a segment of the quasi-random signal is
incrementally delayed, and multiplied by the signal stream.
If two string of random numbers are multiplied,
a maximum occur when and if the strings match,
otherwise the product tends toward zero.
The Military can play games with the GPS signals by
juggling the "precision code" signals,
and thus messing up the accuracy
to which a GPS receiver can the time interval.
In summary, the largest contributor
to time transfer uncertainty is caused by
variations path delay, due to signals reflected
off mountains, buildings, etc., and as note,
much of the path delay errors can be averaged out,
because the satellites are moving, and signals
are received from several satellites.
The best GPS receivers can,
by using the methods addressed above,
reduce the uncertainty in time to about one nanosecond,
which amounts to a sphere of uncertainty of about one foot.

....and uncorrected clock drift is measured in tens of nanoseconds per
day. Welcome to why GR is used in the GPS.
Sam is right when he suggests that General Relativity
is a "Pretty good theory"
if sentient beings aren't in the loop.
The bottom line is:
If you want to model
where no sentient being is, or has gone before,
use the stress and strain ideas and methods
of the Frenchman Cauchy (General Relativity).
On the other hand,
if you want to model times and spaces
occupied by sentient beings
use the mechanical and electro-magnetic
ideas and methods of the Englishmen, Newton and Maxwell.
I am surprised to see that my pal Eric Gisse
is ignorant of the fact that atomic clocks DO NOT drift
"in tens of nanoseconds per day. "
What confuses my pal is that
what Galileo discovered centuries ago,
is that oscillators are affected by acceleration,
and that if one wants to have an oscillator
oscillate at the same rate in a different place,
one has to take the differences in accelerations
of the places into account.
The fact of the matter is
that the short term and long term drifts
of all of the oscillators used in the GPS system
is about the same.
It is interesting to see that although I have challenged
all of the General Relativity Cultists for years
to explain why it is desirable
BUT NOT ESSENTIAL
to have the oscillators in orbit
oscillate at the same rate as the
master oscillator on the ground,
NONE of the cultists seem to understand
why this is desirable.
All they do is just parrot their favorite
General Relativity Guru,
who is on the taxpayer dole.
One would think that if these Gurus and Cultists
were privity to powerful, esoteric knowledge
that they would use it to get off the tax payer dole
and make a few million bucks in the few market.
I am pleased to see that my pal Gisse,
wants to know how the GPS system works.

What you need is this, Tom:
http://www.androcles01.pwp.blueyonder.co.uk/GPS/GPS.htm
Sure they do. Some gain, some lose. Where the bigot Goose goes wrong
is in thinking his religion has something to do with it and can convince
someone else of his stupidity. GPS is accurate to 90 feet, uncorrected.
Modern combine harvesters are accurate to an inch using differential GPS.
That's quite simple, a local receiver obtains its GPS position and transmits
the difference between that and its actual position. The moving receiver
then adds its GPS position to the offset it obtains from the fixed local
receiver and thus knows its position exactly.
Where's “ up ” ? How fast is your clock ticking here vs. there ?
Einstein's General Relativity, your favorite topic,
answers these questions in fine detail.
Newton didn't know: “ c = 1, Energy = Mass ”.

a) Explain how acceleration affects an atomic clock.
b) Clocks in orbit are in free-fall and experience no such
acceleration.

Potter hates fundamental & basic research. He'd be the kind of person
arguing against the British research into sonar, pre-WW1.
I was surprised to see that Sam Wormley
did not know that:
"Light travels at a constant speed
of 299 792.458 meters per second
in the absence of matter,

and was disappointed to see that he snipped
the rest of my post that negates his strawman
such as:
"There is some variation in the time it takes the
signal to reach the receiver due to multi paths
taken by the radio wave to the GPS receiver,
so GPS receivers are programmed to compute out the
multi-path variations.."
It is interesting to see that Eric Gisse
does not know that "g" changes with altitude,
and that "g" is acceleration.
g = G * m/r^2
I suggest that my pal Gisse visit:
http://en.wikipedia.org/wiki/Gravity_(Earth)
If Gisse wants to know how much "g" affects
the oscillators on the GPS satellites,
I suggest that he read one of the many posts
that hanson has made about this.
When your level of argument cannot surpass the 'physics for liberal
arts' level of detail, you should know that you do not know what you
are talking about.
The period of a crystal oscillator or an atomic clock is not a
function of acceleration - JUST PENDULUM CLOCKS. Get it right or don't
talk.

if Poter clames that GPS has nothing to do with
curved space time

Gisse is a school boy from the Great Frozen North,
and does not yet know that people use the phrase
"relativity effects" from ignorance,
or to generically mean the
affects of acceleration and velocity.
What rational, intelligent system engineers do
is design closed loop system that adjust for
all effects including the DOPPLER EFFECT,
and the GALILEO EFFECT.
If the school boy read and understood my post,
he could see that it is not necessary to
get involved with tensors, worm holes,
rubber clocks and rulers, etc.
I assume that the boy understands the Doppler Effect,
and if he reads one of the many posts by hanson
about how acceleration is compensated for
by considering the Galileo Effect,
he might understand that.
The problem is that young boys
and people with inferiority complexes,
like to think they are privy to powerful, esoteric knowledge
as it makes them feel adequate.
And of course, Rabbis, Preachers, and people on the public dole
take advantage of this weakness in people.
to develop cult followings.
In what ways have "Einsteins contributions"
"had a big impact on our understanding of nature"
and demonstrate that these contributions
were not actually contributions of others.
Note for example, that I pointed out that
Einstein's General Relativity "contribution"
was a ripoff of Cauchy's stress principle
which asserts that when a continuum body is acted

Anyone who uses the taxpayer's money
to do research should justify the cost of the research
based on it asserted returns to the taxpayers,
and not waste the taxpayer's money on things
beyond man's capacity to ever experience
in time and space.
Can you imagine wasting the taxpayer's money
on such things as the beginning and end of the universe,
the mind of God, water witching, mind reading,
or even communicating with LGM's
if it cannot be justified in terms of
probability and return on investment?
It is easy to send other people's money
on your own fantasies.
If, as you claim, Einstein's General Relativity is a waste of time,
then you should be dwelling on other, more fruitful, activities.
As it stands now, I see you spending most of your time
pondering General Relativity, like a fat-man ponders food.

And that's what the designers did, which includes general relativity.
Which is why the GR correction is written in the GPS technical
specifications.
You should know that there is no such thing as the 'Galileo effect'.
That's just something you made up.
[snip pointless discourse]
As I indicated Eric,
"General Relativity" is a generic buzz word
generally used to indicate composite effects
such as the Doppler Effect, and the effect of acceleration
of an oscillating system discovered by Galileo hundreds
of years ago.
England sent ships all over the world with
standard pendulums (Oscillating systems)
and Newton used the data collected by this project
to compute the shape of the Earth, the mass of the Moon,
and tides all over the world.
Trust me on this Eric.
The GPS System does not operated open loop
based on General Relativity with 13 Classical Physics hacks.
It is a closed loop system that takes all possible
factors into account and compensates for them
as much as possible.
No doubt General Relativity is the model of choice
if you want to design a time travel machine,
create a worm hole, or warp space,
or speculate about the beginning and end of the universe,
and the mind of God, but it is not too useful for
real world applications in spaces occupied by
sentient beings, or for that matter living
plants and animals.

There you go again, Potter. General relativity is very fruitful
theory invented by Albert Einstein which describes gravitational
forces in terms of the curvature in space caused by the presence
of mass.
Web 2.0 is a generic buzz word. General relativity has a specific
meaning because its a goddamn physical theory with specific
predictions for specific conditions.

I would like you to not only document one instance of GR being used as
a catchall to include Doppler, but one peer-reviewed publication that
shows how acceleration affects an atomic clock.
Or do I actually have to tell you that GPS doesn't use pendulum
clocks? Because pendulum, water, and other weight-based clocks are the
only clocks whose period depends on acceleration.

It incorporates GR, read the spec. God knows I've personally cited it

As for your '13 hacks', well that's just more shit you made up. You
ranted about those hacks for years but myseriously stopped talking
about them when you realized you couldn't even fucking tell me what

Since you have personally said a few more things that are clearly

This is a blatant lie. As a multi-year super-senior, if you don’t
know, just keep your mouth shut. With al receivers doing acquisitions
of at least 4 satellites, GR correction is not needed. Just check
with the GPS manufacturers, and stop f*ckin’ spreading lies.

This should be a no-brainer. GPS requires a special frame of
reference to work which is right at the center of the earth. This
proves the principle of relativity wrong. Since the Galilean and the
Lorentz transforms both satisfy the obsolete principle of relativity
discovered more than 400 years ago by Galileo, GPS does not endorse
the ‘Galileo effect’. <shrug>

Snipping stuff you don’t understand explains why you still remain a
multi-year super-senior today at the very prestigious University of
Alaska. <shrug>
Hey, as long as Mommy is paying for all the bills, who give s a f*ck?
General relativity is totally based on the nonsense of mathematics
involved. You don’t understand the mathematics, and that is fine.
You don’t have to believe in the Wizard of Oz. <shrug>
The curvature of space was first conceived Gauss. It was his student
Riemann who was able to explain mathematically what curved space
really meant. The curvature in spacetime was first played around by
the Goettingen group of mathematicians including Klein, Hilbert,
Minkowski, and Schwarzschild. Notes that the curvature in spacetime
in 4-dimensions is merely an extension to the curvature in space of 3
dimensions already characterized by Riemann and Christoffel.
Mathematically, it is no big deal to add one more dimension to the
equations. The field equations can only be derived with the Lagangian
Hilbet pulled out of his very own *ss. The while episode is totally
nonsense in which Einstein offered no contributions. Your messiah
Einstein was merely a nitwit, a plagiarist, and a liar. <shrug> You
need to get over with that. <shrug>
So when the GPS specifications discuss the relativistic
corrections....they are lying? Or are you being stubborn?

Of course the GR correction is not needed as far as the receivers are
concerned, as the correction is applied within the transmitter
hardware itself.
Do explain why the GPS receiver manufacturers are relevant to this
discussion when the corrections aren't performed there.

Eric Gisse's preoccupation with what some spec writer wrote,
rather than simply examining how the GPS System
actually works, reminds me of the
navigator in the book "No time for Sergeants".
The navigator kept insisting they were over
the Gulf of Mexico, and telling the pilot
"Look at my charts!"
while the pilot kept pointing out
they were flying over a large city.
It is impossible to lead Eric through an explanation
of how the GPS System works,
because his mind is controlled by his
desire to have General Relativity play an essential role,
by what some spec writer wrote,
and by what some guy on the taxpayer dole wrote.
I used to read and write specs myself,
and come into contact with many spec writers,
and the people who told them what to write,
and I am very familiar with how specs are written.
Hopefully Eric will show where the specs spell out
the General Relativity algorithm used in the system.
If General Relativity is essential and is used,
how is the algorithm expressed in the programming
of the master station, the birds, and GPS receivers?
The spec writer could just as easily written
the Doppler and Galileo Effects are compensated for,
but what sounds better in this day and age?
And of course, a closed loop system compensates
for many effects, temperature, velocity effects, acceleration
effects,
pressure, drift due to aging of components, etc.
I, for one, am still anxiously awaiting for the General Relativity
Guru's
to design a time travel machine, a worm hole generator,
or a space warp rocket ship.
Or maybe design a machine, a bridge, a chemical compound,
a DNA sequence, a refrigerator, etc.
Let me ask you a simple question...
How do you know how the global position system was designed and built
since you had no part in the process and refuse to read the published
specifications?
The difference between you and me Gisse,
is that I analyze how things HAVE TO WORK,
and you believe what is written in some book,
on some paper, told to you by someone in authority,
told to you by mass media, etc.
That's why you are good cult material,
and I am an independent, creative thinker
who has helped many people in science and industry
solve problems.
That didn't answer the question. Read the question, and try again.

The only requirement is to allow all satellites to synchronize with

correction on board the satellites?

With the economic conditions like these we are facing, don’t you think
you should give your mommy some break?
Why is it a part of the GPS spec? Or do you take the added step of
arguing it isn't in the spec even after having the relevant parts of
the spec quoted from multiple sources?

Read the rest of the sentence. The correction isn't applied in the

Why ask questions whose answers you already know? The correction is in
the de-tuning of the clock so that the correct frequency is observed
on the Earth's surface.

Oh, yes. You are still stuck in the belief that relativistic effect
is required in the GPS design. At least, the multi-year super-senor
has capitulated. He now agreed that there is no relativistic effect
needed in the design of the receiver. Well, you need to argue with
that multi-year super-senior still without any college degree first.

The speed of light is approximately one foot per nanosecond, and the
timing delays from ignoring GR amounts to some 50ns/day. What kind of
position error would be accumulated after a week?
Try to not take cracks about my engineering ability when you willfully
ignore critical pieces of the GPS specifications.
When you were an engineer...did you ignore the spec when building
things? Alternatively, what would you say if people responsible for
building what you helped design willfully ignored the specifications
you wrote? Think about it.

Belief systems are not a factor. Physical reality--for an observer on

In GPS, relativistic correction is not need at all. Just what denying
on what do you have?
If what Sam says is true,
the GPS receivers of "observers on the earth"
must have 13 General Relativity algorithms in their receivers,
to compensate for the 13 hacks of General Relativity
required to make the GPS System work.
Those little battery operated computer chips
must be very powerful to
compute all 13 hacks of General Relativity every second or so,
or else the algorithms used must be pretty simple.
In either case, I am sure the General Relativity Guru's and Cultist's
know what they are and will tell us.
As Dork Moortel is not only a General Relativity genius,
and a math genius, he is also a computer genius
so no doubt he will be able to post the algorithms in
one of the computer languages to prove to folks
that General Relativity is really useful,
and is essential to the GPS System.
Dork's son is also a genius
who knows more physics than anyone in sci.physics,
except Dork himself of course,
and maybe if Dork does not have time
from the unemployment line,
he'll have his son post some of the algorithms.

Gisse, why don't you do as I do,

so that you will know what 13 Classical Physics hacks are needed
to get GPS data to agree with General Relativity.
I'll give you a hint,
the Hubble, Galileo, and Doppler effects
must be accounted for,
as well as the magnetic and electric effects,
the lumpiness of the Earth, static friction,
dynamic friction, variations in the ionosphere,
atmospheric pressure and humidity, etc.

The trouble is, Tom, that you didn't read my references and you
don't have the foggiest idea what the twelve relativistic corrections
are and why some are space based and why one is in receiver algorithms.

The lumpiness manifests in multipole moments that need to be taken
into account when modeling Earth's gravitational field.
It looks like the physicists are still playing in the sand box
worrying about non-existent issues in a schizophrenic fashion. In the
meantime, the engineers are carrying this GPS technology ahead.
Get a grip, Sam. The first GPS proposal called out for an acquisition
of 3 satellites. In this case, there is indeed a need to synchronize
the ground and the satellite clocks. However, engineers seem to be a
lot more clever than physicists time after time. The engineers had
found a way in acquisition of 4 satellites. In this case, there is no
need for GR anymore.

Sam, it is also OK for you not to understand the mechanism in
acquisition of 4 satellites instead of just 3. <shrug>
GR is in the spec whether you accept it or not.
GPS works whether you believe in GR or not.
Reality doesn't care about you.

Show me the spec that is if you recognize a spec. The write-ups by
these schizophrenic physicists do not count as a spec in case if you
“dono”.

That is correct. There is no need for GR nonsense in GPS. <shrug>
> Reality doesn't care about you.
That is also very correct. GPS continues to function without
pollution from GR. <shrug>

More cowardly excuses from a multi-year super-senior. <shrug> What
time did you wake up this afternoon?

The same cite I have been citing you for god knows how long now.
You don't get to ignore the spec just because you hallucinate that
physicists wrote it and that you hate physicists.
Sammy, I suspect that you don't have the academic or
intellectual capability to work through the material and gain insight
about how the GPS System actually works,
because you are more interested in attracting folks to your
phony "EDU" web site, and accumulate Google sense hits,
and in trying to con folks into thinking
that you are a General Relativity and GPS Guru,
and are privy to powerful esoteric knowledge.
Now Sammy, if you really have the
academic and intellectual capability to express yourself,
and you understand tensors and General Relativity,
why don't you prove it by computing just ONE
of the many tides that Newton computed hundreds of
years ago, using his primitive model, and hand calculation.
Sammy, your attitude appears to be,
"I can't understand this shit, (General Relativity and GPS)
so therefore I will attack the messenger
in order to avoid looking like a phony asshole."
I am pleased to see that my pal "doug"
got my message that General Relativity is
not capable of modeling the GPS System,
and that is necessary to
operate the GPS System CLOSED LOOP
use other models to account for many effects,
in order for the GPS Syatem to operate successfully.
I was disappointed to see that my pal "doug"
did not know about that "air friction"
occurs whenever an object is moving through a gas
and is a function of the speed of an object and it's geometry.
Perhaps my pal does not know
that there are are gas particles in the GPS orbit,
and that this introduces effects that must be corrected for.

Nothing wrong with google groups, it is outlook express which has

Potter, you'vr been corrected on this point before.
GPS is not a "Closed Loop" system.
Please read the specs:

That is no spec. It is merely a lousy application note, you ignorant
multi-year super senior. That must be written by a physicist or an
ignorant engineer. <shrug>
In the meantime, GPS continues to function without any pollution from
GR. <shrug>
Since you have also accepted that there is no need for GR correction
in the GPS receiver, how do you reconcile with Wormley and Professors
Ashby’s and Taylor’s nonsense of 38uSec crap?

The GPS designers say otherwise. You are clueless.

It isn't in the receiver, fucking moron. How stupid are you?

It looks like our multi-year super-senior is utterly confused. He
possesses no intellectual reasoning to tell what is bullsh*t and what
is not. In doing so, he chooses to accept the academics as faith
while the engineering world is telling him otherwise.
You have capitulated on GR having nothing to do with the receivers.
Yes, it only takes some rudimentary understanding of algebra to do
so. Yet, the academic power houses like Professors Ashby and Taylor
are telling you otherwise.
The darkside of science is not worth the fame and the grants. With
the depressed economy going forward, I predict these so-called
physicists are going to turn on their crackpot thinkings to a zenith
to compete with their pears (excuse me, peers).

bigger grants. <shrug>

You are utterly incoherent now. Go back to be a multi-year super-
senior sponging off mommy. I hope she is wealthy. <shrug>
No, they aren't. They are saying the effect is accounted for in the
GPS sattelite itself. Which is what people have been telling you for
years now, and I guess you still don't get it.
Relativity has been confirmed to high accuracy over time periods of
many days. New corrections for epoch offset and rate for each clock
are determined anew typically once each day in the GPS Systems, These
corrections differ by a few ns and a few ns/day, respectively, from
similar corrections for other days in the same week. At much later
times, unpredictable errors in the clocks build up with time squared,
so comparisons with predictions become increasingly uncertain unless
these empirical corrections are used. But within each day, the clock
corrections remain stable to within about 1 ns in epoch and 1 ns/day
in rate.
So if these GPS Systems are in geosynchronous orbit with our earths
rotation it makes since that the further away from the center of our
core more distance is covered as they travel trough longer periods of
gravations because of circular orbit is larger than the rotational
orbit of a clock closer to the center of where our gravity feild
originates it's logical that Contributions from altitude
synchronization prescription are intimately connected.
but what if the clocks on the satellites were made to travel the same
rotational distance around the earths rotation by lagging the orbit so
the same distance was traveled through the gravations I suggest that
it's not so much the altitude but the distance traveled longitudal
relative to both clocks orbit around the center of our gravity feild,
not altitude, with altitude longitudinal distance increases away from
the center of a rotating spheroid’s, the difference in this distance
around the orbit between the two clocks that cause clock malfunction.
more distance is covered in geosynchronous orbit so a clock closer to
the gravity center of a rotational sphere has less gravitational drag
almost like saying gravity must have resistance.
