Real-World Relativity: The GPS Navigation System

People often ask me "What good is Relativity?" It is a commonplace to think of Relativity as an abstract and highly arcane mathematical theory that has no consequences for everyday life. This is in fact far from the truth.

Consider for a moment that when you are riding in a commercial airliner, the pilot and crew are navigating to your destination with the aid of the Global Positioning System (GPS). Further, many luxury cars now come with built-in navigation systems that include GPS receivers with digital maps, and you can purchase hand-held GPS navigation units that will give you your position on the Earth (latitude, longitude, and altitude) to an accuracy of 5 to 10 meters that weigh only a few ounces and cost around $100.

GPS was developed by the United States Department of Defense to provide a satellite-based navigation system for the U.S. military. It was later put under joint DoD and Department of Transportation control to provide for both military and civilian navigation uses.

The current GPS configuration consists of a network of 24 satellites in high orbits around the Earth. Each satellite in the GPS constellation orbits at an altitude of about 20,000 km from the ground, and has an orbital speed of about 14,000 km/hour (the orbital period is roughly 12 hours - contrary to popular belief, GPS satellites are not in geosynchronous or geostationary orbits). The satellite orbits are distributed so that at least 4 satellites are always visible from any point on the Earth at any given instant (with up to 12 visible at one time). Each satellite carries with it an atomic clock that "ticks" with an accuracy of 1 nanosecond (1 billionth of a second). A GPS receiver in an airplane determines its current position and heading by comparing the time signals it receives from a number of the GPS satellites (usually 6 to 12) and trilaterating on the known positions of each satellite[1]. The precision achieved is remarkable: even a simple hand-held GPS receiver can determine your absolute position on the surface of the Earth to within 5 to 10 meters in only a few seconds (with differential techiques that compare two nearby receivers, precisions of order centimeters or millimeters in relative position are often obtained in under an hour or so). A GPS receiver in a car can give accurate readings of position, speed, and heading in real-time!

To achieve this level of precision, the clock ticks from the GPS satellites must be known to an accuracy of 20-30 nanoseconds. However, because the satellites are constantly moving relative to observers on the Earth, effects predicted by the Special and General theories of Relativity must be taken into account to achieve the desired 20-30 nanosecond accuracy.

Because an observer on the ground sees the satellites in motion relative to them, Special Relativity predicts that we should see their clocks ticking more slowly (see the Special Relativity lecture). Special Relativity predicts that the on-board atomic clocks on the satellites should fall behind clocks on the ground by about 7 microseconds per day because of the slower ticking rate due to the time dilation effect of their relative motion.

Further, the satellites are in orbits high above the Earth, where the curvature of spacetime due to the Earth's mass is less than it is at the Earth's surface. A prediction of General Relativity is that clocks closer to a massive object will seem to tick more slowly than those located further away (see the Black Holes lecture). As such, when viewed from the surface of the Earth, the clocks on the satellites appear to be ticking faster than identical clocks on the ground. A calculation using General Relativity predicts that the clocks in each GPS satellite should get ahead of ground-based clocks by 45 microseconds per day.

The combination of these two relativitic effects means that the clocks on-board each satellite should tick faster than identical clocks on the ground by about 38 microseconds per day (45-7=38)! This sounds small, but the high-precision required of the GPS system requires nanosecond accuracy, and 38 microseconds is 38,000 nanoseconds. If these effects were not properly taken into account, a navigational fix based on the GPS constellation would be false after only 2 minutes, and errors in global positions would continue to accumulate at a rate of about 10 kilometers each day! The whole system would be utterly worthless for navigation in a very short time. This kind of accumulated error is akin to measuring my location while standing on my front porch in Columbus, Ohio one day, and then making the same measurement a week later and having my GPS receiver tell me that my porch and I are currently about 5000 meters in the air somewhere over Detroit.

The engineers who designed the GPS system included these relativistic effects when they designed and deployed the system. For example, to counteract the General Relativistic effect once on orbit, they slowed down the ticking frequency of the atomic clocks before they were launched so that once they were in their proper orbit stations their clocks would appear to tick at the correct rate as compared to the reference atomic clocks at the GPS ground stations. Further, each GPS receiver has built into it a microcomputer that (among other things) performs the necessary relativistic calculations when determining the user's location.

Relativity is not just some abstract mathematical theory: understanding it is absolutely essential for our global navigation system to work properly!

So you still refusing to tell us why you have been banned so many times?
Is Dywyddyr correct saying it was "delusional arrogance"?
If that's the case, in light of the evidence and examples I have just given, our mods here also have an open and shut case to ban you for the same reasons....delusional arrogance.

And I would suggest that along with the questionable qualities of delusion, arrogance and trolling ability, we could also legitimately claim you are a conspiracy adherent too.
I mean you do believe that the world's accredited professional cosmologists and scientists in general, are all ganging up on you and trying to prevent you from enlightening the world to your "enlightenment"
So what other conspiracies do you adhere to?
You have many questions to answer, but I really don't expect any answers at all, just the usual childish claims about "your proof" and your "experiments" and your expert unwavering certainty.
And just like that which Bozo the Clown attracts, the forum is awash with laughter at you.

If you find science insane, then best stick with more "sane" pursuits like astrology.

If all particles in the universe stopped their motion, then yes - time would effectively stop. If they then restarted, time would restart.

And I posted the correct equation - t = t0/(1-v2/c2)1/2. Can you dispute that?

All though you do not have authority to ask me questions of this nature, or are not one of these professional cosmologists you claim is replying to me, I will answer your questions.
Why did I keep getting banned from forums? My lack in the ability to communicate to a literate standard that could be understood, and the lacking in patience of forum members , like yourself, whom do not understand the notion of the literature content.
I have no arrogance, I do not think I am better than anyone, or have an entire data base of knowledge in my head, that I do have at my finger tips.
You are not asking questions about my paper notion. You and others are trying to impose a science discipline on me, sounding like a group of Joseph witnesses, and preaching back present information , probably all members , including young members , already know.
I expect strong opposition to my ideas, but I also expect the ideas to be self objective looked at, and if the idea can be destroyed for it's own merit, then fare play.
However, I do know your science, now my science as well, and my ideas are based around present science, and my ideas, I can not destroy with present knowledge.
I quote the last post ,''if all particles in the universe stopped their motion, then yes - time would effectively stop. If they then restarted, time would restart''.


I am being 100% honest when I tell you this, if the world and science truly believes the above post, that if all matter was in a stationary reference frame, with no motion of state, that time would stop, then OMG , I really am the smartest person on the planet, and I will sound arrogant in saying that is some dumb ass thinking.


That is like saying if a clock stands still , it will stop ticking. Even if the clock battery ran out, time does not care and carries on. This is seriously deluded thinking by science.

 

Can I dispute your maths, in all honestly no, I do not understand it. If you writ it out in full, then yes I may understand it.

 

Impressive words, but what exactly are you trying to show that relates to time dilation?

 

The time line is a constant at c, I am using this to measure time interactions within time. Can you please define your time dilation in this diagram of the GPS system?

 

deleted

 

I realize that in all likelyhood you have no interest in actually learning anything about the math or explanation of time dilation, but in the vanishingly small chance that you are interested here is an explanation.

Time dilation.

 

I really don't believe I have met or corresponded with anyone that has confused rather simple issues with their own weird take on the situation more then yourself.....
[1] No I don't have any authority, but I also believe all viewing your nonsense should know how ridiculous it is, and also how arrogantly and stupidly stubborn you are in refusing to accept all the evidence refuting your stance.
That of course is also highlighted in your even crazier "dark is real and light is an illusion fairy tale"
[2] The professional cosmologists I am referring to is the mainstream acceptance and the giants of the present and past which you so arrogantly ignore.

So you are a conspiracy adherent. The world is ganging up on you and refusing to accept your knowledge. Thanks for confirming that anyway.
But the far more likely reasons are as has already been claimed.....You totally ignore, misinterpret and lie about the accepted mainstream physics, then pretend to offer some non existent maths that supposedly supports your model, making it indisputable fact.
They are the reasons why you have been banned. Perhaps you would have more success on a religious forum, or one promoting Santa Claus and the Easter Bunny.

The overwhelming evidence of your time here and elsewhere tells a far more convincing story.

Ahaa! So that it. More delusions and conspiracy nonsense.
Your belief in everyone should be able to think for themselves, is taken to unreasonable, unfathomable depths of stupidity.
Yes its a requirement that any successful scientist must be able to think for themselves, as it is required also in everyday life.
But that thinking must also be tempered with the fact [1] when someone is obviously in error, he must accept it and move on [see Einstein] [2] Modern cosmology of the 20th/21st century has shown us that intuitive concepts we once accepted as "gospel" [as the absolute nature of space and time] do not hold when we enter territories of relativistic velocities, huge mass/densities, and vast distances coupled with the finite speed of light.
The Universe and the instruments our technology has given us, has shown us irrefutably, that time and space [henceforth known as spacetime] is not "absolute" and that time and space can be totally different in another FOR to what we perceive in our own FOR, while at the same time, all FOR's remain as valid as each other. This is one of the most proven concepts to arise from relativity and is beyond question. [3] Thinking for ones self must also entail the thinking of the giants of the present and past and the knowledge they have passed on to us....well most of us anyway, you seem to be ignoring that in your arrogant assumption, that what "you think should take pride of place" ignoring everything else.

You have strong opposition and total refutation to your ideas because [1] You have no evidence or correct maths to support your hypothesis, [2]You totally ignore all observational and experimental evidence supporting the accepted scientific explanation....eg: You claim time dilation does not happen, despite observational evidence that it does You claim that dark is real and light is not despite overwhelmingly observed reality that dictates otherwise.[3] You ignore as mentioned previously] and scoff at the giants of the past, in your fanatical desire to show your supposed independant ability to think for yourself, which you like to wear as some sort of "badge of honour" and that the rest of us should stand back in awe at that ability.

Again you show your dishonesty. First, I certainly do not believe that, and secondly you again misinterpret. I would say that the question of time stopping if all motion were to stop, is really a philosophical question, like a tree falling in the forest with nobody around to hear it.
If all motion were to stop, then time wouldn't, but it wouldn't much matter because know one is around to measure its flow.

Finally what I or anyone will tell you will certainly be to no avail, as has been shown elsewhere on other forums, and resulted in your banning.
Your warped way of thinking [and the reasons as I have given] and refusal to accept that you are 100% totally wrong not only blinkers your view of the world around you, but completely blinds you to it.
Sad.

The whole article. But therein lies your problem. You simply reject relativity and the postulates that arise from it and time dilation.

 

Because you're a dishonest deluded idiot with a messiah complex.

Apart from your your insistence that you're right and everyone else is wrong you mean?

1) This is demonstrably false.
2) It's not "our" science it's science. Something is either science or it's not.

You don't have any science.

Again, demonstrably false, given that you reject the results of "present science".

So much for someone who's just claimed to "understand our science".

Pffff, I can not explain my ideas in any more basic language and explanation than I have that a 6 year old would agree with. It is not me whom is wrong, and again I notice avoidance of questions, and only notice words of trollish nature.

''But that thinking must also be tempered with the fact [1] when someone is obviously in error, he must accept it and move on''.

Something I suggest science does all the day in the avoidance department of the truth.

I am not in error.

You are still not listening and indeed being apart of the science preacher society giving science a bad name, and a none self objective look.

''Because you're a dishonest deluded idiot with a messiah complex''.

Unbelievable arrogance, and trollish behaviour. In one sentence you slanderish say I am a lier, refer to me have having a mental disorder, say I am stupid, and compare to me to me thinking I am some god, when I am not religious, tell the truth, have a good IQ, and am a quite sane father of two.

Ok troll we get the picture now, you are a troll and play the good troll part.

However, you are messing and keep trying to get me banned, God troll for sure.

Ok , I will ignore the obvious God loving trolls, and their lame attempt to try to deny the obvious axiom truth , that I have tried and tested on members of the public, who agree with me, and do not agree with present science fact.


This is where I am now going to get mad at the trolls , and hit them where it hurts, and that is with the mind.

The speed of light , c, is a constant speed to all observers , science has to agree.

No matter where I am in the universe , my observation of light speed will always be measured at the same rate.


To record ''time'', at the present we use a Caesium atom and count the corresponding beats, Caesium-133 was chosen to be used in the definition of the second by the International System of Units. Since then, caesium has been widely used in atomic clocks.

The reason science uses a Caesium atom, is because the corresponding beats, are also a constant, x amount of emittance per second that does not vary in a stationary reference frame.

Experiment - We mimic the Keating experiment. Firstly we notice that the parameters of the experiment are different, a different altitude, different pressure, different gravity etc.

A conclusion I would make of what the results might be even before the experiment, I would expect some difference, as the comparison test was not a fare comparison test.

First error by science in their thinking.

Second error, This time I mimic the Keating experiment , except I have 100 observers, all placed throughout dimensions of space. However, my 100 observers, are not going to use the Caesium atom to count time, they are going to use the constant of the Sun's light. to time the said dilation of time.

Any one with half of brain understands this........and why science has it wrong.

 

constant versus t dilation diagram.

 

Ironically this fact means there must be time dilation.

 

To the contrary. It means that my time keeping method is a better, more accurate than the constant of the Caesium atom, that is changed by altering parameters of its existent state of being.
Ironically it shows the said called idiot of science, to be not such an idiot, and actually knows the reality of cosmology, and can clearly see that a visual Universe, is Physically proven to be only a part of a greater Universe.
Expansion of matter beyond our visual range, creating visual Universes beyond our means of travel and sight.
A boundary of distance and a boundary of sight limitations, created a multi-verse of visual spacial dimensions of time and space, observable Universes, by light.

A misconception that the big bang was the beginning, is the lack of ability to see beyond the boundaries.

And yet your positivism attitude will in the end be to know avail....Science will proceed based on observational evidence, the BB, SR and GR will continue each within their own regions of applicability, and you'll continue to be a fool in your delusions.
You are never going to make, and will never make any difference to the real knowledge, theories and discoveries.

 

An honest reply. Thank you. Once you can refute it this discussion may start to have a bit more meaning.

See earlier post where the variables are defined.

 

Clueless is certainly not on my part.

You are under such an illusion it is laughable.

I time an experiment using FPS, in this experiment we are going to use two clocks, one clock is static, and one clock is in the air in motion.

The clock on the ground is a constant at ten beats per second, the clock in the air is a constant at 10 beats a second but alters to 5 beats a second by timing dilation caused by gravity extraction of energy.

One clock 10 beats a second, one clock 5 beats a second, both are still a second. It would not matter if it were a 1000 beats different a second, it is still one second.

Using FPS, we can clearly see no difference, you are seriously all deluded, and yes I am now going to start being super arrogant for the simplicity of you are being arrogant and not bloody listening to anything except yourselves.
