Need? Could you still make GPS system if there were not relativistic effects? Sure.
But these effects are there, and you need to needs to make allowances for it. This is due to the difference of the passing of time in a semi-synchronous orbit compared to where the receiver is, and for the journey between the two. The calculations needed for approximating the required correction can be found on page 88 of https://www.gps.gov/technical/icwg/IS-GPS-200D.pdf.

(1) GPS duznt use any STR or GTR corrections.
(2) The ticking of the clocks are certainly affected by speed & elevation & location, in relativistic ways.
(3) There is no difference of the passing of time, koz time duznt exist, there is no such thing as time dilation.
(4) Yes, there is a need to make allowances for the differences in ticking rates.
(5) No, they don’t use any STR or GTR equations, ie to pre-set the ticking rates, or to adjust the ticking rates, or to adjust the indicated times.
(6) They use equations that they know work, that have been proven to work.
(7) In any case they make regular adjustments during each day, no drastic action needed.
(8 ) The adjustments mentioned in (5)(6)(7) are not necessary, but the GPS system works more easily if the clocks tick as closely as possible, rather than the operators having to juggle huge numbers.
(9) GPS falsifies STR, & to some extent falsifies GTR. Koz STR says that time dilation is reciprocal, but GPS shows that it aint reciprocal, STR is a dead-duck.
(10) Einsteinists try to wave away the GPS falsification of STR by inventing & invoking an orbital Sagnac effect. They always seem to be able to invent something to get around any kind of failure, & it duznt matter that it makes no real sense, as long as it satisfies disciples, & anyone who believes in STR is easily satisfied.
(11) There is no excuse for not knowing most of the above, anyone can google the views of GPS experts.

I've shown you how it gets used. You can stick your fingers in your ears and go 'lalalala no it doesn't.' And Steinmetz laughs at you.
--- Quote ---Anyhow, i am still waiting for u to explain to me how STR can help B' to make an mmf (ie having already used STR to make an mmf from B). No hurry.

Your entire understanding of the phenomena is shoddy 'krapp' so you wouldn't even understand any such answer (if the foundation of your question wasn't even on already super faulty premises). You can't even read the equations.
Let's not forget how little you admit to knowing,

Translation:
"Herp dee derp, I don't even know the first thing about relativity."
And you want to get all worked up about relativistic transformations of the E-field in current carrying wires - and you don't even know what a high school AP physics student knows about electrons and special relativity.
This material is too advanced for you. Go back to secondary school. :scared:

Voigt was the first to derive an equation for gamma. But i think it was Searle that was the first to derive a transformation for em radiation. Not for wires, but for em radiation, in connection with length contraction. I think that Lorentz built on that. I think that Larmor used his own transforms to derive equations for gamma for the ticking of atoms. But he didn’t call this time dilation, he wasn’t that stupid. Neither was Lorentz.
But along came Albert, & he was stupid, & he foisted time dilation on the world, & the rest is history.
Anyhow, length contraction is often quite rightly called FitzGerald length contraction.
And ticking dilation is often quite rightly called Larmor ticking dilation. However, this can only apply to atomic clocks, it seems to be fairly accurate re atomic clocks, but its main problem being that it duznt readily explain the change in ticking with elevation. But in any case the Larmor gamma can't be applied to any other kind of clock.
Einstein's STR is based on relative velocity, or in the case of his time dilation it is based on relative speed.
All of the other kinds of relativity are based on the speed of the object through a static aether.
The neoLorentz version is based on the aetherwind blowing through the object or clock.
My own version of relativity is i think the best. The length contraction part is based on neoLorentz. The ticking dilation part is based on a combination of the length contraction due to the aetherwind plus a GTR kind of contribution to the length contraction due to the nearness of mass. All ticking dilation being due to length contraction. With each kind of clock being affected in a different way (eg balance wheel clocks, pendulums etc). I have made an Excel for the ticking dilation of tuning forks.
Bearing in mind that length contraction has never been proven. What i mean is that there is definitely a change in length or in width or some combination, but we don’t know which. I think that Lorentz mentioned this.
The funny thing is that in the modern era the only tests of time dilation have been by using atomic clocks, which were only invented after Einstein died. Einstein loved balance wheel clocks, but (i know that) his time dilation gamma can't possibly apply to balance wheel clocks (but might be ok for atomic clocks)(we don’t know yet).

Sounds like a toned down version of Time cube.

But the reference to the effect of the gap on the speed of electrons must be a typing error. U must have meant electons. It is old (electron) electricity that can't explain (how insulation affects the old (electron) electricity speed)(or how a small gap might affect).
But in any case we can't say can't based merely on a gedanken, we would need real numbers/speeds.

So all electronic devices designed, manufactured, and tested according to old-electrons that show no discrepancies to classical theory isn't enough to go by? It all works according to the classical theory, it's all explained in a cohesive set of equations that agree even with broader observations of the universe.
Electons don't exist in classical theory, so it would be surprising if I felt a need to reference them, but yeah, could easily be a typing error or a sign of mental deficiency, it's difficult to be sure. But we sure do need some real numbers and speeds, when can we expect some quantitative predictions regarding electricity and magnetism to test your theory?

Elektons were discovered/invented in Dec 2021 to better explain what we see re electricity, ie better than the drifting electrons nonsense.
If u can show me one instance where elekton elekticity duznt work, or works less well than drifting electrons electricity, then u win.
The best test that i can think of (of my new (elekton) elekticity) is a measurement of the speed of elekticity along a threaded rod compared to a plain rod. The speed of elekticity along the threaded rod will be slower in the ratio of the extra distance up&down over the threads.
But i like your idea that we should abandon all electric devices designed before my new (elekton) elekticity was discovered in Dec 2021.
They should have abandoned devices designed before STR in 1905. Bad luck for Steinmetz.
They should have abandoned devices designed before the electron was found in 1897.
They should have abandoned devices designed before the electron was named in 1891.
They should have abandoned devices designed before the charged particle was hypothesised in 1838.
They should have abandoned all devices designed by Tesla, koz before 1905 he hadnt heard of STR, & after 1905 he didn’t believe in STR.
Wow, this is going to be a big job. I wonder whether i should have kept quiet.

…………….. Interactions involving electrons with other subatomic particles are of interest in fields such as chemistry and nuclear physics. The Coulomb force interaction between the positive protons within atomic nuclei and the negative electrons without, allows the composition of the two known as atoms. Ionization or differences in the proportions of negative electrons versus positive nuclei changes the binding energy of an atomic system. The exchange or sharing of the electrons between two or more atoms is the main cause of chemical bonding.[13] In 1838, British natural philosopher Richard Laming first hypothesized the concept of an indivisible quantity of electric charge to explain the chemical properties of atoms.[3] Irish physicist George Johnstone Stoney named this charge 'electron' in 1891, and J. J. Thomson and his team of British physicists identified it as a particle in 1897 during the cathode-ray tube experiment.[5] Electrons can also participate in nuclear reactions, such as nucleosynthesis in stars, where they are known as beta particles. Electrons can be created through beta decay of radioactive isotopes and in high-energy collisions, for instance when cosmic rays enter the atmosphere. The antiparticle of the electron is called the positron; it is identical to the electron except that it carries electrical charge of the opposite sign. When an electron collides with a positron, both particles can be annihilated, producing gamma ray photons…………..
When Einsteinists finally agree whether relativistic mass exists (ie that mass increases with velocity), & when they finally agree whether the concepts of longitudinal mass & transverse mass exist (for a beam of electrons in a CRT), then which Cathode Ray devices should we dump at the dump. Could we sue the manufacturers of TVs?
