>GPS needs real-time accuracy. It wouldn't work on an accumulating error that keeps getting reset
You can reset it at any rate you want, 1000 times per second if you want, all you have to do is the rate at which the rate of time distortion

>How do you know how much to reset it by?
Basic experience will tell you it depends on two parameters, speed and height of the satellite, but really only 1 parameter since height and speed are correlated. It would be obvious that for any satellite at a circular orbit there would be a fixed daily delay. So say its 1 second a day, one day the clock would say 2:59:59 when its supposed to be 3:00 pm, one more day it will be 2:59:58 instead of 3:00 pm, and so on.
You can easily find an empirical formula for the delay as it depends on a single parameter, delay vs height, at least for circular orbits which are exactly the orbits for GPS satellites.
Or even easier, since circular GEOSYNCHRONOUS orbits have a single fixed height, you just have to fund the delay for a single condition, a single height and speed, so you dont need a formula for a general case.
Its about 40 microseconds per day, you can just change the settings on software to adjust it, if 40 microseconds dont work, try 41 or 39 until you get no delay.
Like developing a calendar system before understanding orbital mechanics, if you say the year is 365 days with enough time seasons wont fall on the same months and you know you have to change the calendar

>Okay but you said GPS wouldn't work, which is false.
>The only thing "adjusting for relativity" would help with is keeping accurate time
The "only" thing, lol. Thats the whole point.

>and how do you suppose we sync them without relativity?
By mutually comparing their clocks

Folding space is impossible it's pure science fiction the people that come up with this shit are just trying to stay employed so they don't have to get a real job

The only way to get to other solar systems is generation ships that will take thousands of years and there will basically be no benefit to doing this unless our sun is dying

And how do you compare clocks? You receive a signal from each and compare your "reference time" (could be one of the clocks) and adjust for the time it took the signal to traverse the distance between the clock and the receiver. This is literally special relativity 101.

>And? Yes, you can compare clocks. Its possible. What is the point you are trying to make?
If you are unable to comprehend the notion that you need a signal traveling at a finite speed to sync clocks, which influences the syncing procedure itself, then you're too much of a brainlet to argue about relativity. Simple as.
>Are you even aware that all satellites in geosynchronous orbit have the same orbital parameters anyway, same speed and height, and have identical time distortion?
Ideally they would be. No orbit is perfectly circular as there exist perturbations due to e.g. oblateness of the Earth and gravitational pull from the Moon. Circular orbits have zero measure in phase space and thus any tiniest increment in orbital parameters makes them elliptic. Which is why the GPS clocks need to be synced with each other by continuously sending signals and self-correcting as their orbits aren't in perfect alignment.

kek you need a protocol to sync your clocks. If you are using atomic clocks over distances several times the diameter of the Earth, the finitude of the speed of light becomes a factor.

Hang on, are you saying that if you blasted someone out into space, and it was possible to just circumnavigate earth for a while and come back to earth a year later their watches/clocks would be wrong I.e different (assuming the hour got adjusted at the same point for summer/autumn) changes?

Yes, although only atomic clocks have enough precision to measure this. Time isn't universal.

>So what? What does that have to do with relativity?
I should elaborate as the GPS system relies on both special and general relativity
>special relativity
The speed of light is the same for all observers and is finite. So in order to sync your clocks, you need to know how far apart they are and correct for this.
>general relativity
The Schwarzschild solution introduces yet another perturbation to the perfect Keplerian orbits generated by Newton's inverse square law (in addition to oblateness of the Earth, pull from the Moon, etc) which influences the relative distances between satellites and thus the syncing procedure as I explained above.
>Common clocks lose accuracy on their own due to myriad of reasons
And you need to account for this too. GR isn't the only thing the GPS system needs to correct for, but it is so precise that it does need to account even for tiny effects of GR IN ADDITION to other perturbations.
>If you literally try to adjust satellite clocks based on some theory, you will get it wrong, because theres multiple unknown sources of error, not just time dilation.
They're all accounted for, otherwise the system just wouldn't work in the first place.
>You have to actively measure the error to correct it, not to guess it from a formula.
And how do you correct it without a theory (or a protocol) telling you what to do? This is some engineer tier logic. Imagine running a nuclear reactor and just going
>frick all those theorists, we're just gonna eyeball it as we go

>You keep refusing to explain the actual mechanics of the time comparison
I literally did
>You just measure and correct it, its not a calculation, its a measurement.
There are measurements and calculations; errors quantify the difference between them. How the frick do you "correct for error" if you don't know what the measurement is supposed to be without a theory? What are you correcting for then? Have you ever, in your life, done a science lab? Holy shit, what a brainlet.

>You have not explained any protocol for comparing clocks.
I did. Read

And how do you compare clocks? You receive a signal from each and compare your "reference time" (could be one of the clocks) and adjust for the time it took the signal to traverse the distance between the clock and the receiver. This is literally special relativity 101.

. You don't need the theory of relativity to know that the speed of light is finite and is the same for all observers. Both are experimental facts and you can measure them, both were measured before Einstein and are the reason he came up with the theory in the first place.

You don't need to know the theory relativity to understand how syncing two separate clocks requires you to receive a signal from both. You don't need to know relativity to understand that the signal taking some finite time to reach you needs to be accounted for when you sync the clocks, because there is a time difference between the time readout you receive and the concurrent time of the clock you're trying to sync. You just need a brain. Sorry you don't have one.

Here's an example if you're really struggling with "abstractions"
>clock in its own frame reads 10:35 and sends this information to an observer
>it takes the signal one minute to reach the observer
>the observer receives "10:35," but by that time the clock is already at 10:36
>to account for this "error," the observer needs to his distance to the clock and how fast the signal is traveling
here is your protocol

>What observer?
You, me, the guy syncing the clock, whatever the fed facility responsible for running the GPS system, you name it
>Whos measuring this "minute"?
the observer
>You talk about "a clock", what clock?
Any device that measures time.
>"the observer need to his distance", this isnt even english.
Didn't proofread on an anonymous Congolese whale hunting forum
>What you just described isnt a protocol for anything. Write something rational and operative without such gaping holes
Eat a dick, homie.

Jesus Christ, here’s my last (You). I don’t know why I tend to effortpost when responding to utter morons.
