Nonsense. Initially, self-styled physicists had laid out a system
that suggested relativistic correction if existed, but engineers had
outsmarted these idiots and came up with a system that does not
require relativistic correction if existed. shrug

Do not screw the history, it is quite the opposite.
The correction was not done initially,

Yes/no.

Read the last 3 links regarding NTS-2.

but later these smart engineers realized there is need to introduce
it.
It does not matter in what part on system it is done.

Yeah, it does. Unless you think its' practical to put an atomic clock in
every handheld device. That isn't even practical in 2011 much less in
the 1980's when the system was being designed and implemented.


In a more thorough analysis, any relativistic correction is basically
resetting a counter. It is merely a software solution and Mr. Wilson
had pointed out. You can fly with cheap oscillations driving your
chronological time if you can devise clever ways to synchronize all
the satellite chronological time. System similar to IEEE1588 or NTP
should easily suffice, and it is still a software solution. shrug

We do not need any analysis to tell you
time correction is just simple HW or SW based operation.

He's stupid. I don't mean ignorant, I don't mean 'aww he is trying so
hard', I mean he's as stupid as a rock and equally stubborn with the
disposition of a mule.

You'd be better off just telling him to **** off, and killfile.


One thing is how
other thing is why
and yet other thing is how much.

BTW NTP is far way innacurate to serve GPS needs.

He's a ****ing idiot to even suggest that. Network latency is literally
impossible to account for except on dedicated lines after much study.
This has been thought of plenty of times, and doesn't ****ing work. NOT
EVEN IN PRINCIPLE.

Maintaining synchronization on a LAN is only possible down to the
microsecond level without serious, serious work.

Dip**** supreme up there clearly doesn't realize that there are two main
contributors to the stratum-1 time keepers of NTP: dedicated atomic
clocks, and GPS.



Position correction is a statistical issue. Relativistic error is a
few hundred parts per trillion. Just how would that affect the
positions of each satellite when each is moving at much lower speed
than the speed of light? shrug

If you have troubles in counting
how far the satellite moves during 38 * n microseconds,
where n is number of days since last relativistic correction,
we can help you.



No, we can't as he is the stupidest man on Earth.
