Let's try again:

- It is a fact that the rate of the SV-clock is corrected
according to the GR-prediction before launch.



That is a mere approximation to the required corection.
It makes a few purists happy...and does no real harm.


Calling the correction which is proven correct within
the precision of the clocks "a mere approximation"
does not refute the fact that the correction is correct
within the precision of the clocks. :-)


Paul, why don't you stop this stupid arguing.

The 'GR correction' is correct to the precision of the GR CORRECTION. 

Meaning what?

1. The GR prediction is that the relative rate difference of a clock
   in GPS-orbit compared to a clock on the ground is +4.4647E-10.
   This is the correct GR prediction with the precision +/- 1E-14.

2. The GR prediction is proven to be consistent with the observed
   rate of the clocks in GPS orbit within the precision of those
   clocks, which is in the order of +/- 1E-12.

It is of no practical significance and nobody operating the system gives a
stuff about GR. They don't need to.


And what is this babble supposed to mean?

You KNOW that:
- It is a fact that the rate of the SV-clock is corrected
  according to the GR-prediction before launch.

... which would not have been done if it was "of no practical
significance and nobody operating the system gives a stuff
about GR."

- It is a fact that the SV-clock never is corrected in any
way while the satellite is in service.
- It is a fact that the rate of the closely monitored
SV-clock is correct within the precision of the clock.

Do you refute any of these irrefutable facts?
Yes or no, please.
In that case, which one and why?
Be specific, please.


Paul, anything at all can happen in dreams. 

- which isn't even an attempt to refute any of the facts.

It is settled then.
Henri Wilson cannot refute any of the facts.


... so all he can do is to utter statements like this:

which is: The 'GR correction' is correct to the precision of the GR CORRECTION.


So we can sum it up:
- It is a fact that the rate of the SV-clock is corrected
 according to the GR-prediction before launch.
- It is a fact that the SV-clock never is corrected in any
 way while the satellite is in service.
- It is a fact that the rate of the closely monitored
 SV-clock is correct within the precision of the clock.

Which proves conclusively that the GR prediction is
correct within the precision of the clocks.


Don't pretend that you don't understand that this statement
means 2. above, and not 1.


The 'GR correction' is correct to the precision of the GR CORRECTION. 

You have still not refuted any of these facts:
- It is a fact that the rate of the SV-clock is corrected
  according to the GR-prediction before launch.
- It is a fact that the SV-clock never is corrected in any
  way while the satellite is in service.
- It is a fact that the rate of the closely monitored
  SV-clock is correct within the precision of the clock.

Which proves conclusively that the GR prediction is
correct within the precision of the clocks.
