Your keyboard is b0rked.

That does not change the fact that we know with great confidence what 
“happens the clocks” – from *different* perspectives –, knowing how they
are constructed, and were adjusted before being sent into the terrestrial
orbit, and that they are synchronized with clocks on the ground daily, to 
fulfill their purpose in that orbit.

I am not.

In any case, I think that you, being a particle physicist, are particularly 
well aware that observing an object does not need to mean to see that object 
with one’s own eyes, but means *receiving information* about the state of 
the (assumed) object in *any* way.  For that, what I said holds.  (You are 
just too hung up on the particular example to see that.  If that helps, 
modify in your mind the GPS satellite to additionally send video of the 
display of the clock to the ground, and reconsider.)

AISB, for the reasons that I have given, it is a fallacy, and _not_ backed 
up by relativity, to assume otherwise – including to assume that for all 
observers an object has only one state, the one observed in its rest 
frame –, as you continue to do:

I am sorry if you cannot see that, but you can keep your unfounded/badly 
founded, impolite berating to yourself.  It is not the one who shouts the 
loudest who is right, but who presents the better argument.  Evidently you 
have not even thought about my argument, you just continue your strawman 
fallacies (arguing against positions that I simply did not take).
