Why would GPS need relativistic corrections?. If GR were
correct you wouldn't need to do any correction at all in the
orbital atomic clocks. It would suffice to perform relativistic
computations in the receiver device. I'll tell you what is
happening. You put relativistic corrections on those
orbital clocks, trying to synchronize them. Then, when
the PGS signals are received by a receiver device, it
performs relativistic computations. Why? Because it is
required to undo the relativistic offsets!. IOW, firstly you
put the error in the orbital clocks, and then the receiver must
undo that error if you want to attain a good GPS position.
That sounds like a farce!

It's classified information (top secret), but military GPS
do use neither GR corrections nor relativistic computations.
And you won't give that classified information to the enemy,
will you?

It's even worse.
The commercial receivers don't work because the information
the manufacturers need to make them work is kept secret.
The whole GPS thing is a conspiracy to make the public
believe that the GR is correct.

Did you actually think that commercial GPS receivers worked? :-)

Therein lies Tusseladd's conspiracy theory.
Do you actually believe ("think" would not apply, we know you can't)
that commercial GPS receivers designed by engineers work by Einstein
magic? :-)
