SR's first postulate is that physics is the same
in all inertial frames. If the detector of the
Cesium atoms is in the same inertial frame as
the source of the atoms in a Cesium clock system,
all Cesium clocks should run at the same
rate, - i.e. you can't measure
time dilation of your own inertial frame.
If so, Cesium clocks should all stay synchronized
without offset, irrespective of their relative
velocities with other clocks, if SR is correct.
The fact that they stay synchronized after offsetting
then would seem to disprove SR. But since the net
offset is for the effect of clocks speeding up (due to
GR supposedly) and not slowing down, nothing can be
concluded about time dilation due to velocity.
Your claim that the data proves LR then is also
highly questionable.
I think the same argument above applies to GR as
well if the source and detector of the Cs atoms
in Cesium clocks are at the same elevation relative
to each other, since according to GR, free fall
frames are equivalent. Thus, any offsetting of
clocks would seem to discredit SR and GR, and
not the reverse.
It is doubtful though that anyone running a highly lucrative operation would give out sensitive
data freely to the public so any information regarding
the GPS may be just numbers crunched by SR and GR
technicians and most likely do not
correspond to the actual operation of the GPS clocks.
So I think using the GPS in support of SR GR or any other R is little
more than idle speculation. But using the assumption that the data you provided is correct, I would think SR and GR have both been falsified. And since you cannot find a difference between your LR and the other Rs, your theory is falsified as well.

Tom and 123...90,
I think that we all agree on the fact the SR cannot be tested with the GPS. In any case, we don't need SR to explain the clock slowing.
Define two inertial frames of reference having a constant relative velocity. Place two persons, Alice and Bob, in these two frames individually. Give them identical ingredients, plans, procedures and tools to make a cesium clock. When both have completed their cesium clock, they measure each others ticking rate. Since the relative velocity of the two frames is known, Alice and Bob are able to account for doppler shift etc. to observe the ticking rate of the other moving clock.
Now, the ticking rate of the two clocks will be identical, since by symmetry of the system, they cannot differ. This is simple logic. However, when the frames pass and Bob throws his clock into Alice's frame, the clock is accelerated out of Bob's calibrated frame of reference and gains a different energy state (kinetic energy) with respect to its frame of calibration. When Alice throws back the clock, it will speed up and return to the energy state it was in before the throwing occured. There is no need to rescale length and time to acount for this.
Now the fun part, suppose Alice recalibrated Bob's clock to her own clock's ticking rate before throwing back the clock to Bob, then the clock will slow down in Bob's frame of reference. So when Bob receives his clock, he knows that Alice did something to it, because it simply should have gained its original ticking rate.
This is precisely where SR, I think, is going wrong. It does not account for different energy states of objects. Thus, when clocks accelerate out their frame of calibration, slowing occurs. Very intuitively and logically.
Because SR is stubbornly saying that energy plays no role, it is forced to rescale length and time parameters. This is like saying that my Ferrari is not going fast enough, so let us compress the road.
It should be noted that the acceleration did induce the clock slowing, but only as to get the clock into a constant different energy state with respect to the calibrated frame.
Let H:R^n -> R be a Hamiltonian, then whenever d/dt(H)=0, the clock rates will be stable, but when the energy changes in time, we can expect changes of the clock rate.
One nice thing, though, we don't need an absolute frame of reference. What we are saying is that the local preferred frame is the frame in which the calibration occured. So, the GPS clock slowing works nicely from this point of view. These things have been manufactured on earth, so as soon as we inject them into orbit, we do expect the ticking rate to change caused by the different kinetic energy state.
Any problems with the above mechanism?
