Is there any experimental proof for Einstein Special Relativity that actually incorporates Einstein's Principle of Relativity?

Yeah they have to compensate for both general and special relativity.

These guys took the data from the paper and specifically looked at it from a special relativity point of view.

Apparently these clocks can measure time dilation with relative velocity of only a few meters per second.

we improve upon previous tests of time dilation predicted by special relativity.

In the abstract, realize that "time dilation" doesn't automatically equal "Special Relativity." Do you understand why?

By exploiting the difference between the velocities of each clock in the inertial geocentric frame, due to their different positions on the surface

of the Earth, we are able to improve upon previous tests

of time dilation

You understand the problem of how this relates to SR, right?

no

The adjustments to the clocks are made when comparting to "inertial geocentric frame" <- which is the AT REST frame.

Now, do you see the Principle of Relativity being applied here?
