Dear kallog,

Of course, it could not be used to measure linear velocity relative to the Sun.

I want to say is that Professor Wang's experiment

tells us that even if the straight line Sagnac effect also exists. Therefore, we have reason to believe that, the two-way time transfer experiment between China and Japan should be able to detect the Sagnac effect by the Earth 'revolution. At least it should be about 2000ns.
But we did not detect it. What does this mean?
