Dr. C.C. Su is one of the top experts in the world on electromagnetics:

C.C. Su, "A Local-ether model of propagation of electromagnetic wave," in Bull. Am. Phys. Soc., vol. 45, no. 1, p. 637, Mar. 2000 (Minneapolis, Minnesota).
Here is another paper, published by Dr. Su, on the local-aether model:
Journal of Electromagnetic Waves and Applications:
http://www.ee.nthu.edu.tw/ccsu/qem/f3c.pdfFor the interplanetary propagation, earth’s orbital
motion contributes to the Sagnac effect as well. This local-ether model
has been adopted to account for the Sagnac effect due to earth’s
motions in a wide variety of propagation phenomena, particularly the
global positioning system (GPS), the intercontinental microwave link,
and the interplanetary radar.
The paper is crap with no impact on the scientific discussion. It was published and peer-reviewed by the IOP, considered to be the highest standard of RE science:
http://iopscience.iop.org/article/10.1209/epl/i2001-00502-1M. Ruderfer proved in 1960 the FIRST NULL RESULT IN ETHER DRIFT THEORY.
The fact that the both the orbital Sagnac effect and the solar gravitational potential are missing from the GPS satellites means that its hypotheses are being fulfilled.
This is the main reason why relativists are giving up on Einstein's relativity.
They have to explain the missing orbital Sagnac effect.
They have two choices: either accept the Earth is stationary, or embrace the Lorentz ether theory; obviously they chose the latter.
Many other relativists have switched to the Non-time Orthogonal relativity theory, where the speed of light is no longer constant, but variable.
