Therefore, the existence of superluminal velocities (as already observed) by itself disproves the relativistic and classical formulas
absolute motion has already been detected in several experiments such as the Silvertooth
EM emission is instantaneous.

Top title says acceleration causes Doppler effects. It doesn't. Rate of change of distance (different than speed) causes Doppler effects. How much do the makers of this video know if they don't know the difference?
Ron Hatch is an expert in the use of GPS for precision farming, as well as other high precision applications. He is now a private consultant, having retired from John Deere, where he was formerly the Director of Navigation Systems Engineering and a Principal and co-founder of NavCom Technology, Inc., a John Deere company. NavCom provides a commercially operated differential GPS augmentation service to the agriculture industry and other high accuracy users.Throughout his more than 50 year career in satellite navigation systems with Johns Hopkins Applied Physics Laboratory and companies such as Boeing and Magnavox, Hatch has been noted for his innovative algorithm design for Satellite Navigation Systems. He has consulted for a number of companies and government agencies developing dual-frequency carrier-phase algorithms for landing aircraft, multipath mitigation techniques, carrier phase measurements for real time differential navigation at the centimeter level, algorithms and specifications for Local Area Augmentation System, high-performance GPS and communication receivers, and Kinematic DGPS. In addition to the Hatch-Filter Technique, Hatch has obtained numerous patents and written many technical papers involving innovative techniques for navigation and surveying using the TRANSIT and GPS navigation satellites. He has also authored "Escape From Einstein" and has published multiple papers in which he challenges current relativity theory. In 1994, Hatch received the Johannes Kepler Award from the Institute of Navigation (ION) for sustained and significant contributions to satellite navigation. In 2000 he received the Thomas L. Thurlow Award and was elected a Fellow of the ION. He has also served the ION as both the Chair of the Satellite Division and as President.

How much do the makers of this video know if they don't know the difference?It doesn't say that acceleration causes Doppler effects. Instead, it says Doppler frequency changes.
A source with constant "rate of distance change" produces shifted frequency due to Doppler effect, but the received frequency itself is constant (not changing with time).
Acceleration makes the rate itself continuously changing, hence the received frequency also changes accordingly.
Based on the information in the "Official U.S. government information about the Global Positioning System (GPS) and related topics" website, I think he knows a lot. https://www.gps.gov/governance/advisory/members/hatch/QuoteRon Hatch is an expert in the use of GPS for precision farming, as well as other high precision applications.

Same diff. The effect is a frequency change or frequency shift.
Argument from authority fallacy. How does quoting this guy's credentials make the statement in that slide correct?
Acceleration doesn't do that. I can accelerate an object without changing the rate of distance change, and I can change the rate of distance change without acceleration. Just think of a siren passing you by. The sound frequency drops as it passes, all without acceleration of the passing vehicle.
Sounds like another denier. People publishing such papers tend to be well versed in twisting the facts. Look at all the people making similar claims in New Theories section. Oh wait, you're one of them.

Don't you think that acceleration causes changing Doppler frequency shift?

For satelite case, it's only happens at the center of the earth, which is not a practical place to put an observer.

I did not. I have no idea who the guy is other than what you told me, so I have no reason to question those credentials. I was only commenting on the incorrect statements I saw on that slide.Evan just above seems to know the history of the person and is aware of how his ideas have been falsified, but I see nothing in his post that denies the credentials you gave. My statement above just says that a list of credentials doesn't make what he says correct, despite your implication otherwise.
I didn't say source movement caused it, and neither does acceleration. I said it is caused by the rate of distance change from source to observer.
I seemed to have based that statement only on your selection of video's to post, so I take it back. My apologies.
The geosync satellites both move and accelerate, and yes, that indeed produces a change of position. Yet the distance to them does not change, so no Doppler effect.
You have an example of that with light?
