For 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 peer reviewers at the Journal of Electromagnetic Waves and Applications agree that the orbital Sagnac is larger than the rotational Sagnac, that it is missing, and that a local-ether model has to be adopted in order to account for this fact.

The author recognizes the earth's orbital Sagnac is missing whereas the earth's rotational Sagnac is not.

He uses GPS and a link between Japan and the US to prove this.

In GPS the actual magnitude of the Sagnac correction

due to earth’s rotation depends on the positions of

satellites and receiver and a typical value is 30 m, as the

propagation time is about 0.1s and the linear speed due

to earth’s rotation is about 464 m/s at the equator. The

GPS provides an accuracy of about 10 m or better in positioning.

Thus the precision of GPS will be degraded significantly,

if the Sagnac correction due to earth’s rotation

is not taken into account. On the other hand, the orbital

motion of the earth around the sun has a linear speed of

about 30 km/s which is about 100 times that of earth’s

rotation. Thus the present high-precision GPS would be

entirely impossible if the omitted correction due to orbital

motion is really necessary.

In an intercontinental microwave link between Japan and

the USA via a geostationary satellite as relay, the influence

of earth’s rotation is also demonstrated in a high-precision

time comparison between the atomic clocks at two remote

ground stations.

In this transpacific-link experiment, a synchronization

error of as large as about 0.3 µs was observed unexpectedly.

Meanwhile, as in GPS, no effects of earth’s orbital motion

are reported in these links, although they would be

easier to observe if they are in existence. Thereby, it is evident

that the wave propagation in GPS or the intercontinental

microwave link depends on the earth’s rotation, but

is entirely independent of earth’s orbital motion around

the sun or whatever. As a consequence, the propagation

mechanism in GPS or intercontinental link can be viewed

as classical in conjunction with an ECI frame, rather than

the ECEF or any other frame, being selected as the unique

propagation frame. In other words, the wave in GPS or the

intercontinental microwave link can be viewed as propagating

via a classical medium stationary in a geocentric

inertial frame.

motion of the target planet contribute to the Sagnac

effect. But the orbital motion of the sun has no effects

on the interplanetary propagation. On the other hand, as

the unique propagation frame in GPS and intercontinental

links is a geocentric inertial frame, the rotational motion

of the earth contributes to the Sagnac effect.

**But the orbital**

motion of the earth around the sun and that of the

sun have no effects on the earthbound propagation. By

comparing GPS with interplanetary radar, it is seen that

there is a common Sagnac effect due to earth’s rotation

and a common null effect of the orbital motion of the sun

on wave propagation.

**However, there is a discrepancy in**

the Sagnac effect due to earth’s orbital motion. Moreover,

by comparing GPS with the widely accepted interpretation

of the Michelson–Morley experiment, it is seen that

there is a common null effect of the orbital motions on

wave propagation, whereas there is a discrepancy in the

Sagnac effect due to earth’s rotation.

Based on this characteristic of uniqueness and switchability of the propagation frame,

we propose in the following section the local-ether model

of wave propagation

**to solve the discrepancies in the in-**

fluences of earth’s rotational and orbital motions on the

Sagnac effect and to account for a wide variety of propagation

phenomena.

**Anyway, the interplanetary Sagnac effect is due to**

earth’s orbital motion around the sun as well as earth’s

rotation. Further, for the interstellar propagation where

the source is located beyond the solar system, the orbital

motion of the sun contributes to the interstellar Sagnac

effect as well.

Evidently, as expected, the proposed local-ether model

accounts for the Sagnac effect due to earth’s rotation and

the null effect of earth’s orbital motion in the earthbound

propagations in GPS and intercontinental microwave link

experiments. Meanwhile, in the interplanetary radar, it accounts

for the Sagnac effect due both to earth’s rotation

and to earth’s orbital motion around the sun.

Based on the local-ether model, the propagation is entirely

independent of the earth’s orbital motion around

the sun or whatever and the velocity v for such an earthbound

experiment is referred to an ECI frame and hence

is due to earth’s rotation alone.

** In the original proposal,**

the velocity v was supposed to incorporate earth’s orbital

motion around the sun. Thus, at least, v^{2}/c^{2}

=~ 10^{-8}. Then the amplitude of the phase-difference variation

could be as large as π/3, when the wavelength is

0.6 µm and the path length is 10 m. However, as the velocity

v is the linear velocity due to earth’s rotation alone,

the round-trip Sagnac effect is as small as v^{2}/c^{2}∼ 10^{-12} which is merely 10^{-4} times that due to the orbital motion.The Sagnac effect is a FIRST ORDER effect in v/c.

Even in the round-trip nature of the Sagnac effect, as it was applied in the Michelson-Morley experiment, thus becoming a second order effect within that context,

**we can see that the ORBITAL SAGNAC IS 10,000 TIMES GREATER than the rotational Sagnac effect.**Your statement has just been refuted and debunked: the orbital SAGNAC effect is missing.

LISA Space Antenna

The LISA interferometer rotates both around its own axis and around the Sun as well, at the same time.

That is, the interferometer will be subjected to BOTH the rotational Sagnac (equivalent to the Coriolis effect) and the orbital Sagnac effects.

Given the huge cost of the entire project, the best experts in the field (CalTech, ESA) were called upon to provide the necessary theoretical calculations for the total phase shift of the interferometer. To everyone's surprise, and for the first time since Sagnac and Michelson and Gale, it was found that the ORBITAL SAGNAC EFFECT is much greater than the CORIOLIS EFFECT.

The factor of proportionality is R/L (R = radius of rotation, L = length of the side of the interferometer).

Algebraic approach to time-delay data analysis: orbiting case

http://iopscience.iop.org/article/10.1088/0264-9381/22/10/040/metaIn this work, we estimate the effects due to the Sagnac phase by taking the realistic model for LISA orbital motion.

This work is organized as follows: in section 2, we make an estimate of Sagnac phase

for individual laser beams of LISA by taking realistic orbital motion. Here we show that, in general, the residual laser noise because of Sagnac phase is much larger than earlier estimates.

For the LISA geometry, R⊙/L is of the order 30 and the orbital contribution to the Sagnac phase is larger by this factor.

The computations carried out by Dr. R.K. Nayak (over ten papers published on the subject) and Dr. J.Y. Vinet (Member of the LISA International Science Team), and published by prestigious scientific journals and by ESA, show that the orbital Sagnac is 30 times greater than the rotational Sagnac for LISA.

CALTECH acknowledges that the ORBITAL SAGNAC EFFECT is not being registered by GPS satellites.

In the SSB frame, the differences between back-forth delay times are very much larger than has been previously recognized. The reason is in the aberration due to motion and changes of orientation in the SSB frame. With a velocity V=30 km/s, the light-transit times of light signals in opposing directions (Li, and L’i) will differ by as much as 2VL (a few thousands km).

SSB = solar system barycenter

https://arxiv.org/pdf/gr-qc/0310017.pdfWithin this frame, which we can assume to be Solar System Barycentric (SSB), the differences between back-forth delay times that occur are in fact thousands of kilometers, very much larger than has been previously recognized by us or others. The problem is not rotation per se, but rather aberration due to motion and changes of orientation in the SSB frame.

The kinematics of the LISA orbit brings in the effects of motion at several orders of magnitude larger than any previous papers on TDI have addressed. The instantaneous rotation axis of LISA swings about the Sun at 30 km/sec, and on any leg the transit times of light signals in opposing directions can differ by as much as 1000 km.

Aberration due to LISA’s orbit about the Sun dominates its instantaneous rotation.

The ORBITAL SAGNAC calculated at the Jet Propulsion Laboratory amounts to an admitted difference in path lengths of 1,000 kilometers.

The difference in path lengths for the rotational Sagnac is 14.4 kilometers:

https://gwic.ligo.org/thesisprize/2011/yu_thesis.pdf (pg. 63)

Therefore the difference in path lengths for the ORBITAL SAGNAC is some 60 times greater than the difference in path lengths for the rotational Sagnac, according to these calculations.

You have to accept reality: CALTECH/NASA/ESA is telling you that THE ORBITAL SAGNAC EFFECT IS MISSING.

*Actually, you must provide the ATTRACTIVE MECHANISM which keeps the falling object next to the surface of the flat stationary Earth.*Cut the crap.

There is no need for an attractive mechanism on FLAT, STATIONARY surface of the Earth.

* nor does it make any empirical sense. I mean what's the calculation for absorption? How much ether do I absorb? How much does an apple absorb? None of your claim makes sense without knowing how this 'absorption' works.*The displaced volume of ether and the density of the object determines the quantity of aether that is being absorbed. This has been explained clearly.

How the absorption works has been explained as well, all the way down to the antiboson level.

“This implies an important conclusion: bodies of different volumes that are in the same gradient medium acquire the same acceleration.

Note that if we keep watch on the fall of bodies of different masses and volumes in the Earth’s gravitation field under conditions when the effect of the air resistance is minimized (or excluded), the bodies acquire the same acceleration. Galileo was the first to establish this fact. The most vivid experiment corroborating the fact of equal acceleration for bodies of different masses is a fall of a lead pellet and bird feather in the deaerated glass tube. Imagine we start dividing one of the falling bodies into some parts and watching on the fall of these parts in the vacuum. Quite apparently, both large and small parts will fall down with the same acceleration in the Earth’s gravitation field. If we continue this division down to atoms we can obtain the same result. Hence it follows that the gravitation field is applied to every element that has a mass and constitutes a physical body. This field will equally accelerate large and small bodies only if it is gradient and acts on every elementary particle of the bodies. But a gradient gravitation field can act on bodies if there is a medium in which the bodies are immersed. Such a medium is the ether medium. The ether medium has a gradient effect not on the outer sheath of a body (a bird feather or lead pellet), but directly on the nuclei and electrons constituting the bodies. That is why bodies of different densities acquire equal acceleration.

Equal acceleration of the bodies of different volumes and masses in the gravitation field also indicates such an interesting fact that it does not matter what external volume the body has and what its density is. Only the ether medium volume that is forced out by the total amount of elementary particles (atomic nuclei, electrons etc.) matters. If gravitation forces acted on the outer sheath of the bodies then the bodies of a lower density would accelerate in the gravitation field faster than those of a higher density.

The examples discussed above allow clarifying the action mechanism of the gravitation force of physical bodies on each other. Newton was the first to presume that there is a certain relation between the gravitation mechanism and Archimedean principle. The medium exerting pressure on a gravitating body is the ether.”
