Could it be that the gyroscope is detecting the movement of the dome, not the earth plane ifself?
The two domes are fixed (first dome separates our atmosphere from the high density ether which provides the rotational gravitational force which keeps the planets/stars moving; the second dome contains these stellar/planetary orbits).
Only the ether drift can rotate above the surface of the Earth.
However, the round earth believers will smile and show you the results of the Michelson-Gale experiment (1925), where Michelson detected fringe shifts which he promptly assigned as being a proof of the rotation of the Earth (he claimed that his formula is the SAGNAC EFFECT formula). Every ring laser gyroscope will also detect rotation, the formula used for the RLGs is the one derived by Michelson.
You then might say: "well, this is not the Sagnac effect, but the Coriolis effect of the ether drift". Then, you will be kindly asked to provide such a formula. Do you have a Sagnac effect formula for the MGX? You do not. Einstein, Lorentz, Michelson, Post could not provide one. So the RE win all the way, no matter how many proofs (200 or 500) are presented which show that the Earth is not rotating.
Michelson provided the biggest subterfuge in the history of science (Kepler's fake data in Nova Astronomia, Newton's fake attractive gravitational force pale by comparison): he assigned the CORIOLIS EFFECT formula to the SAGNAC EFFECT.
"Sagnac effect is a change in propagation time for light going in a closed path. The time delay Δt appears when a test equipment is rotated with an angular velocity Ώ. Sagnac effect is frequently used in rate gyros in navigational systems. Fiber optics is used with light-speed c inside the fiber in a circular light path. The difference in propagation time Δt for two opposite directions of light is described as
Δt = 4AΩ/c^2
Where A is enclosed area. Δt is derived based on an integration of Ω over A.
According to Stokes' rule can an integration of angular velocity Ω over an area A be substituted by an integration of tangential component of translational velocity v along the closed line of length L limiting the given area. This interpretation gives
Δt = 4vL/c^2
producing the same value as the earlier expression. This can also be demonstrated by geometrical relations.
These two integrations have different physical implications. We must therefore decide which one is correct from a physical aspect. Mathematics can not tell us that. So the decision is whether the effect is caused by a rotating area or by a translating line. Since Sagnac effect is an effect in light that is enclosed inside an optical fiber we can conclude that Sagnac effect is distributed along a line and not over an area.
No light and no rotation exists in the enclosed area. Sagnac detected therefore an effect of translation although he had to rotate the equipment to produce the effect inside the fiber.
We conclude that the later expression
Δt = 4vL/c^2
is the correct interpretation."

"Sagnac effect is distributed along a line and not over a surface. The assumption that starts from an integration over a surface (2Aw; rotation) is mathematically correct (due to Stokes' rule) but equal to a line integral (vL; translation). We must decide if the reason is a translating line or a rotating surface from a physical point of view. The rotation theory is correct only mathematically. Since the effect is locked inside an optical fiber the translating line is the correct interpretation. Classification as a rotational effect is wrong."
Professor Ruyong Wang has proven the Sagnac effect applies to uniform/translational/linear motion:

Therefore, the formula for the Sagnac phase shift which features the area and the angular velocity IS INCORRECT. Only the formula which includes the linear velocity is CORRECT.
You see, Georges Sagnac used the formula which features an AREA to describe the effect he discovered (an earlier version was provided by Oliver Lodge), since at that time (1913) no one understood that Stokes' theorem could be applied to an interferometer.
Michelson picked up Sagnac's omission and went all the way with it in 1925.
