You lack the most basic knowledge of astrophysics.
http://hypertextbook.com/facts/2002/JasonAtkins.shtmlIf we multiply, as an example, this value by the Earth's equatorial radius we will of course get an equatorial speed of 465.1 m/s, 1,674.4 km/h or 1,040.4 mph.
However, the orbital speed of the Earth around the Sun is some 30 km/s.
TWO DIFFERENT MOTIONS: the GPS satellites must incorporate both the rotational Sagnac effect AND the orbital Sagnac effect.
The second effect, the orbital Sagnac effect IS NOT recorded.
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.
http://qem.ee.nthu.edu.tw/f1a.pdfWhy is there no requirement for a Sagnac correction due to the earth’s orbital motion? Like the transit time in the spinning Mossbauer experiments, any such effect would be completely canceled by the orbital-velocity effect on the satellite clocks.
However, indirectly, the counteracting effects of the transit time and clock slowing induced biases indicate that an ether drift is present. This is because there is independent evidence that clocks are slowed as a result of their speed.
Thus,
ether drift must exist or else the clock slowing effect would be observed. The fact that the orbital Sagnac effect is not recorded by GPS satellites is a basic assertion of modern physics.
For you to state something like this: "
There is no need for a separate "orbital Sagnac effect" calculation." means you haven't got a clue as to the subject we are discussing here.
As for Neil Ashby, here are two papers detailing the terrible errors committed by Ashby:

In addition to the fact that GPS satellites do not record the orbital Sagnac effect, we have an even greater problem: the GPS clocks DO NOT RECORD the Sun's gravitational potential.
It is assumed that the orbital velocity of the Earth as it orbits the Sun is a variable; however, the GPS clocks show that the this velocity MUST BE CONSTANT, as it does not record the Sun's gravitational potential effect upon these clocks.
