Maybe your unnecessary elaboration of details keeps you from seeing
the basic error in your approach. Maybe you are assuming that the craft

I am not absolutely sure there might not be a delay circuit and it is
possible also that when the coding is going on the craft is not
relaying the carrier but emitting its own carrier so that there is a
change in the frequency being emitted etc.that contributes to the data
that is observed.

You don't seem to grasp the fact that the craft could turn off
the transponder when decoding is going on and so the next transponded
in phase relayed uplink to downlink occurs later,or that the craft one
way communication is substituted for the transponder relay of the
uplink to downlink or something else involving a delay circuit.

But they do use it and they need to use it to correct the mistakes
made by these other measurements which assume the wrong light speed
delay and to confirm what subsequent doppler and range show. I have
been told this by those working at the antenna sites.

The corrections I showed you and you acknowledged are much larger.
They may be due to gr effects but this is not clear at all especially
the 90 Hz you refer to or to the .004Hz you refer to. There is no time
delay so the curvature of spacetime does not apply and it is not clear
how changes in the infinitessimally faster reception of the carrier
frequency received on the craft minute by minute as the craft gets
further from the sun and jupiter will cause changes in the doppler each
minute so that increasing errors on the order of 10Hz are observed. And
maybe changes in the transponder phase matching compensates for this.

You get a grip. I am talking about the conventional model and its
error. My model and the error difference between my model prediction
and the observed Doppler is a red herring because it assumes the wrong
initial position and velocity and so must be larger.
Your attempt to use this to show that the nearly instantaneous
hypothesis is disproven is disingenuous.

You don't mean flight parameters, you mean position and velocity
estimates based on wrong speed of light delay assumptions and yes that
is the point they were constantly changed to correct for the errors due
to the false speed of light delay assumptions.
And what I am proposing is that if the correct speed of light dealy
assumptions were used with the same received carrier frequency doppler
shift data that there would be no need to make repeated corrections.

So they do apply specific corrections the way I think
they do and the way you think they do.
The wandering is slight minute by minute but it is cumulatively
quite large. This wandering would not require unjustifiably large
estimates of solar radiation and planetary dust effects if the correct
assumptions about the speed of light were made

I understand how it works but you don't understand how it could be

But the line to the craft is not in the equatorial plane
or as near to it as you assume making the false speed

But we are not projecting a circle so as to get an ellipse or a
straight line, we are projecting a line representing the orbital
velocity at a site and a line representing the spin velocity at
the same site. These lines are projected through unknown
angles onto the unknown craft to site lines at these sites.
As the earth spins, the spin velocity at each earth site will
at some time at each site be perpendicular to the unknown
earthsite to craft line at each of these sites but the total
velocity line at these times at these sites may not be

This 26 degrees is due to your assumption that the
the orbital velocity has no effect.

No need to go beyond that. He repeated exactly this as part of a
saying nearly instantaneous communication with the craft was
therefore impossible and that the communication had to have been
relayed from another site at a much earlier time. As far as I am
concerned this was a lie repeated again and again.

The posts were many and many repetitions of the same lie that you
anyone can see them all by looking at the archives.

This is all unclear. I suspect that the relativistic
effect is a red herring and that the changes minute
by minute in the Doppler caused by this are negligible.

Both may have referred to something else but my analysis
did assume it was negligible. But you are right. This is all unclear.
I suspect that the relativistic effect is a red herring and that the
by minute in the Doppler caused by a more rapid reception of
the carrier by the craft, as the craft gets further from jupiter and
is compensated for by the phase adjustment in the craft transponder.
The delay in carrier reception associated with light bending due to
only occurs when reception is during the day so does not explain the
systematically increasing effect shown by the data.

Don't be so foolishly pretentious. I have explained
to you what is wrong with your assumptions and you
can only repeat such errors in the simple assumptions
and play with fecal details again
and again. You have done this twice before with the doppler shift
implying the speed of light interpretation of light reception delay
and re binary stars implying the speed of light interpretation.
I would have thought the lesson had been learned.
