Well of course everything is done currently in the station and always

that same 2.292 imprimatur. And it must use it some way to produce the
total frequency fmod = f0 - vf0/c, of which the 2d term is
negligible. f0 is added to the converted velocity stream in the model
(f87 in my diagram).

But meanwhile the real clock frequencies have theoretically moved on
up by f0Ht with no one able to prove otherwise, right from clocks that
are currently certified as 2.292. NIST nor any one else can decide.
The declaration of 133Cs being 9,192,631,770 cycles to equal 1

My premise is by no means disproved in arXiv:gr-qc/0104064. It has not
been properly tested there as I will show.

Eq. 60 purportedly seeks to find whether "drifting clocks" could

...

However, equation 60 of Anderson et al is not the only drifting clock
model considered. As George points out, equation 62 is essentially
your model, and is also inconsistent with the full data set. Thus,
your discussion of equation 60 is irrelevant.


You must have missed my note to George where I admitted it should be
Eq. 62 but your "Drifting Clocks" remark steered me to Eq. 60 .

At Eq. 62 the report says "This model adds constant frequency drift to
the reference S-band frequency. This model also fits Doppler well, but
again fits range poorly". That is an impossible conclusion.

This can be clarified by looking at the flowgraph on my website. It
seems hardly possible that a constant frequency drift added at
"f-adjust" downstream, could "fit range poorly" because range is
"upstream" at the left side of the diagram. In other words, the model
is self-sufficient at deriving velocity and range, but gets into
trouble when it tries to synthesize frequency in the right hand half.


What "seems hardly possible" to you is irrelevant. In fact, your flow
chart has nothing to do with the ranging observations to the other
spacecraft (note: the RANGE technique is different from DOPPLER).
Anderson et al's results have everything to do with the fact that *if*
the station frequency standards had been drifting, this would also
produce a temporal drift which would be inconsistent with ranging
data. The authors considered your hypothesis and can reject it based
on the observations.

[ And it's worth mentioning that if frequency standards were gradually
drifting linearly, then the accumulated phase error would build up
quadratically with time, and be detectable in the orbits of planets
and sattelites... but such a discrepancy is not detected. ]




Furthermore, as has been pointed out several times already, the
station clock is used as a reference frequency for both the
transmitter and the receiver. If frequencies were globally drifting
with time, a bias would be added at the transmit stage, but subtracted
at the receive/downconvert stage. Thus, your theory is erroneous.


The workmanship at the station is considered flawless.
But as I have already pointed out, the system does not have sufficient
resolving power to detect the anomaly in a normal round trip period. It
is only by tracking over the years that it became evident.

....

I note that you did not respond to the truly relevant criticism:
"If frequencies were globally drifting with time, a bias would be
added at the transmit stage, but subtracted at the
receive/downconvert stage."
Thus, the only "anomaly" that could be produced is during the time
between transmit and receive, i.e. the round trip light travel time.
And that is what the Anderson authors reject based on the full
doppler+ranging data set.

Sorry John but that IS what is done for the analysis, there
is no alternative since the actual transmit frequency has
step changes for engineering purposes. Once the speed
has been determined from those two values, it can of
course be applied to a hypothetical exact signal such as
2.92GHz, which is the nature of Eqn 15, but that is not
part of the actual analysis.

After all that is said, the point remains, Eqn 15 says
that after 8 years the actual received frequency at any
time exceeds the expected value from the model by
3Hz (round trip) so each point on the graph is 3Hz,
not the tiny amount you mentioned.

There is nothing phenomenological here. The anomaly comes from the

model while real clocks were advancing, albeit at a glacial rate.

The statement:

"real clocks were advancing, albeit at a glacial rate"

implies that all clocks increased montonically over time
"all clocks" would include Big Ben, London
my quartz wrist watch
and every quantum transition time (frequency)
including the one governing the station clock
as well as the 6E23 clocks per mole
of our known universe.

Is that what your are implying?

No, that's not how the anomaly is computed in gr-qc 0104064 . Look at

Note that a_P already appears in that equation. The
words preceding the equation explain:

"The observed, two-way anomalous effect can be
expressed to first order in v/c as:"


Eq. 15b says
fmod = f0(1-2v/c)
Just as well I can write Eq. 15c which says
fobs = f0(1-2v/c)
Then Eq. 15a subtracts the two and comes up with not 0, but
-F0*2Apt/c
which, since there is no proved Ap, can be more correctly be written
as
-H*f0*2 where H = Ap/c
It's all algebra with not one jot of physics.
But to include my thesis of all clocks increasing at H we have
fobs - fmod = v0(1+Ht)(1-2v/c) - f0(1-2v/c) comes down to
fobs - fmod = fo(1-2v/c)Ht ~ f0Ht
where whole frequencies are used.
As I had said. The v/c dynamics are plainly negligible (0.0004x).
If you want to compare Dopplers it would look like (but it's not Eq.
15)
(fobs-f0) - (fmod-f0) = fobs - fmod would equal zero if f0
was constant everywhere. But with an advancing station clock we have
instead
(fobs-f0[1+Ht]) - (fmod-f0) = f0Ht
This version of Doppler comparison works out but Eq. 15 doesn't use
it.

In other words, after the value of a_P has been

Exactly, it is all algebra. Figure 8 is produced by
plotting individual points as I explained above. It
is fairly easy to see the the result is close to a
straight line and Eqn 15 is then the algebraic
expression of the general form of such a line.

To understand what is being plotted however, you
need to consider how a value for Doppler shift is
produced, and the only way to do that when the
uplink changes from day to day is to find the
difference in frequency between the Tx and Rx
values. That is what was done.

Then your document is worthless because 3Hz per
sample is what the analysis produces at the end
of the period. Ask Craig, he has done the actual
work so can confirm from first hand knowledge. My
work (unpublished) has been based on the residuals
remaining from his analysis so is second hand but
required me to understand in detail how they were
derived. Your hypothesis is one that should be
considered but to match the frequency results, you
need to increase your clock drift rate by a factor of
about 10000. Doing that would give you a process
that matched the Doppler observations and the test
would then come done to a range comparison which
is a much more complex task given the absence of
direct range measurements.

My arguments and interpretation of anomaly of "Pioneers" can change

The principle of equivalence has been tested quite narrow tolerances

will probably not be fruitful.

I do not believe in Williams, Newhall & Dickey interpretation of
experimental data absolutely.

Please, try to explain a difference between measurements of values
of masses of Jove and Saturn by two different measurement methods
of masses of planets in two epoch distant from each other by interval
of time per 25 years:


Your reference to Jupiter and Saturn is irrelevant, since the
equivalence test in Williams Newhall & Dickey (1996), regarded the
independent accelerations of the *earth and moon* toward the sun. The
accelerations match to with one part in 5 x 10^{-13}, even though the
two bodies have a factor ~80 difference in mass.

Furthermore, your calculation,
Jove was 317.735 in 1970 and has become 317.89 in 1990
Saturn was 95.147 in 1970 and has become 95.168 in 1990

is both in error and does not account for measurement uncertainties.

Assuming measurement uncertainties in the final IAU 1976 values,
one obtains,
IAU 1976 IERS (2003)
M_jupiter / M_earth = 317.89(1) 317.8942(1)
M_saturn / M_earth = 95.17(1) 95.185(2)

uncertainties, and thus your claim reagarding mass differences is
irrelevant.

Can you derive the value of a_P with that theory?
