Are they going to release the Doppler rate if change data in relation to the Inmarsat?

I thought that the entire reason Immarsat was able to distinguish between the N arc and the S arc was because their satellite is not perfectly stationary above the earth but happens to move about a bit, which creates a second doppler shift which obviously varies according to which way the satellite happens to be moving.

It's called a scoop, I think. Possibly photographed by one of the families.

Ping arc data released

Probably just an error in the chart, (or my brain), but isn't the Ping 4 arc inside Ping 1 Arc - roughly -29?

Sorry, my poor labelling; '-' in the legend means 'minus'

So Final ping arc = 00:11UT
Ping arc - 1 = 22:41 Ping arc - 2 = 21:41
Ping arc - 3 = 20:41
Ping arc - 4 = 19:41


I didn't model the pings at around 18.30 as it is not clear how they relate to the final constant speed route.

Correct the INMARSAT satellite moves in an extended thin North South figure of 8 (geoloocated as opposed to geostationary ) This provides two levels of Doppler shift due to the aircraft and the satellite.

buttrick:
can you draw a line that ends up in the yellow final search box, with constant but much less speed?
Appears to me ground speed to be more 250 knots than 489 knots.
There is still something missing here.

"The posts relating to the Georesonance stuff have all been removed, rightly"

Why rightly?

Because GeoResonance is either a hoax or a scam or both, and just because a TV station fell for it, we don't need to perpetuate their claims further here.

I suggest to the moderators to leave one edited post in the thread noting why a certain group of posts has been removed so future questions about the issue can be avoided.

Because everyone knows they are searching in the right place and it must be right for something they lost and cannot find.
Last time I lost my wallet I was sure I lost it at home...I did not bother looking at work as I knew it was not there. Cannot help thinking the same thinking applies here. The trace must be right because we say so.

Satellite data and related

@ oldoberon

Not challenging the correctness of your statements. Nonetheless, we want to know your basis of knowledge. That is: your statements about the tasks and methods utilized by the individuals and/or entities to determine the satellite-related data are:
(a) derived from first-hand knowledge of how the data were handled, because you were there and participated (in whole or in part), or
(b) derived not from personal knowledge but rather from knowledge about how the pertinent individuals and/or entities do things such as the effort to plot the flight path of the missing airliner, or
(c) derived, somehow, through some other means.

Again I'm not asserting disagreement. What I am saying is we want to know how much reliance may be placed on your statements, as a function of how you acquired the knowledge you have posted.

Now all they need is some legit data.

I can't believe they are getting any publicity at all, guess it shows how desperate the journos are to turn up new stuff, anything at all, on the fate of the aircraft.

Satellite and related

Willow,
The document released by Malaysia on 25/03/14 is titled:
Information Provided to MH370 Investigation by UK Air Accidents Investigation Branch (AAIB)

The first sentence reads "On 13 March we received information from UK satellie Company Inmarsat...." (my emphasis on "we"

The second sentence reads" Inmarsat UK has continued to refine this analysis and yesterday the AAIB presented it's most recent findings,..."

The Satellite data originated from Inmarsat, and that data (and it's findings) were presented to Malaysia by AAIB.

I'm not certain that any of us can attest that NTSB reviewed or approved the Inmarsat analysis.

You could question whether AAIB reviewed the Inmarsat data, but it is reasonable to presume that the AAIB did so.

About the ping data

Instead of arguing about how the data should have been or might have been handled and how official ..

Why not simply go to Inmersat at

Malaysian government publishes MH370 details from UK AAIB - Inmarsat

Right or wrong - I am sure they have had multi- experts and some equivalent tracking data for flights by 777 in the general areas.

PLease forget- the Diego garcia and wazooistan theories unles one has better data from credible sources.

That sort of leaves out CNN for many issues.

Malaysian officials said they are assessing the claim by Adelaide-based GeoResonance.
“We’re not trying to say it definitely is MH370, however we feel it is a lead that should be followed up by the authorities,” GeoResonance director David Pope told Channel 7 News.
The company used imaging, radiation chemistry and other technologies to search the 2 million square kilometres of the ocean floor for chemicals that are found in Boeing 777 jets, and discovered aluminium, titanium, jet fuel residue and other elements in the Bay of Bengal.
GeoResonance compared images taken March 5 and 10 — before and after the plane’s disappearance — and found differences that could indicate a crash site.
The location is about 190 kilometres south of Bangladesh.
The company has been contacted by Malaysian officials, and was asked to give a presentation on its finding, Channel 7 reports.
“We’re a large group of scientists, and we were being ignored, and we thought we had a moral obligation to get our findings to the authorities,” Mr Pope told CNN.
Seems like the Malaysians are not dismissing GeoResonance's claim out of hand - but they want a properly-outlined presentation.
To me, it appears that the GeoResonance director is backing away from the initial claims that they actually found MH370.
Whether that claim was actually made by the company, or was made by the media in an unwarranted extrapolation of the initial information, is a moot point at this stage.

I can accept that GeoResonance has found all the materials that they have spoken of - but whether they come from MH370 or another crashed jet aircraft that has never been found, is something that needs to be investigated promptly, by researching aircraft crash records.

It could definitely be worth a check as apparently the depth is not too great there. If it does turn out to be an aircraft wreck and not the right one it is another mystery solved. If it does prove to be a wreck the technique may be worth a try in the deeper water where they think MH370 crashed.
