I think science has become problematic. Its been marketed as factual but is now more an ideology than scientific principle. Check the "Science delusion" thread for more.

Inmarsat’s use of data helps solve MH370 flight path riddle
The team used the “Doppler effect” of the satellite as it moved in its orbit to establish a set of measurements for the predicted northerly and southerly paths, a company spokesman said. The Doppler effect describes the change in the frequency of sound, radio or light waves as they travel between two objects, when one or both of them are moving.
The team then overlaid these measurement with data from other aircraft that had flown both “arcs” and the results corresponded with the southerly route. Inmarsat had the results peer-reviewed before passing them on to the Malaysian authorities.Ben D » Tue Mar 25, 2014 12:04 pm wrote:It is possible to determine direction quite easily by comparing doppler effect of the MH370 signal with known doppler measurements of signals of north and south travelling aircraft...the satellite serving as the reference point.
Regarding what I had said earlier about how easy it is to detect doppler shift on a carrier wave to the satellite, while this is correct in principle, in this instance wrt the above piece, with rereading and reflection I deem the story B/S. Doppler shift can be only detected on the carrier wave itself in real time processing or if the carrier wave was recorded at the time and processed later, not on the modulated signal of the carrier which has been demodulated and recorded , and since the carrier wave in this instance is not recorded, there can be no post signal reception process to ascertain a doppler shift of the real time event.
but I'm afraid this is just another part of a concerted effort to muddy the waters to the point where no one can figure out what's true and what's disinformation.
