Inmarsat interrogated MH370's pings to plot final route
LONDON (Reuters) - Britain's Inmarsat used a wave phenomenon discovered in the nineteenth century to analyze the seven pings its satellite picked up from Malaysia Airlines Flight MH370 to determine its final destination. Inmarsat's scientists then interrogated the faint pings using a technique based on the Doppler effect, which describes how a wave changes frequency relative to the movement of an observer, in this case the satellite, a spokesman said. "We then took the data we had… (www.reuters.com) 更多...

I knew of Inmarsat as a mobile communications satellite operator. I didn't realize until this MH370 incident that they were also in the business of NSA'ing customer data. If I ever need mobile comms, I'll have to think twice about using Inmarsat or else buy terminals that will encrypt my transmissions.
They have only narrowed down the location to a muli-hundred square mile area, that will have to be meticulously searched by lots of multi-million dollar equipment and much personnel, all at astronomical cost.
It would be much, much easier to find an IPhone or any other modern communication device that has a GPS circuit to triangulate its' location, and which communicates that location with an external source such as mobile operator server.
You'd have to go real old-school (eg. old analog phone without GPS) to not be tracked.
Inmarsat did some esoteric evaluation of the recorded ping data just to get an aproximate distance and aproximate direction of that signal. Very aproximate.
GPS coordinates would be much more precise. They can land a GPS-directed missile on your head with your cell phone/ sat phone coordinates.
In comparison, getting a gereral idea of location somewhere between Paris Frankfurt and Geneva isn't very useful, after hours of analysis is quite as useful.

" ... The incident is likely to spur a review of aviation rules, especially related to communications equipment and the ability to turn off a plane's transponder, he added. ... "
An idea when I tried to promote as a non aviator, some so called expert fliers jumped up to use as foul a language as they could to degrade me.
So sad!
And this is not the first time or the first article suggesting the improvement in the avionics in this context.
I wonder what will all non technical persons like pilots say ?
I again say, day is not far when communication system will be made independent from interference by the pilots ! Like switching off the transponders. And you never know, law and engineers may come up with some additional back up systems to counter terrorist activities or a lunatic pilot !
Already so many steps and gadgets are in place and continue to be developed to make air space and flying as safe as possible.

This addresses definitively the questions of those who wonder of the missing plane heading due west out over the Indian Ocean in the general direction of the Maldives, after pilots turned the plane around to an alternate airport on the Malaysian peninsula and then succumbed to whatever danger initiated the diversion before landing at said alternate airport.
Like you seem to be meaning, the "pings" are not for photo competition but for technological interpretations !
And now, as is being circulated, the BB is beaming its signals and 'calling' for the attention of SAR teams, "fellas, come and find me", hidden and resting may be thousands of meters down under on the seabed !
