Mar 25, 2014 at 14:14 comment added username The altitude of the plane is clearly negligible. No more than 10km, compared to 36 000 km for the satellite: less than 0.03%. You can mollify it by the curvature of the earth, but considering where the satellite is compared to the plane, the altitude still does not matter much. To get the pings 'en route' they had to remove all other pings, I guess

Mar 25, 2014 at 7:59 comment added Neil Strickland I suspect that there is no very simple story here. If I understand correctly, the pings were infrequent, and none was received by more than one satellite. I have not seen any clear statement of what data was logged by Inmarsat, which is crucial to understand the possible methods. Reports suggest that the Doppler effect was used somehow, so they must have some kind of frequency data. I also read that Inmarsat built a complex model based on a large dataset of pings from other flights an "did a couple of years worth of research in two weeks".
Mar 25, 2014 at 7:52 comment added Alex Becker Keep in mind that ping times are probably a very unreliable method of determining distance; they are probably intended for measuring network latency, so incorporate unpredictable delays in processing on both the plane and satellite's ends.
