Malaysian airliner’s path ultimately tracked by satellite pings’ Doppler shift

Thanks to data from a satellite communications provider, we now have a clear picture of Malaysian Airlines flight 370’s tragic final destination, plus or minus 100 miles. Unfortunately, that position is at the bottom of the Southern Indian Ocean. Using a scientific model based on the Doppler shift in signals from MH377 (another Malaysian Airlines’ flight) and other aircraft following similar routes, engineers at Inmarsat were able to narrow the area of search for the missing aircraft to an area in the Indian ocean west of Perth, Australia.
