How British satellite company Inmarsat tracked down MH370 - Telegra
"Malaysian
Prime Minister Najib Razak has announced that, based on satellite data analysis from UK
company Inmarsat, Malayian Airlines flight MH370 ended in the southern Indian Ocean, and
no one on board survived. 'Effectually we looked at the doppler effect, which
is the change in frequency, due to the movement of a satellite in its orbit. What
that then gave us was a predicted path for the northerly route and a predicted
path the southerly route,' explained Chris McLaughlin, senior vice president of
external affairs at Inmarsat. 'What we discovered was a correlation with the
southerly route and not with the northern route after the final turn that the
aircraft made, so we could be as close to certain as anybody could be in that
situation that it went south. Where we then went was to work out where the last
ping was, knowing that the aircraft still had some fuel, but that it would have
run out before the next automated ping. We don't know what speed the aircraft
was flying at, but we assumed about 450 knots.' Inmarsat passed the relevant
analysis to the UK Air Accidents Investigation Branch (AAIB) yesterday. The
cause of the crash remains a mystery.
