Washington Post tracks Inmarsat role in hunt for MH370

Inmarsat’s role in the search for Malaysia Airlines flight MH370 began immediately after the aircraft disappeared, The Washington Post has reported.

Based on a series of hourly ‘handshakes’ received by one of Inmarsat’s satellites from the plane, Inmarsat calculated that the aircraft had flown along one of two routes – one arcing north and the other south – 24 hours after it vanished, said the newspaper.

The report added that the handshakes from the satellite – along with assumptions about the plane’s speed – helped Australia and the US National Transportation Safety Board to narrow down the search area to just 3 per cent of the southern corridor on 18 March.
