Britain's Inmarsat used a wave phenomenon discovered in the nineteenth century to analyse the seven pings its satellite picked up from Malaysia Airlines Flight MH370 to determine its final destination.

The findings led Malaysian PM Najib Razak to conclude that the Boeing 777 crashed thousands of miles away in the southern Indian Ocean, killing all 239 people on board.

This map shows the possible routes taken by flight MH370 if it was moving at constant speeds of 400 knot (740km/h) and 450 knot (833km/h) respectively.

An infographic illustrating the Doppler effect

This graph released by the Malaysian authorities shows the following: The blue line is the burst frequency offset measured at the ground station for MH370, the green line is the predicted burst frequency offset for the southern route, which over the last 6 handshakes show close correlation with the measured values for MH370. The red line is the predicted burst frequency offset for the northern route, which over the last 6 handshakes does not correlate with the measured values for MH370.

British firm Inmarsat developed a new technique which analyses the speed of the aircraft relative to the satellite.
