Inmarsat Senior Vice President Chris McLaughlin said that on Monday, March 10, it began extrapolating the location of the jetliner using the aircraft's changing angle and distance to the satellite, which orbits more than 22,000 miles above a point in the Indian Ocean.
Mr. McLaughlin said the data was shared the following day with SITA, which in turn shared it with Malaysian officials.
At that point, the search was still focused primarily in waters east of the Malay Peninsula, and Malaysian officials hadn't confirmed reports that Flight 370 had altered its course to Beijing about an hour after takeoff to fly west across the peninsula.
Inmarsat's package showed not only that the plane had continued flying for hours, but that it had made an even more radical course change later, ending up along one of two possible corridors, one heading northwest toward Kazakhstan and the other curving far south over the Indian Ocean.
The Inmarsat package, which included a map of the twin north and south corridors, together with readouts of data from a communication satellite, demonstrated the need for a dramatic shift in search areas, according to people briefed on the investigation.
