Investigators knew that the satellite’s temperature distorts the way it
receives radio waves. The investigators analyzed changes in the temperature
of the Inmarsat satellite on each occasion that the plane made contact and
then made a calculation about how fast the jet was traveling, according to
Warren Truss, Australia’s deputy prime minister. They compared the data
with the speeds of other aircraft traveling around the time Flight 370
disappeared and communicating with the same satellite. They also
incorporated aircraft performance calculations from Boeing to fix the sweet
spot, Mr. Dolan said. | w********s

evaluating data from hundreds of other flights with similar equipment that
crisscrossed the same region, according to Inmarsat officials. That
established a baseline to better calculate where Flight 370 was presumed to
have gone down.
“The Inmarsat model was designed for fine tuning,” said Inmarsat Senior
Vice President Chris McLaughlin, who said it revised the search area
continually as new information arrived. |
