Yes, word is that they were able to determine the Doppler shift in the
plane's signal.  I'm surprised this was even recorded but it must have been
in the satellite's telemetry downlink.   Projecting radial velocity and
constraining it to be close to the earth's surface, I guess determines one
path and the direction on it.

The key they said was getting the doppler shift

I used to work in the telemetry business.  The experts (not me) would be
able to pull information that you'd never think possible from it.
