The Search for MH370 — Journal of Navigation
Ashton, Dickinson, Hall, Roberts, Smith · Inmarsat · 2014/15
The paper that showed how BTO and BFO from routine signalling units can reconstruct a long flight the airline did not know it still had.
Inmarsat engineers published the method behind the 15 March 2014 announcement: burst timing offset as a range constraint, burst frequency offset as a Doppler/velocity constraint, and the resulting north-versus-south discrimination. The paper is the reason a communications company, not a radar site, became the principal witness to the last six hours. Subsequent ATSB/DSTG work sits on this foundation. The paper does not claim a wreckage coordinate.
