Thanks James7, interesting article indeed.
Presumably the dotted red line produced by Exner with the newly calculated satellite-to-plane shifts could be used to produce potential flight paths in the same way that Inmarsat used their assessed BFO values to produce the northern and southern ping arcs? Anyone?
The only fly in the ointment is Inmarsat's statement that their interpretation was validated by comparison with data from other flights pinging the same satellite.
