Also having the relative speed to the satellite will help considerably.
I agree, but I can't tell if they have released the necessary data on the satellite position and velocity. If they have, anyone can reproduce the Doppler analysis, which would be reassuring.
In general I accept the concern over crackpot theories, and also understand that Inmarsat has the right to protect its intellectual property, but the more eyeballs looking at the most data possible can only lead to either new interpretations or more confidence in the analysis already done -- either is desirable.
Edt: No satellite position or velocity information in the pdf from Malaysian DCA website. The information can be used to confirm the reasonableness of the analysis, but not confirm it as far as I can tell. It may end up that somebody is needed with knowledge of how "Inmarsat Classic Aero mobile terminals are designed to correct for aircraft Doppler effects on their transmit signals. The terminal type used on
MH370 assumes a stationary satellite at a fixed orbital position."
