No, but they compared the present data with recorded data from other flights along the same routes for comparison.
- waterlesscloud 13y agoWell, there wouldn't be flights along the Southern route, exactly, since it led nowhere. So I'm guessing they extrapolated from routes that were in that general direction, like Sri Lanka - Perth. It's likely there's a lot of assumptions at work in their calculations, but it might be good enough.

- lutusp 13y agoI should have been more clear -- they compared routes and aircraft velocities that could be expected to produce the same radial velocity and Doppler effects, given the satellite's geostationary position.
