What more information are you using besides position, pressure altitude,
and GPS-derived velocity vector to calculate a trajectory prediction?
If adequate information and processing power is available, than it
should not matter in the least whether the prediction is made by the
transmitter or receiver...

If his system is using aircraft performance as well, then for the
trajectory to be calculated by the receiver would either requi

1) aircraft type to be transmitted, and the receiver to have a
database of all possible performance parameters or

2) performance parameters to be transmitted with the other data

Both these have obvious (I think) disadvantages - it makes sense to me
to have th etransmitting aircraft say where it thinks it's going.
