Do I really need that update rate?  If the velocity changes slowly, both 
magnitude and direction, then I can extrapolate.

With access to the drone control signals, I could do a better job of 
predicting the path.

The subject is GPSDO so I doubt if you want to be jerking the control voltage 
around.  Is there any way to take advantage of that?
