Hi Armando et al,

I don't know about the methods written up by Karl & James. For a long time 
I've had a project using Doppler shift curves in the back of my mind 
(the "target" doesn't need to cooperate). I have most of the hardware based 
around my HPSDR box and a t'bolt frequency reference. The software hasn't 
even progressed beyond ideas and algorithms. I haven't even picked a language 
or development environment (one day).

I can see a very accurate Doppler shift curve being useful in the early days 
after a multiple cubesat launch. How accurate would you need to be to 
pick "your" cubesat from the crowd? One pass? multiple passes?

Anyway that's this morning's breakfast coffee ideas from me. Have fun 
y'all :-).
