Well sure, but I don't know if doppler information between pings buys you much new info.

The pings, as I understand it, came an hour apart, and continued for 7-8 hours total. With just the pings themselves they were able to extract the distance from the sat, which is what led to those arcs they published last week. I dunno if doppler shifts from pings an hour apart add much to that.




If the doppler information can let you say "it was going south, not north" then you can halve the area to just one arc instead of two.


Ok, that makes some sense. Unlike their preliminary calculations, doppler could allow for direction. :-)
