Jon,
Yes, I took a RTT = 600ms as a worst case figure. This is probably a few
10's ms above actual, but I would rather be pessimistic in this instance
than optimistic. That gives the opposition one less bullet for their
anti-satellite gun.

Hi,
Please excuse a newbie question, but where does the 0.6 derive from in
these calcs? Is it the latency introduce by the trip up and back to the
satellite? If so it seems rather high, my calcs give me more like 250ms.
Puzzled,
