"Resolving round trip time to a billionth of a second gives a theoretical accuracy of 0.1mm"

You sure?

Speed of light in air = 3.10^9 m/s

Divide by 1.10^9 = 3.1m

That's a round trip so can resolve to half that, so ~1.5m.

Having said that resolving to 1nS isn't much to boast about, is that correct?
