30 ns seems a little closer than most radio site applications need...
what drives this requirement?
Ordinarily you could throw in an
appropriate GPSDO and be done with it. However, we also have the
reqirement to be able to operate independent of GPS for up to six days.
Wow, ok, and what drives *that* requirement? Can you use any other
mutually visible thing, or do we assume all satellites have vanished
from orbit?
