Deep Space Network stations or other applications (VLBI) where the
measurement uncertainty is like ADEV = 1E-12 in 1000 seconds. There's a
whole analysis of the temperature effects on the fiber optic
distribution components, for instance - and they're buried 2 meters down.
At "billions of dollars in 1960/1970" I think DSN fits in Bob's high
cost/low volume bucket.
