A Kinemetrics/Hassales visit on 16-17.3.1989. We could use
the device 1 day. The time difference between our time and
that of GPS was surprisingly low (500 ns when our second
was brought to GPS, 1200 ns in the other direction. We
measured a separate file in 1 min intervals. A back-up copy
was made of the file.
