    Re: Sextant Accuracy and anomalous dip

    Bruce raises the intriguing point that the people who established the
    cable station could get time over the wire to establish its location.
    However, why couldn't the repair ship do the same?  Surely the time of
    the captain and first officer over a half day to a whole day was more
    valuable than a few time transmissions.  I hazard that the delays in
    propagating a signal were unknown enough that accurate time could not
    be transmitted long distance.
    This leads us back to Jared's question, where they did seem to be
    establishing their observatory in a random spot.  However, perhaps it
    wasn't too difficult to measure the distance to a known spot in the
    vicinity, or perhaps the spots were known and had been located by
    observing the moons of Jupiter or some such.
