    How Many Chronometers?
    From: Greg Rudzinski
    Date: 2009 May 6, 10:10 -0700

         When a time tick or other master reference is not available then
    by what means can a navigator at sea use to determine whether a
    chronometer is maintaining a consistent rate. If two chronometers are
    carried then an inconsistency between the two would suggest a problem
    but then which chronometer is at fault? How about a third chronometer
    to help the navigator determine which chronometer is behaving badly.
    Carrying three chronometers does triple the chances of one going down
    but since quartz watches are cheap why not carry three?
    
    Greg
