    Re: 2-Body Fix -- take three
    From: John Karl

    George, and others who may be interested --
    
    Remember we navigators are sensitive to terminology (negative
    longitudes, assumed positions, dip, index mirrors, etc.).  So please
    don't call the two fixes "ambiguous" in the 2-body problem.  The key
    point that everyone needs to agree on is, that, given only the
    altitudes of two bodies and their coordinates, there are TWO
    UNAMBIGUOUS fixes.  Other than outside information, no computer code,
    no reformulation of the equations, can distinguish between these two
    fixes.  Does anyone on the List disagree with that??  If so, tell me
    where I'm going astray.
    
    And Frank --
    
    You may have not have found any student confused by the concept of
    assumed position.  But just try asking any CN navigator why we use an
    assumed position in the intercept method, and I'll bet you'll find
    that at least 98% of them respond with a misconception.  Of course, I
    may be wrong; I'm only by going by all the CN books I've read.  Then
    again, as a CN navigator, I may be a bit too sensitive.
