    No Two-Body Fix Problems
    From: John Karl
    Date: 2009 Nov 5, 09:35 -0800

    I'm starting a new thread (I think it's called) because the "Two Body
    Fix Caveat" seems to have gotten off topic.
    
    As I posted on the other thread, It seems to me that if the computer
    code simply calculates the answers for the two possibles fixes, using A
    +B and A-B in Eq. 7.5d, and then lets the navigator pick the closest
    fix, all possible combinations of the locations of the GPs and ship
    are covered.
    
    And I don't see any problem with the ship being on, or near, GP1's
    meridian.  This is a well defined problem with no ambiguity in the
    equations, and the navigator doesn't need to know his position
    relative to the meridian.
    
    Computing both fixes makes the program's inputs and outputs very
    logical and straightforward.  After all, there are two fixes in the
    solution and the navigator must, indeed, select the proper one.
    
    Those interested might want to check this out to see if I'm right,
    
    John
