    Re: LOP's without DR Position
    From: John Karl

    Robin,

    Well, I thought of it myself while I was writing the book.  Since it's a pretty obvious solution to the two-LOP problem, I can't be the first one to write it up.

    The interesting obsevation is that it requires solutions to five equatioins, while computing St. Hilaire for a two-LOP fix requires four solutions of the same type equations, PLUS DRs, straight-line approxmations to the LOPs, and plotting.  So the one extra equation yield a pretty good return...

    And Kermit, Thanks for your note.

    John K.
