    Re: Fix Maximum Probability Positions
    From: John Karl

    It seems that several of us (or just me) are mired in deep confusion over terminology.

    So I've attached yet another summary (a short one) of the comparison between the estimated-position running fix (EPRF) and the traditional running fix (TRF).

    To avoid confusion between the EP and the DR locations, I introduce a new name, called the tentative point (TP), the one TRF uses for the destination when advancing the first LOP. This TP is simply where we think we are when a new LOP is acquired. For our discussion it doesn't matter how the navigator determined that. But we do consider that it has an uncertainty surrounding it -- what doesn't.

    Please take a look, it's just one figure.
