    Replace the stars and planets with satellites and you have a GPS?

    I would like an electronic sextant that you would sight the heavenly body without ever trying to see the horizon.

    If it had a built in electronic plumb bob, it could record the angle between level and the sight crosshairs.

    Add a watch and a trigger to mark a sight.

    So...  you would line up the crosshair on the bottom of the sun, hold a button that would display the time and angle for when you pushed the button.

    This would be equivalant to a sextant and nothing more; just way easier to use and useful more often.

    Once this was working, I'd go for a reset button.  Then you would push the reset button, line up the body and press the trigger for several successive

    measurements.  These would be close fitted to give a good reading.

    On the deluxe model, I'd add an interface to a computer, and a built in compass plus the ability to record multiple bodies in one session on deck.

    Throw in a separate PC software application that processes the downloaded data to produce a fix.

    The one thing I wouldn't do is try to design what the military is asking for.  All of us together wouldn't have the money needed to keep up with the things they would keep adding to their request.
