    Re: Do We Still Need to Use Sextants?

    I would like to see at least 1' accuracy, and would feel better if it was closer to 0.3' (18") as modern Celnav tables and techniques can allow for this kind of accuracy.

    As far as the vertical is concerned, that is where the navigator comes in. Any solution to find this via machine will be very expensive.

    I like Greg's idea of visual ID. If the computer can read the arc this via webcam to the accuracy and precision of the sextant, we are in good shape.

    This idea fits in well with the ECDIS idea where the speed of acquisition and accuracy of the LOP's are the primary concern. I am looking for ways to avoid pulling out tables and plotting sheets that then have to be manually transferred to the ECDIS. This would not be a replacement for traditional CelNav techniques.
