    Photographic sextants

    With the recent postings concerning Bris sextants in mind, I came across a paper written many years ago about a proposed camera-based navigation system for a earth orbiting or moon-bound spacecraft. This was many years before the advent of digital cameras, and the proposed system used film, which they assume could be developed quickly enough on board to be useful (!). Most of this goes strait over my head, but I'm assuming there are quite a few of you out there that this would be of use to, especially since digital technology would allow you to automate the data reduction.
