Abstract : This project explores the feasibility of using a small, general digital processor, with an optical sensor and a clock, as a means to autonomously determine location. A stellar pattern-recognition algorithm is presented that determines the identity of any of the navigation stars catalogued in the U.S. Naval Observatory 'Air Almanac' which may be in the sensor's field of view. Appendices describe an iterative method for determining position on the surface of the earth from celestial observations without using azimuth information, and a mechanism for determining relative position in deep space.
