1. A method for determining geoposition, comprising: obtaining an image or images of the sky; compiling a list or table of a plurality of stars and their positions in the sky from said image or images; pattern-matching the list or table of said plurality of stars with a predetermined list or table of stars to identify each of said plurality of stars; obtaining first and second light frequencies emitted from each of said plurality of stars in the sky; determining, using a processor, a difference in displacement between the two frequencies for each of said plurality of stars; and correlating a magnitude and direction of said difference in displacement between the two frequencies to determine the geoposition of a body for which a predicted star refraction pattern best-fits measurements relating to the magnitude and direction of said difference in displacement for each of said plurality of stars.
