ABSTRACT:
A method and system for determining three-axis attitude from line-of-sight (LOS) solutions for two or more GPS satellites uses intersections of null cone patterns and LOS vectors to the GPS satellites. In a preferred embodiment, a unified GPS-based sensor also provides navigation information.
