This technical report describes the Passive Navigation study, an investigation to determine if a small, low-flying aircraft can be navigated using passively sensed images of the ground. The system described uses a position determination concept based on motion stereo i.e., a stereo pair derived from a single camera sensing the scene at two different points on the flight path. A bootstrapping approach to position determination has been developed that starts with a set of known ground points and projects points forward from frame to frame. This stereo bootstrapping system forms the major portion of the system, and was a major portion of the study.
