For the past two years a study of the navigation of a small, low flying vehicle based on passively sensed imagery has been carried out. The dead reckoning is based on motion stereo, with corrections made periodically based on analysis of landmarks found in images. Because the landmark subsystem requires a database of knowledge concerning salient features of the region, it is natural to consider extension of the database to include data relevant to target cueing. This paper describes the passive navigation system and then discusses the role of the database for target cueing. Preliminary findings using this concept are described.
