Abstract
Navigational systems and methods are disclosed herein to provide accurate processing of two-dimensional sensor images for navigation and determination of position in three-dimensions. Landmark features are extracted from two-dimensional sensor images and correlated to landmark features data stored in a database to estimate latitude, longitude, and altitude of a vehicle or missile.
