Location systems and methods are operable to determine a location of an airborne vehicle. An exemplary embodiment identifies at least one object in a pre-captured image (202) stored in an onboard memory (116) and defined by a known location, identifies at least one ground object in a current radar image (302), correlates the ground object identified in the current radar image (302) with the object identified in the pre-captured image (202), determines relative location between the installation vehicle and the identified object in the pre-captured image (202), and determines the location of the installation vehicle based upon the known location of the identified object in the pre-captured image (202) and the determined rel ati ve location.
