1. A system for creating a digital representation of a status of one or more air vehicles and of sensed external objects, the system comprising: one or more sensors configured to be coupled to each of the one or more air vehicles; and a processor associated with the one or more sensors and configured to: determine navigation information associated with travel of at least one of the one or more air vehicles; capture data associated with the sensed external objects sensed by the one or more sensors during travel of the one or more air vehicles, the sensed external objects comprising terrain features and sensed signals; identify and track the sensed external objects in the captured data; geo-locate the identified sensed external objects via dynamic landmarking; dynamically update a landmark database, the landmark database comprising at least two or more of positional data associated with travel of each of the one or more air vehicles and the sensed external objects based on the determined navigation information and the dynamic landmarking, covariance of the positional data, and sensor signal snippets of the sensed external objects; and utilize the landmark database to control at least one or more functions in a respective air vehicle of the one or more air vehicles, wherein one of the functions in the at least one or more functions comprises navigating the respective air vehicle based on the positional data in the absence of availability to the respective air vehicle of a global positioning system and generating stabilizing gimbal commands for a payload control system based on imagery feedback, and wherein the imagery feedback comprises an air vehicle's movement obtained via tracking of images of terrain features and image processing.
