Abstract: In one embodiment, a vision aided navigation system comprises: at least one image sensor configured to produce image frames of a surrounding environment; a feature extractor configured to extract at least one image feature from a first image frame; a navigation filter configured to output a navigation solution based navigation data from a navigation device and changes in position of the image feature in the images; a feature tracker to receive the image frames and predict a location of the image feature in a subsequent image frame; a dynamic localized parameter adjuster to adjust at least one image parameter of the subsequent image frame; and wherein the feature tracker is configured so that when the image feature cannot be identified in the subsequent image frame within a bounded region around the predicted location, the dynamic localized parameter adjuster adjusts the at least one image parameter within the bounded region.

Abstract: An air traffic command automation system for automating the process of listening to, interpreting, adhering to, and responding to air traffic command messages is disclosed. The system includes one or more processors configured by programming instructions on non-transient computer readable media. The system is configured to: receive an air traffic command message, from an entity other than the flight crew, that includes one or more tasks for the aircraft to perform; determine from the command message the one or more tasks for the aircraft to perform; generate a sequence of actions for each task that the aircraft can undertake to accomplish the task; verify the coherence, feasibility, and safety of the actions; relay an interpretation of the command message to the command message originator; preview the verified sequence of actions with the flight crew; and issue commands to execute actions at appropriate points during a mission.
