Abstract: A method of providing a rerouting decision is disclosed. The method includes receiving a flight plan route for a flight between a starting location and a destination location, confirming the flight plan route with an air traffic control system, said flight plan route being associated with a gate at the starting location, receiving at least one candidate reroute of the flight between the starting location and the destination location, and accepting the at least one candidate reroutes of the flight plan prior to leaving the gate at the starting location.

Abstract: A system for exploiting a transmitted signal from an aircraft or drone to determine parameters of the aircraft or drone's motion. The system includes at least one antenna for receiving the transmitted signal from the aircraft, and an analysis system for analyzing the transmitted signal as compared with stored characteristic anomalies associated with any of the aircraft or drone, and the at least one antenna, for confirming parameters of the aircraft or drone's motion.

Abstract: A system is disclosed for exploiting a transmitted signal from an aircraft to determine characteristics of any of the aircraft's motion or meteorological conditions in which the aircraft is moving. The system includes a plurality of platforms for detecting Doppler shift information of the transmitted signal at each of the plurality of platforms, and a processing system for determining characteristics of any of the aircraft's motion or meteorological conditions in which the aircraft is moving.

Abstract: A system is disclosed for providing rerouting information based, in part, on a probability of route acceptance. In accordance with further embodiments, the rerouting information is based, in part, on decision tree analyses involving decisions to request and decisions to not request a reroute.

Abstract: A global airspace surveillance system is disclosed that includes a plurality of satellites that receive weather information from GNSS satellites, and that derive air traffic information from air traffic via satellite antennas directed toward earth's horizon.
