    摘要: Disclosed is a system and method for determining the runway configuration of an airport. The method may include retrieving recorded surveillance data including instances of aircraft positions at an airport; determining a plurality of three-dimensional surveillance cells at each end of one or more runways of the airport; computing a count of the number of aircraft positions within each surveillance cell; and determining a current configuration for each runway based on the count computed for the surveillance cells of the runway. The predicted runway configuration of the airport can be used for updating the flight plan of an aircraft to reduce the total flight duration and minimize fuel consumption.

    摘要: System and method to protect the privacy of ADS-B messages transmitted by aircraft. The system includes one or more ground stations with a ground station control unit and a ground ADS-B transponder for receiving an ADS-B message. The ground station control unit includes an aircraft position determination module for retrieving an aircraft position included in the ADS-B message; an operating conditions module for determining the fulfillment of operating conditions including determining if the aircraft position is an actual aircraft position; and a fake aircraft position generator for computing one or more fake aircraft positions. The ground station control unit broadcasts one or more fake ADS-B messages including the fake aircraft positions if the operating conditions are met. With this system only trusted receivers can obtain the real position of the aircraft.

    摘要: A method for policy-based traffic encounter assessment to detect and avoid traffic includes determining, by a processor, an ownship predicted trajectory of an aircraft. The aircraft is the ownship. The method also includes determining a traffic predicted trajectory of one or more other aircraft in the vicinity of the ownship. The one or more other aircraft includes traffic. The method also includes assessing an encounter between the ownship and the traffic, wherein assessing the encounter between the ownship and the traffic includes applying an encounter assessment policy to the traffic predicted trajectory and the ownship predicted trajectory. The method further includes generating encounter assessment data in response to assessing the encounter between the ownship and the traffic. The encounter assessment data is used to at least detect and avoid the traffic by the ownship.

    摘要: A system and a computer-implemented method for evaluating uncertainty of a predicted trajectory infrastructure is disclosed The method comprises collecting a plurality of data sets from a predicted trajectory: comprising providing an aircraft intent description based on the predicted trajectory; selecting both a point in time and one or more variables among the collected plurality of data sets as sources of uncertainty; representing each selected variable at the selected point in time as a uni-variable polynomial expansion; representing each non-selected variable by a single point; and combining selected and non-selected variables into a multi-variable polynomial chaos expansion representing a stochastic prediction of the aircraft's trajectory at the selected point in time and a measurement of a sensitivity of the prediction to each of the selected one or more sources of uncertainty.

    摘要: And aircraft recharging station is provided for recharging an aircraft provided with a rechargeable battery. The recharging station includes a parking surface with conductive tiles selectively connected to an electrical power supply. The recharging station also includes a controller configured to determine a position of the aircraft on the parking surface by connecting, including being configured to iteratively connect a different pair of tiles to the electrical power supply to provide a circuit including positive and negative tiles connected thereto, and test an electrical circuit condition of the circuit, until a closed circuit condition is determined, thereby indicating that the aircraft is positioned on the positive and negative tiles, and that the battery is thereby rechargeable by the electrical power supply.
