    Abstract: In some examples, a system includes a transceiver configured to receive surveillance messages from Y target vehicles, where Y is an integer greater than two. The system includes processing circuitry configured to determine predicted positions of the Y target vehicles based on the surveillance messages. The processing circuitry is also configured to determine reported positions of the Y target vehicles based on later received surveillance messages. The processing circuitry is further configured to determine that respective differences between the respective predicted position and the respective reported position for X of the Y target vehicles is greater than a threshold distance. The processing circuitry is configured to determine that Global Navigation Satellite System interference has occurred in response to determining that X divided by Y is greater than a threshold level.

    Abstract: A system for tracking a vehicle includes a transceiver configured to receive a first signal including first surveillance data from the vehicle at a first time, and receive a second signal from the vehicle at a second time. The system further includes processing circuitry configured to determine a first location and a first course of the vehicle at the first time based on the first surveillance data, and determine a change in power level from the first signal to the second signal. The processing circuitry is further configured to predict a maneuver for the vehicle based on the first location, the first course, and the change in power level from the first signal to the second signal.

    Abstract: This disclosure is directed to systems and methods for generating outputs based on collected aircraft maneuver data. In one example, a system is configured to collect surveillance data from one or more aircraft. The system is further configured to identify, from the collected surveillance data, aircraft maneuver data indicative of maneuvers of the one or more aircraft. The system is further configured to store the aircraft maneuver data in a data store. The system is further configured to perform one or more analyses of the stored aircraft maneuver data in the data store. The system is further configured to generate an output based on the one or more analyses of the stored aircraft maneuver data.

    Abstract: A method for detecting noncompliance with aviation regulations and operating procedures is disclosed herein. The method analyzes communication associated with a host aircraft to identify key information, stores the identified key information in a data storage device, and determines whether a particular aviation regulation or operating procedure applies to the host aircraft. After determining that a regulation or operating procedure applies, the stored key information is compared against reference information maintained in a database in association with the regulation or operating procedure. An alert is generated when the comparing detects a discrepancy between the stored key information and the reference information.

    Abstract: An aircraft synthetic vision display system (SVS) includes a topographical database including topographical information relating to an airport, a global positioning system receiver that receives a satellite signal from a global positioning satellite to determine a geographical position of the aircraft, and a ground-based augmentation system receiver that receives a ground-based signal from a ground-based transmitter associated with the airport, wherein the ground-based signal includes geographical information associated with the airport. The SVS further includes a computer processor that retrieves the topographical information from the topographical database based on the geographical position of the aircraft, that retrieves the geographical information associated with the airport, and that corrects the topographical information using the geographical information associated with the airport to generate corrected topographical information. Still further, the SVS includes a display device that renders three-dimensional synthetic imagery of environs of the aircraft based on the corrected topographical information.
