Systems, methods, and apparatus for identifying and tracking UAVs including a plurality of sensors operatively connected over a network to a configuration of software and/or hardware. Generally, the plurality of sensors monitors a particular environment and transmits the sensor data to the configuration of software and/or hardware. The data from each individual sensor can be directed towards a process configured to best determine if a UAV is present or approaching the monitored environment. Radar sensors included in the plurality of sensors may identify specific locations corresponding to objects in an airspace, and video sensors such as PTZ cameras may be directed to collect image data of the objects at the specific locations for identifying the objects as UAVs and tracking the UAVs. The system predicts next locations for the UAVs and directs the PTZ cameras to update their orientations for following the UAVs.

Disclosed here are system, apparatus, article of manufacture, method and/or computer program product embodiments for track association. An embodiment operates by receiving a first set of track identification data from a first tracking system. The first set of track identification data is associated with a global track identifier (GID). The first set of track identification data associated with the GID is broadcasted to the first tracking system and a second tracking system. A second set of track identification data is received from the second tracking system. The second set of track identification data identifies any tracks of the second tracking system that match the first set of track identification data. The GID is associated with the second set of track identification data.

A device comprising a radar for taking at least one radar image of the terrain in front of the aircraft in a zone containing at least one characteristic pattern, the position of the characteristic pattern being known, an image processing unit for detecting, on the radar image taken by the radar, a characteristic symbol representing the characteristic pattern, a computation unit for determining, from at least the position of the characteristic symbol in the image and from characteristics of the radar image acquisition, relative position information illustrating the position of the aircraft in relation to the characteristic pattern, and for determining the position of the aircraft, from the relative position information and from the known position of the characteristic pattern, and a unit for transmitting at least the position of the aircraft to at least one user system, for example a landing aiding system or an SVS display.

A waveguide device includes: an electrically conductive member having an electrically conductive surface; a waveguide member having an electrically-conductive waveguide face of a stripe shape opposing the electrically conductive surface, the waveguide member extending along the electrically conductive surface; and an artificial magnetic conductor extending on both sides of the waveguide member. The waveguide member has a bend at which the direction that the waveguide member extends changes. A waveguide which is defined by the electrically conductive surface, the waveguide face, and the artificial magnetic conductor includes a gap enlargement where a gap between the electrically conductive surface and the waveguide face is locally increased. In a perspective view along a direction perpendicular to the electrically conductive surface, at least a portion of the bend has an overlap with the gap enlargement.

Higher-resolution imagery of an airport runway can be provided from the pilot's point of view. Pilot point of view images may be generated using images captured by higher-resolution ground-based cameras. The images from the ground-based cameras are fed to a point of view processor that generates the pilot point of view images using aircraft position information. The pilot point of view images are transmitted to a display on the aircraft.

Systems and methods are disclosed for predicting a hot spot. One method comprises receiving, by a hot spot prediction system, vehicle characteristics associated with a vehicle and traffic data. Then the hot spot prediction system determines a hot spot and an estimated arrival time at the hot spot based on the vehicle characteristics and the traffic data. Following the determination, an auto brake application system receives the hot spot and the estimated arrival time and determines a safe stop time based on the vehicle characteristics, the hot spot and the estimated arrival time. The auto brake application system then sends a notification to the vehicle based on determining that the vehicle can stop within the safe stop time, and performs an action in response to receiving a confirmation from the vehicle.

A system for extracting a ground route of an aircraft includes an airport surface detector acquiring ground movement information of an aircraft detected in an airport, a mapper acquiring node information of the airport from a database and mapping the ground movement information with the node information, a route detector detecting taxi route information of the aircraft by collecting adjacent node information of a mapped coordinate and erasing redundant node information among collected adjacent node information, a node identifier identifying start node information or end node information of a taxi route by using stand node information of the aircraft, and a final route extractor extracting a final taxi route including an extracted shortest route by dividing the taxi route into a plurality of sub-routes and applying a shortest route algorithm to the divided sub-routes.

A test method in operational phase includes three distinct steps, a first step using the replies of the transponder to the interrogations in the Mode S transmitted in operational mode by the secondary radar to perform the measurement of the power of the transponder, and the measurement of the average rate of reply to the interrogations in Mode S transmitted by the radar intended for it; a second step which performs the measurement of the sensitivity of the transponder and a third step which carries out the test of its maximum rate of reply. The second step and the third step are carried out by modifying the operating parameters of the radar so that the additional interrogations required for the measurement can be performed, during the time interval following the last operational interrogation during which the aircraft remains located within the main Sum channel lobe of the antenna of the radar.

A method of detecting collisions between an equipped mobile object travelling around an airport installation and at least one obstacle. The method comprises the following steps. Determining the real-time positions of the equipped mobile object in a reference frame tied to the airport installation. Reading at least one item of information contained in at least one marker fixed to the equipped mobile object. Determining an outline of the equipped mobile object on the basis of the read item of information contained in the marker. Positioning the outline determined in the reference frame tied to the airport installation. Triggering an alert if the distance between the outline of the equipped mobile object and the obstacle is less than a given threshold.
