    摘要: The present invention relates generally to a method and system (10) for classifying vehicle behaviour, particularly abnormal behaviour of civil aircraft (12). The method may comprise receiving aircraft data from an aircraft (12) which is to be classified; and determining whether the received aircraft data comprises identification information for the aircraft (12). In response to a determination that the received aircraft data comprises identification information, the method may comprise using said identification information to classify the behaviour of the aircraft (12). In response to a determination that the received aircraft data does not comprises identification information, the method may comprise obtaining the position of the aircraft and comparing the obtained position to an expected route for the aircraft to classify the behaviour of the aircraft (12).

    摘要: A method and system for positioning a vehicle in relation to each moving target of an ordered set of moving targets. Each of the moving targets moves from an initial position at a constant velocity. Embodiments can compute an estimated time for the vehicle to be positioned within a predetermined proximity of one of the moving targets; compute an estimated location of the moving target at the estimated time, based on a current position of the moving target and the constant velocity of the moving target, and compute a required velocity for the vehicle to move from its current position to reach the estimated location by the estimated time. If the required velocity is less than or equal to a maximum velocity of the vehicle, outputting the estimated time and the estimated location for use in positioning the vehicle.

    摘要: A profiling approach for determining a path for an aircraft, using a method comprising the steps of determining at least two waypoints between a starting position and a desired terminal position for the aircraft, determining a path for the aircraft between the starting position and the terminal position, by performing a linear approximation of the heights of the waypoints such that the average height change between waypoints is minimized, and constrained by a maximum climb angle of said aircraft, and performing a linear approximation of arrival times for each of the waypoints and aircraft speeds between the waypoints, constrained by permissible velocity of said aircraft on the slope between the waypoints. In this way, the non-linear relationship between climb rate and speed is approximated with linear equations, because determination of the path between each set of two waypoints is broken into two linear problems.

In this way, the non-linear relationship between climb rate and speed is approximated with linear equations, because determination of the path between each set of two waypoints is broken into two linear problems.

    摘要: A system and method of positioning a set of vehicles (102) with respect to an object (104) and a set of targets (106). Embodiments can generate (302) an isovist using data obtained from at least one sensor associated with the object and use it to compute (304) an estimated position of each target with respect to the object. Embodiments can compute (306) a plurality of positions for each vehicle based on the estimated positions of the targets, with each position having an associated value representing a number of the targets at their estimated positions that are within a predetermined proximity of the vehicle at that position. Embodiments can select (308) a subset of the positions based on the associated values, and position (310) the set of vehicles based on the selected subset of the positions.

    摘要: A method and apparatus for determining actions for entities (4, 6) such that a goal is accomplished constraints are satisfied. The method comprises: determining an initial plan comprising actions that, if performed by the entities (4, 6), the goal would be accomplished; determining that a constraint would not be satisfied if the initial plan was implemented; and iteratively performing steps (i) to (v) until a final plan that accomplishes the goal and satisfies the is determined. Step (i) comprises identifying a constraint that is not satisfied in part of the current plan. Step (ii) comprises determining a remedy that, if implemented, satisfies the identified constraint. Step (iii) comprises updating the goal specification to include the remedy. Step (iv) comprises, using the updated goal specification, determining a further plan that accomplishes the goal and the remedy. Step (v) comprises determining whether or not the further plan satisfies each constraint.

    摘要: Disclosed are methods and apparatus for determining a path (4) for a vehicle (2). The method comprises providing starting and final positions for the vehicle (2), and using the provided positions, determining an ordered sequence of points, thereby providing the path (4) for the vehicle (2). Performing the optimisation process comprises: minimising a distance between the final position and a last point in the sequence; for each point other than a last point in the sequence, constraining a distance between that point and the next point to be equal to a predefined distance; and, for each path point other than the first and last points, constraining an angle between a line that connects that point to the point that precedes it and a line that connects that point to the next point to be greater than or equal to a predefined angle.
