초록 ▼

A machine-implemented method for detecting and resolving conflict between a plurality of objects on trajectories in space. A two-dimensional representation is generated which depicts the trajectory of one of the objects and the times remaining until conflict of said one object with front and back limiting trajectories, respectively, of at least one other of the objects. An indication of potential conflict is displayed on said representation when the trajectory of said one object is between the front and back limiting trajectories of said other object. The front and back limiting trajectories for each such other object are calculated by enclosing a preselected protected airspace about said one object in an imaginary parallelogram having one set of sides parallel to the trajectory of said one object and the other set of sides parallel to relative velocity of such other object with respect to said one object. The sides parallel to said relative velocity depict the times, respectively, during which said one object will be closest to the protected airspace just touching it from the front and closest to the back of said protected airspace without touching it. Conflict is resolved by diverting said one object by an appropriate maneuver to a conflict-free path in which the trajectory of said one object no longer lies between the front and back limiting trajectories of any other object.

A processor-implemented method of detecting and resolving conflict between a plurality of objects on trajectories in space, comprising the steps of preselecting an airspace of specified shape and size that contains one of said objects and is to be protected from penetration; calculating front and back limiting trajectories for another of said objects by enclosing said protected airspace in an imaginary parallelogram having one set of sides parallel to the trajectory of said one object and the other set of sides parallel to the relative velocity of said other object with respect to said one object; generating an output which indicates the trajectory of said one object and the times remaining until conflict of said cone object with the front and back limiting trajectories, respectively, of said other object; indicating potential conflict when the trajectory of said one object is between the front and back limiting trajectories of said other object; and resolving conflict by diverting said one object by an appropriate maneuver to a conflict-free path in which the trajectory of said one object no longer lies between the front and back limiting trajectories of said other object.
