A method for determining the trajectory of at least one mobile element from position data, includes an initial step consisting in classifying a set of positions relating to at least one detected mobile element by applying a first data classification algorithm to the set of positions, which provides an initial trajectory relating to each detected mobile element. The method comprises the following steps, implemented on each current observation window: classifying each new position detected in at least one trajectory by applying a second data classification algorithm; identifying, for each detected mobile element, the positions relating to the detected mobile element; determining an intermediate complete trajectory for each detected mobile element; determining a final complete trajectory for each detected mobile element.

A method for supervising an air traffic tracking system that includes determining performance indicator values and an operating feature of the tracking system for the current situation on the basis of the performance indicator values; if the operating feature is representative of an operating abnormality of the tracking system, determining at least one performance indicator corresponding to the operating abnormality, and determining values of the at least one performance indicator corresponding to normal operation; determining at least one quality of service measure of the tracking system based on the performance indicator values; if the at least one quality of service measure is representative of a degradation in the quality of service, determining at least one performance indicator corresponding to the degradation in the quality of service; executing at least one evaluation process associated with the at least one performance indicator and/or to the degradation in the quality of service.

A multiple-sensor tracking method, notably implemented in an air traffic control system, making it possible to reduce the latency time introduced by the tracking system, characterized in that the correlation () and association () functions work on the basis of membership of the detections () and of the tracks () to cells () defining a subdivision into a grid () of the surveillance area represented on a stereographic projection plane.
