Large-scale four-dimensional flight path dynamics prediction method and device

Abstract

The invention discloses a large-scale four-dimensional flight path dynamics prediction method and device, and belongs to the technical field of aerospace. The device comprises an information obtainingmodule, a data pre-processing module, a track clustering module, a dynamic data access module, an identification and prediction module, and a result feedback module. The information obtaining modulesamples aviation data to constitute flight path sequences. The data pre-processing module removes noise points on each flight path sequence and re-samples the flight path sequences without the noise points. The track clustering module is used for clustering the flight path sequences. The dynamic data access module accesses real-time data, to obtain a four-dimensional vector at equal time intervalsto form flight path sequences. The identification and prediction module recognizes the abnormal flight mode and carries out trajectory prediction. The result feedback module reports the real-time flight path prediction and abnormal recognition conditions to the air traffic management department to guide flight operation in the airspace. Airspace smooth and safe operation is achieved, and great importance is achieved.
