Abstract:

In order to improve the accuracy of the aircraft monitoring,and to obtain the accurate flight track,ADS-B track correction approach based on basic fight model is put forward to solve the problem of abnormal track in ADS-B monitoring process. The algorithm makes full use of ADS-B flight data information and establishes the flight calculation model and trajectory identification model. Finally the feasibility of the algorithm is validated by using real data. The result shows that this method can accurately and fast correct the track information in level flight,turning and climbing process;meanwhile,it can effectively improve the accuracy of the flight track monitoring.

Key words: monitoring, ADB-B, basic flight model, trajectory correction
