4D trajectory estimation based on nominal flight profile extracting and airway meteorological forecast revising

□ A method of extracting the nominal flight profile based on AMDAR data is proposed, including nominal flight altitude profile extracting by DSW distance algorithm and nominal airspeed profile extracting by CAS/TAS conversion model. The extracted profile contains flight and air traffic control intentions. □ An airway meteorological forecasts revising model is built, in which the meteorological observations acquired by reference aircraft can be used to revise those meteorological forecasts related to object aircraft according by Cressman interpolation. The model can improve the improve the accuracy for 4D trajectory estimation. □ Future work shall use multiple data fusion such as Automatic Dependent Surveillance-Broadcast (ADS-B) data and Quick Access Recorder (QAR) to overcome the defect of AMDAR in time and space limitations.
