Abstract:

Aiming at the aircraft in route flight phase, the geodetic coordinate system is used to represent the position of the aircraft after comparing the advantages and disadvantages of the space rectangular coordinate system and the geodetic coordinate system. Based on the geodetic coordinate system, the motion of the aircraft is decoupled into independent motion in three directions, and the sub models in each direction are established respectively. The interacting multiple model (IMM) algorithm is used to track the trajectory of the aircraft. The simulation results show that the IMM algorithm based on geodetic coordinate system has good tracking performance for aircraft. According to the aircraft terminal state and the probability distribution of each sub-model, the aircraft's trajectory is short-term extrapolated. The track extrapolation performance of the IMM algorithm based on the geodetic coordinate system is better than that of the IMM algorithm based on the space rectangular coordinate system.

Key words: air traffic management, trajectory tracking, short-term track extrapolation, interacting multiple model (IMM)
