Aiming to reduce the uncertainty of the trajectory of Continuous Descent Operations (CDO) in high-density airspace, this paper combines the unscented transformation and Kalman filtering, and a dynamic flight trajectory prediction algorithm based on Unscented Kalman Filter (UKF) is proposed. Firstly, according to the real-time ADS-B data, the position and speed of the aircraft are converted. Then, to improve the prediction accuracy of the dynamic flight trajectory, the aircraft state equations are processed by unscented transformation, and a dynamic trajectory prediction model based on UKF is established. Finally, taking the CES2492 flight as an example, a fast-time simulation is carried out, and the results are compared with those obtained by the traditional Kalman filter and the extended Kalman filter. The simulation results show that the method proposed in this paper can improve the filtering effect and effectively enhance the trajectory prediction accuracy.
