Airplane Trajectory Data Processing with Actual Weather Data

Nowadays accurate airplane trajectory data are available with various open databases. Commercial networks of ground-based receivers of data transferred under automatic dependent surveillance-broadcast (ADS-B) have wide coverage and support most continental airspace. ADS-B trajectory data is non-synchronized in time and includes only coordinates of airplane location and pressure altitude. In the paper, we consider primary data processing with A-B-G filter and recovery parameters of airplane trajectory. A-B-G filter is one of the most frequently used tracking filters for effective noise reduction and data recovery. We recover ground speed, vertical speed, true heading angle, and pitch angle. Also, we use data of actual weather distribution along airplane trajectory to estimate airspeed and sideslip angle. In a numerical demonstration, real air traffic data has been used in the recovery process to study parameter distribution over the airplane flight trajectory. Recovered parameters could be useful for different safety studies and visualization in flight simulators.
