Abstract

ADS-B is a new type of ATC system based on GNSS. As the aircraft in the route is a 3D target, the 3D coordinates of the location information is very important, positioning accuracy directly affects the ADS-B system reliability and efficiency. In this paper, various error models are established, and the Positioning effect of ADS-B static and dynamic targets are analyzed. The simulation results can only reflect the errors of ADS-B to some extent. In addition, the simulation does not take into account the delay of UAT data chain. The errors in the delay time, especially in the course direction, are bigger than the simulation result, which can be eliminated or weakened by the method of track prediction. Elevation information is calculated from the barometric altimeter in the real system with greater error.
