Embodiment example

[0135] Select the flight using the VMB-13G standard instrument approach route at Shanghai Pudong International Airport as the simulation object. When the four-dimensional predicted trajectory position error or altitude error exceeds the set threshold, the aircraft's intention information is updated and the four-dimensional trajectory prediction, Figure 11 It is a schematic diagram of the horizontal trajectory of aircraft dynamic trajectory prediction, in which the gray solid line is the boundary of the terminal airspace control sector, the gray dotted circle line is the standard instrument approach route, the black dotted line is the actual trajectory of the aircraft, and the black solid line is the aircraft's predicted trajectory. trace.

[0136] In Figure (a), the black dotted line is the actual trajectory of the aircraft, and the black solid line is the first four-dimensional trajectory prediction. It can be seen from the figure that the predicted trajectory is along the s...

Abstract

The invention provides a four-dimensional flight track dynamic prediction method based on ADS-B information updating. By communicating with networks among ADS-B receivers, a ADS-B data decoding module is adopted to obtain real-time velocity information, height information, longitude information and latitude information of a flight, and consistency check is conducted on a predicted flight track and the real-time velocity, height, longitude and latitude of the flight, so that the dynamic, online and real-time flight track prediction capability is achieved. The method can provide important technical support for developing the automation and intellectualization of air traffic control and achieving the flight-track-based operation.

Description

technical field [0001] The invention belongs to the technical field of civil aviation air traffic management, and in particular relates to air traffic service, automation and intelligence of air traffic control, track-based operation, design and verification of air traffic control decision support tools, and the like. Background technique [0002] In recent years, with the continuous surge of air traffic volume, the operating capacity of the existing air navigation system is almost saturated, resulting in frequent occurrence of airspace congestion, flight delays and other problems, especially in my country. How to improve the efficiency of air traffic operation and ensure the punctuality rate of flights has become an urgent need for the sustainable development of my country's civil aviation transportation under the condition of continuous growth of flight traffic. [0003] The International Civil Aviation Organization (ICAO) proposed the "Aviation System Block Upgrade" (ASBU...
