Embodiment Construction

[0022] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0023] refer to figure 1 , a method for monitoring aircraft routes based on ADS-B broadcast signals, comprising:

[0024] S101. Divide the selected route into multiple route segments, and obtain multiple optimal stations for each route segment.

[0025] In one embodiment, the airway is divided into a plurality of airway segments by slicing.

[0026] The aircraft route may be irregular, so the position of the station receiving the aircraft signal has a great influence on the positioning of the aircraft route. Divide a determined irregular air route into regular small air route segments, and each small air route segment is approximately regular. In addition, the smaller the route segment, t...

Abstract

A method, a device and a computer storage medium for monitoring an aircraft route based on an ADS‑B broadcast signal. The method includes: the selected route is divided into multiple route segments, and obtains a plurality of optimal sites of each route segment; receives the ADS‑B broadcast signal of the aircraft through the optimal site, and obtains a plurality of optimal sites of the aircraft. measurement information, wherein the measurement information at least includes the required arrival time difference and angle of arrival of the aircraft; positioning the aircraft according to the measurement information, and obtaining first position information of the aircraft; combining the first position information with According to the comparison of the second position information of the aircraft acquired by the ADS‑B broadcast signal, when the error between the two exceeds the preset threshold, a prompt message is issued. This solution improves positioning accuracy and robustness, and effectively solves the problem that ADS‑B broadcast signals are easily tampered and attacked, and can effectively guarantee the reliability of route positioning.

Description

technical field [0001] The invention belongs to the field of aviation monitoring and air traffic management, and in particular relates to a method, a device and a computer storage medium for monitoring an aircraft route based on an ADS-B broadcast signal. Background technique [0002] Traditional route monitoring mainly relies on radar systems, which are not only expensive, but also have insufficient positioning accuracy. With the evolution of aircraft surveillance and air traffic management from radar to ADS-B, the future demand for air-space-ground integrated communication puts forward higher requirements for aircraft route positioning and tracking, and it is necessary to introduce more advanced positioning methods in route scenarios. The ADS-B positioning monitoring system has higher positioning accuracy and lower cost. However, since ADS-B is designed as a broadcast signal, there are cases where ADS-B messages are tampered with and attacked, and there are great problems...
