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

The invention discloses an ADS-B broadcast signal-based airplane route monitoring method, an ADS-B broadcast signal-based airplane route monitoring device and a computer storage medium. The method comprises the following steps that: a selected air route is divided into a plurality of air route sections, and a plurality of optimal stations of each air route section are acquired; the ADS-B broadcastsignals of an aircraft are received through the optimal stations, and a plurality of pieces of measurement information of the aircraft are obtained, wherein the measurement information at least comprises a time difference of arrival and an angle of arrival required by the aircraft; the aircraft is positioned according to the measurement information, and the first position information of the aircraft is obtained; and the first position information is compared with the second position information of the aircraft obtained according to the ADS-B broadcast signals, and prompt information is sent when an error between the first position information and the second position information exceeds a preset threshold. With the ADS-B broadcast signal-based airplane route monitoring method, the ADS-B broadcast signal-based airplane route monitoring device and the computer storage medium provided by the technical schemes of the invention adopted, positioning precision and robustness are improved, theproblem that ADS-B broadcast signals are easily tampered and attacked is effectively solved, and the reliability of air route positioning can be effectively guaranteed.

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...
