Embodiment 1
[0032] figure 1 A schematic flow chart of an air traffic control method provided in the embodiment of the present application, such as figure 1 As shown, this method includes:
[0033] The low earth orbit satellite system 101 is used to establish the first data link between the civil aircraft 104 and the air traffic control command 103;
[0034] A geosynchronous orbit satellite system 102, used to establish a second data link between the civil aircraft 104 and the air traffic controller 103;
[0035] The air traffic control commander 103 is configured to obtain the position information of the civil aircraft 104 through the first data link and / or the second data link, and perform information exchange with the civil aircraft 104 .
[0036] It should be noted that, generally speaking, the first data link established by the low-earth orbit satellite system can complete the purpose of air traffic control, but for the sake of safety and security, the second data link is establishe...
Embodiment 2
[0053] Based on the air traffic control system disclosed in the above-mentioned embodiments of the present invention, image 3 Specifically disclosed is an air traffic control method applied to the air traffic control system.
[0054] Such as image 3 As shown, the embodiment of the present invention discloses a kind of air traffic control method, and this method comprises:
[0055] S301. Establish the first data link between the civil aircraft and the air traffic control command through the low earth orbit satellite system;
[0056] S302, using the geosynchronous orbit satellite system to establish a second data link between the civil aircraft and the air traffic control command;
[0057] S303. The air traffic control command obtains the position information of the civil aircraft through the first data link and / or the second data link, and performs information exchange with the civil aircraft.
[0058] Optionally, the step S303, obtaining the position information of the ci...

Abstract
The invention relates to the technical field of data transmission, in particular to an air traffic control system and method, so as to solve the problems of inaccurate positioning and low information transmission efficiency caused by the use of a ground radar system in related technologies. The method comprises the following steps that an earth low-orbit satellite system is used for establishing a first data link between a civil aircraft and air traffic control command; the geosynchronous orbit satellite system is used for establishing a second data link between the civil aircraft and the air traffic control command; and the air traffic control command is used for acquiring the position information of the civil aircraft through the first data chain and / or the second data chain and carrying out information interaction with the civil aircraft. The data link between the civil aircraft and the air traffic control command is established through the earth low-orbit satellite system and the geosynchronous orbit satellite system, the updating frequency and the positioning precision of the position information of the civil aircraft are improved, and bidirectional real-time global voice communication between the air traffic control command and a pilot is realized.
Description
technical field [0001] The present application relates to the technical field of data transmission, in particular to an air traffic control system and method. Background technique [0002] Air control refers to the general term for the unified supervision, management and control implemented by a country on airspace or all flight activities in a certain airspace in peacetime or war. Also known as aviation control. The normal operation of civil aviation aircraft is inseparable from the air traffic control system. The change from procedural control to radar control has brought about a huge increase in air transport capacity. China's air traffic control currently implements a system of "unified control and separate command". Control, tower control, approach control and area control, China's airspace is roughly divided into 28 control areas, and each airport has a tower control area. [0003] At present, China's air traffic control uses the ground radar system to realize the ma...
