Communication navigation monitoring system based on multi-mode data link

Abstract

The invention discloses a communication navigation monitoring system based on a multi-mode data link. The communication navigation monitoring system based on the multi-mode data link comprises an airborne system, a Beidou commanding terminal, an ADS-B (automatic dependent surveillance-broadcast) ground station, a ground MC (mobile communication) base station and a ground data processing center, wherein a GNSS (global navigation satellite system) module is used for collecting positioning information in the airborne system, and data interaction is carried out between the GNSS module and a ground Beidou sending and receiving terminal via a satellite link; an airborne ADS-B module is used for sending and receiving ADS-B information; an MC data link is established by an airborne MC module; an airborne data processing module is used for carrying out link judgment and switching; in the ground data processing center, a data link management and control module is in charge of link selection; the link information is firstly pre-processed by a receiving data pre-processing module and is then processed by a data fusion module to be stored into a target state database module. According to the communication navigation monitoring system based on the multi-mode data link, which is disclosed by the invention, the modular design is adopted, the communication navigation monitoring system has the expandability, data link judgment and switching can be carried out in real time, and therefore operation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of communication of general aviation aircraft in the field of general aviation, in particular to a communication, navigation and monitoring system based on multi-mode data links. Background technique [0002] With the continuous opening up of China's low-altitude field, general aviation, as an advanced production tool and technical means, is gradually becoming one of the two pillar industries of civil aviation. However, due to the relatively backward construction of general aviation in my country and the low level of support, especially the low-altitude surveillance service in a relatively large area, it is still difficult to meet the needs of the rapid development of general aviation. Therefore, how to provide surveillance means suitable for general aviation in low-altitude airspace is an urgent problem to be solved in the process of general aviation construction and development. [0003] General aviation ...

AI Technical Summary

Problems solved by technology

[0003] General aviation aircraft currently have a single VHF voice mode for communication and monitoring, and there is no effective means of operation monitoring. Compared with traditional transport aviation, general aviation has a more complex operating environment. Lack of means of communication, difficulties in ground surveillance, command and control, etc.
