Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a communication system. Background technique [0002] At present, the network communication of civil aviation aircraft during flight is mainly realized through the radio network transmission of satellites and ground base stations. This kind of implementation is limited by the radio frequency and the orbit position of geosynchronous satellites, and it is difficult to meet the rapid growth of mass data transmission in the civil aviation field. Requirements; and due to the performance limitation of the satellite radio communication network, the data transmission rate and the number of service users on the aircraft are limited. Although the Internet service in the cabin can be realized at present, the network communication rate is relatively low, basically in the order of KB and MB .

[0002] At present, the network communication of civil aviation aircraft during flight is mainly realized through the radio network transmission of satellites and ground base stations. This kind of implementation is limited by the radio frequency and the orbit position of geosynchronous satellites, and it is difficult to meet the rapid growth of mass data transmission in the civil aviation field. Requirements; and due to the performance limitation of the satellite radio communication network, the data transmission rate and the number of service users on the aircraft are limited. Although the Internet service in the cabin can be realized at present, the network communication rate is relatively low, basically in the order of KB and MB

[0003] Based on the above reasons, a large amount of flight data generated by the aircraft in the air cannot be transmitted to the ground in real time, making the aircraft an island of information in the air

With the development of aircraft intelligence, the data generated by intelligent aircraft equipped with thousands of sensors and complex digital systems has increased exponentially. If it is not effectively utilized, the control and maintenance costs of the aircraft cannot be reduced
