Communication system

Abstract

The invention discloses a communication system, and relates to the technical field of laser communication. The main purpose is to improve the rate of network transmission of an aircraft device. The main technical scheme is: the communication system comprises multiple satellites, each satellite carries an inter-satellite laser communication terminal device for performing inter-satellite communication, a satellite-aircraft laser communication terminal deice for the communication between a satellite and an aircraft device, and a satellite-ground station laser communication terminal device for realizing the communication between the satellite and a ground station; the multiple communication satellites are in a communication connection through laser links between the inter-satellite laser communication terminal device; the satellites perform inter-satellite data transmission though the established laser link, and the data transmission at least comprises data of the aircraft device receivedby the satellites and network resource data uploaded by the ground. The communication system is primarily used for aerial data transmission of aircrafts.

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 orbit satellites, and it is difficult to meet the rapid growth of mass data transmission in the civil aviation field. Demand; 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 orbit satellites, and it is difficult to meet the rapid growth of mass data transmission in the civil aviation field. Demand; 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, which further exacerbates the difficulty of downloading massive flight data in the air, resulting in flight data If it is not effectively utilized, it cannot reduce the cost of aircraft control and maintenance
