Communication system

Abstract

The invention discloses a communication system, relates to the technical field of aviation and spaceflight, and mainly aims to increase the network transmission rate of an aircraft. The main technicalscheme is as follows: the communication system comprises a satellite communication system and an aircraft communication system; the satellite communication system comprises multiple satellites; eachsatellite carries an inter-satellite laser communication terminal device for inter-satellite communication, a to-air laser communication terminal device for communication between the satellite and theaircraft, and a to-ground laser communication terminal device for communication between the satellite and a ground station; the multiple communication satellites are in communication connection through a laser link based on the inter-satellite laser communication terminal device; and the aircraft communication system comprises a predetermined number of aircraft-satellite laser communication terminal devices for communication with the satellite, and performs communication connection with the satellite communication system through the laser link based on the aircraft-satellite laser communication terminal devices. The communication system disclosed by the invention is mainly used for air data transmission of the aircraft.

Description

technical field [0001] The invention relates to the technical field of laser communication, 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 wireless network transmission of satellites and ground base stations. This implementation method is limited by the wireless frequency and satellite orbit, and its use in the civil aviation field is limited; and wireless network data transmission Due to the limitation of spectrum bandwidth, the data transmission rate and quantity on the aircraft are limited. Although the Internet service in the cabin can be realized, the network service can only be a slow and expensive network service. [0003] With the full liberalization of the use of smart mobile terminals during aircraft flight, how to provide fast and low-cost network services for users using smart mobile terminals on aircraft has become an urgent probl...
