Problems solved by technology

However, the divergence angle of the laser beam is relatively narrow. Generally, a laser beam can only communicate with one other laser communication terminal; currently, a satellite is generally equipped with a laser communication terminal. To achieve the same time, the satellite is multiple laser communication terminals. services, which can only be achieved by launching multiple satellites, which is extremely costly

Abstract

The invention discloses an aircraft communication system, relates to the technical field of laser communication, and mainly aims to achieve laser communication between aircrafts and satellites. The aircraft communication system disclosed by the invention comprises at least one piece of aircraft-satellite laser communication terminal equipment, an electric control box, a rectification cover and a bracket, wherein the bracket has a damping function; the aircraft-satellite laser communication terminal equipment communicates with a satellite communication system through a laser link; the electriccontrol box is used for supplying power to the aircraft-satellite laser communication terminal equipment and used for providing control instructions to information streams; the rectification cover isof a structure which is transparent at least partially and is arranged on the outer side of the aircraft-satellite laser communication terminal equipment in a covering manner. The aircraft communication system is mainly applied to data transmission of aircrafts.

Description

Technical field [0001] The invention relates to the technical field of laser communication, in particular to an aircraft communication system in a laser communication network. Background technique [0002] At present, aeronautical communication is mainly realized through microwave satellites. When communicating through this microwave radio, since radio frequency is the basis for normal communication between aerospace vehicles and satellites, it is a channel for information transmission. In order to prevent electromagnetic interference between satellites, it is necessary to maintain a certain interval of communication frequencies for frequency isolation. The spectrum is strictly controlled by the International Telecommunications Union (ITU) and governments. In addition, radio communication has the problems of spectrum saturation and limited communication bandwidth. It is difficult to meet the high-speed transmission needs of massive data, and it is even more impossible to realize...
