Abstract

The invention discloses a ground station communication system, relates to the technical field of laser communication and mainly aims to achieve laser communication between the ground and a satellite.An aircraft communication system disclosed by the invention comprises at least one ground station laser communication terminal, wherein the ground station laser communication terminal communicates with the satellite; the ground station laser communication terminal comprises at least one ground station-satellite laser communication terminal device and communicates with the satellite through a laserlink based on the ground station-satellite laser communication terminal device; the ground station laser communication terminal further comprises a data communication interface and is connected witha public Internet network through the data interface. By adopting the system, communication can be carried out through the link between the ground station and the satellite, data of an aircraft in laser link connection with the satellite can be downloaded to the ground, and bidirectional communication of the aircraft with the ground can be achieved.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a ground station communication system in a laser communication network. Background technique [0002] At present, aeronautical communication is mainly realized through microwave satellites. When communicating through the microwave radio, since the radio frequency is the basis for normal communication between the aircraft and the satellite, and is the channel for information transmission, in order to prevent electromagnetic interference between satellites, it is necessary to maintain a certain interval of communication frequency for frequency isolation, so the radio Spectrum is strictly regulated by the International Telecommunications Union (ITU) and governments. In addition, radio communication has the problems of spectrum saturation and limited communication bandwidth, which makes it difficult to meet the high-speed transmission requirements of massive data, and it is even ...
