Deep space exploration communication system based on light quantum communication technology

Abstract

The invention provides a deep space exploration communication system based on light quantum communication technology. The deep space exploration communication system comprises a plurality of deep space probes, an earth track satellite and a ground station. The deep space probes are provided with quantum information sending sub-systems, the earth track satellite is provided with a quantum communication receiving station, and the quantum communication receiving station is respectively in communication connection with the quantum information sending sub-systems and the ground station. Quantum communication is conducted among the quantum information sending sub-systems and the quantum communication receiving station, and scientific probing data explored by the deep space probes is converted into light quantum signals to be sent to the quantum communication receiving station. The quantum communication receiving station receives the light quantum signals, conducts information decoding on the light quantum signals, and restores the light quantum signals into digital signals, and the digital signals are sent to the ground station through a radio frequency communication method. By means of the deep space exploration communication system, an energy consumption problem of a traditional classic communication scheme is solved fundamentally, and an effective method for building a high-speed broadband communication link for deep space exploration tasks is provided.

Description

technical field [0001] The invention relates to the technical field of deep space spacecraft communication, in particular to a deep space detection communication system based on optical quantum communication technology. Background technique [0002] With the implementation of my country's "Chang'e Project" and "Sino-Russian Joint Exploration of Mars Project" and other projects, my country's space technology, especially deep space exploration technology, has made great progress. It is expected that in the next 10 years, my country will develop and establish a deep space detection system with independent intellectual property rights, launch a series of deep space detectors, and carry out independent deep space detection research. This will greatly promote the development of my country's science and technology in basic physics, aerospace applications and astrophysical exploration. [0003] Deep space probes are far away from the earth. Traditional classical communication uses ...
