Space-based deep space relay communication satellite networking system

Abstract

The invention discloses a space-based deep space relay communication satellite networking system. The system comprises a spacecraft and a ground station, wherein the spacecraft comprises a UNICON heliocentric constellation and a geosynchronous orbit constellation; the heliocentric constellation comprises six UNICON communication satellites which are arranged on a heliocentric orbit through constellation layout, and the geosynchronous orbit constellation comprises three GEO satellites which are located on a geosynchronous orbit; a user deep space detector transmits data to the UNICON heliocentric constellation and then sends the data to the ground station through the geosynchronous orbit constellation; two laser communication telescopes are arranged at the top of each UNICON communication satellite, each laser communication telescope can rotate by 180 degrees along the longitudinal axis, so that 360-degree scanning is realized, and laser communication can be carried out between every two communication satellites. The satellite system can provide high-speed uplink and downlink data access services for deep space exploration tasks of different data rates and different orbits.

Description

technical field [0001] The invention relates to the field of laser communication relay satellite constellation networking, in particular to a space-based deep space relay communication satellite networking system, which is used to provide continuous communication relay services for interstellar missions between Venus orbits and Jupiter orbits. Background technique [0002] Since the first artificial satellite was launched on October 4, 1957, human beings have never stopped their curiosity to explore the entire solar system. So far, more than 150 probes have been sent into deep space to explore our solar system. Still, we've explored a tiny fraction of the solar system. At the same time, only traditional large countries and organizations (such as China, the United States, Russia, ESA, Japan, India, etc.) are capable of carrying out deep space projects. [0003] In recent years, there have been two new development directions for deep space exploration: [0004] The first de...

Problems solved by technology

With the gradual increase of the distance of deep space missions and the miniaturization of deep space probes, it is increasingly difficult for the existing ordinary tracking stations built for near-Earth missions to complete the tracking tasks of deep space probes
