Embodiment Construction

[0044] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] The invention demonstrates the concept design of UNICON structure, laser communication payload, constellation configuration method, constellation range and communication spacecraft through sufficient research. For the first time, the design method of establishing a constellation network of 6 laser communication relay satellites on the heliocentric orbit between the earth orbit and the Mars orbit is proposed to solve the problem that the development of deep space exploration is limited due to the lack of a common ground measurement and control communication and tracking network. Seriously restrict the basic communication problems of countries, commercial companies and universities, etc., and provide general-purpose interstellar communication relay services for their deep space probes. It mainly includes the following aspects:

Abstract

The invention discloses a space-based deep space relay communication satellite networking system, the system includes: a spacecraft and a ground station, the spacecraft includes: UNICON heliocentric constellation and geosynchronous orbit constellation; the heliocentric constellation includes 6 UNICON communication satellites in heliocentric orbit through constellation layout, the geosynchronous orbit constellation includes 3 GEO satellites in geosynchronous orbit; user deep space probe transmits data to UNICON heliocentric constellation, and then through the earth The synchronous orbit constellation is sent to the ground station; two laser communication telescopes are set on the top of each UNICON communication satellite, and each laser communication telescope can rotate 180 degrees along the vertical axis to achieve 360-degree scanning, so that every two communication satellites Capable of laser communication. The satellite system of the present invention can provide high-speed data uplink and downlink access services for multiple deep space exploration tasks with 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...
