Constellation layout and transmitting method of space-based deep space relay satellite

Abstract

The invention discloses a constellation layout of a space-based deep space relay satellite for deploying an interstellar communication relay constellation on a heliocentric orbit between the earth andthe Mars. The constellation layout comprises: the distance 1M from the relay satellite to the Mars is set to be equal to the distance 1E from the relay satellite to the earth, and meanwhile is less than a communication distance limit 1: lM = lE less than or equal to l. According to the method disclosed by the invention, the communication satellite is deployed on the heliocentric orbit between theearth orbit and the Mars orbit, so that hotspot deep space detection areas such as the Venus, the Mars, the asteroid belt, the Jupiter and the like can be covered, and the method has the advantages of wide coverage. In addition, the invention further discloses a transmitting method of the space-based deep space relay satellite. According to the method, a transmission mode of one rocket and doublesatellites is adopted, a satellite S1 and a satellite S2 are simultaneously transmitted by using the Long March 3B rocket, the fuel requirements of the satellites are completely consistent by means of the one-rocket-multiple-satellite transfer orbit design, so that batch design and manufacture can be achieved, and the transmitting method has the advantages of low cost.

Description

technical field [0001] The invention relates to the field of constellation networking of laser communication relay satellites, in particular to a constellation layout and launch method of space-based deep space relay satellites. 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 development direction is: more and more small and medium-sized countries plan to carry out deep space exploration proje...
