Earth-moon libration point constellation arrangement method

Abstract

The present invention relates to the field of aerospace technologies, and provides an earth-moon libration point constellation arrangement method, comprising: launching a plurality of satellites to a first zone by using a rocket, if the first zone corresponds to an earth-moon collinear libration point L1, sending the satellites to an L1 orbit to finish arrangement, removing the satellites from the first zone to a second zone, and then correspondingly sending the satellites to an L2 orbit and two earth-moon triangle libration point orbits to finish arrangement, and end the process, wherein both distances between the first zone and L1 and between the second zone and L2 are no greater than 50 thousand Km; and if the first zone corresponds to an earth-moon collinear libration point L2, sending the satellites to the L2 orbit to finish arrangement, removing a part of the satellites from the first zone to the second zone, then sending the satellites to the L1 orbit to finish arrangement, and sending the remaining satellites to the two earth-moon triangle libration point orbits from the first zone to finish arrangement, and end the process, wherein both distances between the first zone and L2 and between the second zone and L1 are no greater than 50 thousand Km. The present invention can reduce arrangement costs of earth-moon libration point constellation.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a method for laying out a constellation of earth-moon translation points. Background technique [0002] Since the space position of the Earth-Moon equilibration point is stable relative to the Earth and the Moon, if satellites are arranged on each Earth-Moon equilibration point to form a Earth-Moon equilibration point constellation, then the Earth-Moon equilibration point constellation and the common circumlunar constellation Compared with the following obvious advantages: [0003] 1) Taking the L2 translation point of the Earth and the Moon as an example, it is always visible relative to the back of the Moon, so that the number of satellites required for the same lunar coverage is small, the illumination time is long, and the apparent motion of the lunar user is slow and easy for antenna tracking, etc., if Deploying satellites at this translation point can directly provide r...

AI Technical Summary

Problems solved by technology

[0005] Based on the above analysis, how to deploy satellites on multiple Earth-Moon translation points has become an important research topic in this field. Of course, satellites at each translation point can be launched separately, but this will cause the deployment cost of the entire constellation to be very high. High, but there is no other method disclosed in the prior art that can realize the constellation layout of the Earth-Moon equilibration point
