Method and device for determining moon-earth transfer orbit

Abstract

The invention discloses a method and device for determining a moon-earth transfer orbit. The method comprises the steps of according to the approximate reentry time of a detector reentering a preset reentry point of the earth atmosphere from the moon, a preset orbit inclination angle when the detector arrives at the preset reentry point, the latitude and longitude of a drop point, and the moon-earth transfer time of the detector, determining a reentry time initial value of a preset reentry point; determining a moon-earth transfer orbit number of the preset reentry point, and determining a moon-earth transfer orbit under a two-body model according to the reentry time initial value and the moon-earth transfer orbit number; correcting the moon-earth transfer orbit under the two-body model to obtain a target moon-earth transfer orbit under the high-precision model; according to a preset intersection line strategy corresponding to a moon-earth transfer orbit and a moon-surrounding orbit, correcting a perilune height and a lunar section moon-earth transfer inclination angle in the target moon-earth transfer orbit under the high-precision model; and when the corrected lunar section moon-earth transfer inclination angle enables the perilune of the moon-earth transfer orbit to be in the lunar orbit plane, determining moon-earth incidence control parameters.

Description

technical field [0001] The present application relates to the field of aerospace technology, and in particular to a method and device for determining a lunar-earth transfer orbit. Background technique [0002] In the field of aerospace technology, the detection of extraterrestrial celestial bodies, such as sampling returns and manned moon landings, is of great significance to human activities. Correspondingly, the incident control of the return of the probe after sampling is a key step to the success of the mission, and this step is limited by the location of the return landing point, search and rescue and other conditions, and generally requires the probe to return and land at a fixed point. [0003] For manned missions to the moon or lunar sampling return missions, after completing the mission on the lunar surface and returning to the orbit around the moon through the ascent of the lunar surface, it is necessary to design a suitable moon-earth transfer orbit so that the pr...
