GEO卫星两种借力月球应急入轨转移轨道对比
Comparison of two methods for emergency orbit transfer using the lunar gravity assist for the GEO satellite
摘要
Abstract
In the condition of a partial launch success,the Geostationary Earth Orbit(GEO)satellite is able to transfer to the target orbit using its own maneuver with the assistance of lunar gravity.This method of orbit transfer enables emergency entry into orbit while conserving satellite fuel and extending its service life.The perilune window duration,the ability to alter the orbital inclination assisted by lunar gravity,fuel consumption during orbit transfer,the transfer duration,and other key parameters closely related to these two types of satellite maneuver control processes are systematically compared based on the high-precision ephemeris orbit dynamical model.The calculation results indicate that,compared to the method of swing-by from the rear of the moon,the method of swing-by from the front exhibits significantly shorter flight durations without any notable disadvantages in other key parameters.This finding provides valuable support for emergency orbit entry and control missions of GEO satellites.关键词
