A STUDY ON LAUNCHING GEOSTATIONARY SATELLITE AT HIGH LATITUDE BY TAKEN ADVANTAGE OF THE MOON'S GRAVITATION

摘要: 提出了借助月球引力从高纬度地区发射地球静止卫星的方法.利用圆锥曲线拼接法对地球静止卫星的发射问题作初步分析,然后采用精确数学模型进行精确分析.研究表明,当发射场纬度大于28°时,采用借助月球引力的发射方法可以节省能量.发射场的纬度越高,节省得越多.Abstract: A method of make use of Lunar Gravitation (LG) to launch GeostationarySatellite (GS) at high latitude is preselited- At first, preliminary anaJysis of theproblem of launching GS is given using patchedconic technique. Then, preciseanalysis is given in a mathematical model. It is indicated that less energy is neededto launch GS from launch site with latitude higher than 28° using LG method thanthe traditional. The higher the launching site is, the more energy is saved.
