The invention relates to a moon global positioning constellation design method based on earth-moon space DRO reference orbits, and the method comprises the steps: determining the initial orbit state and orbit period of any DRO reference orbit based on the initial phase of any DRO reference orbit in to-be-deployed DRO reference orbits; and for any satellite to be deployed on the any DRO reference orbit, the initial phase of which is the target phase, determining the initial orbit state of the any satellite based on the orbit state corresponding to the target phase. And determining the orbital period of the any satellite based on the orbital period of the any DRO reference orbit. And obtaining a target orbit state corresponding to the any satellite based on the orbit period of the any satellite and the initial orbit state of the any satellite. And constructing a lunar global positioning constellation under the four-body model based on the target orbit state corresponding to each satellite. Compared with the existing near-moon constellation, the lunar global positioning constellation constructed by the invention has higher stability and higher lunar surface coverage capability.
本发明涉及一种基于地月空间DRO基准轨道月球全球定位星座设计方法,基于待部署的DRO基准轨道中的任一DRO基准轨道初始相位,确定该任一DRO基准轨道的初始轨道状态和轨道周期。对于待部署在该任一DRO基准轨道上初始相位为目标相位的任一卫星,基于目标相位对应的轨道状态,确定该任一卫星的初始轨道状态。基于该任一DRO基准轨道的轨道周期,确定该任一卫星的轨道周期。基于该任一卫星的轨道周期和该任一卫星的初始轨道状态,得到该任一卫星对应的目标轨道状态。基于每一颗卫星对应的目标轨道状态,构建在四体模型下的月球全球定位星座。本发明构建的月球全球定位星座与现有的近月星座相比具有较高的稳定性和较高的月表覆盖能力。
