Design of circumlunar global positioning satellite constellation on DRO in the cislunar space
In order to achieve the design of a circumlunar global positioning satellite constellation,this article provides an overview of the current research on the lunar global positioning satellite constellation and conducts in-depth research on circumlunar constellation based on distant retrograde orbit(DRO).Firstly,taking the planar DRO of the circular restricted three-body model as the initial value,the three-dimensional DRO is described with the DRO's initial phase angle,orbital average period,and z-direction motion amplitude as parameters.The DRO that remains stable for three years in the bicircular restricted four-body model is calculated.Then,drawing inspiration from the concept of the Earth orbit Walker constellation,a circumlunar constellation design method based on the phase difference deployments such as DRO benchmark orbits is introduced.Finally,the performance of single-benchmark,double-benchmark,and quadruple-benchmark orbit constellations are analyzed for the DRO lunar constellation with 16 satellites in each constellation,and the effectiveness of the proposed DRO lunar constellation design method is validated.
