Optimal Scheduling of GEO On-orbit Refuelling with Uncertain Object Satellites

Autor: Yu Jing, Yu Yong-gang, Huang Jiang-tao, Chen Xiao-qian, Liu Hong-yang

Publikováno v: MATEC Web of Conferences, Vol 114, p 03001 (2017)

The mission planning of Geostationary Earth Orbit (GEO) on-orbit refuelling with uncertain object satellites is studied in this paper. Three key problems should be resolved here: Object Satellite (OSc) selection, mission sequence planning and transfe
