Abstract:An on-orbit reusable refueling policy and its mission scheduling for multiple geosynchronous satellites through a space fuel station is presented. In order to establish the scheduling model for the on-orbit refueling of multiple GEO satellites through a space fuel station

the relationship between the velocity change and the maneuver time for orbital transferring of service spacecraft is first obtained based on the analysis of the problem of two impulses orbital maneuver. A multi-objective optimization model for mission scheduling of on-orbit refueling for multiple GEO satellites is developed to optimize both the job sequence and job time distribution of the refueling mission

and a specifically design genetic algorithm is employed to search the solutions to this multi-objective optimization problem. To verify the effectiveness of the proposed scheduling algorithm

a computer simulation that aims at scheduling a mission of on-orbit refueling for 20 GEO satellites is conducted.
