The solar ion thruster is applied to the propulsion system of the satellite to accomplish the task of transferring from the geostationary transfer orbit (GTO) to the geo-geosynchronous orbit (GEO). The mission model is established and the feedback control strategy based on the latitude and longitude angle is designed. The engine switching time The GA (Genetic Algorithm), which is accelerated by graphic processing unit (GPU), is used to optimize the design of satellite orbital mission.The simulation results show that by optimizing the steady-state parameters of the closed-loop controller, The orbit is guided near the target orbit and the solar ion thruster can reduce the fuel consumption.The genetic algorithm based on GPU acceleration can shorten the algorithm operation time.
