Research on the Optimization of Orbital Transfer Strategy Based on Improved Genetic Algorithm for On-Orbit Service Satellite

Abstract

On-orbit service technology aiming at maintaining and supplying orbit, prolonging orbit lifespan and cleaning orbital rubbish has great significance on reducing the cost of geostationary orbit satellite and making full use of stationary orbit resources. In order to solve the sequential planning problem of service satellite providing service for several target satellites, this paper proposed an optimal orbital transfer strategy of searching service satellite based on an improved genetic algorithm. It analyzed the orbital transfer process of service satellite, designed the individual coding mode and proposed an optimal operator to improve genetic nature. The simulation results showed that optimal orbital transfer strategy can be found according to the algorithm proposed in this paper. The strategy reduced much consumption in energy and time while the algorithm was fast in convergence and high in stability.
