Abstract: In the problem of two spacecraft rendezvous, the multi impulse strategy can often achieve less fuel consumption. In this paper, the artificial bee colony algorithm is used to optimize the fixed time multi impulse rendezvous of spacecraft, and an improved artificial bee colony algorithm is proposed. This method can simplify the processing of time constraints and obtain solutions that meet the constraints of earth radius. This method is easy to program and robust, and can be applied to different perturbation models. Simulation results show that the algorithm is not easy to fall into local optima, and has higher accuracy than particle swarm optimization algorithm and traditional artificial bee colony algorithm.
