Method research of satellite attacking path planning based on genetic algorithm

When the defense system of target satellite is made up of formation flying micro-satellites, the micro-satellites can maneuver to intercept incoming satellites. In order to approach target satellite, attacking satellite must find a security path to avoid interception by micro-satellites. In this paper, environment model for path planning was build on relative orbits model of micro-satellites. An optimizing method for attacking satellite path planning, based on genetic algorithm, was present by establishing comprehensive fitness function and designing genetic operator. Simulation results show that the proposed method can find an optimal path with good stability and convergence and the path can satisfy requirements of security and shortest route well.
