  • The key point of guaranteeing the distributed satellites system performance is to design the formation of the satellites appropriately. This paper studies the satellite formation optimization of distributed satellites system which moves on flying around orbit, and presents a new optimization method based on height-measure error. A composite pixel height error model after combining the multiple baseline measurements is presented, and the height error of the given scene is presented. Finally, the height error model of given scene is used to optimize the satellite formation of distributed satellites system by using genetic algorithm. The simulation results show that this method can decrease the height error of the given scene.
