Abstract:

Aiming at the problem of multi-Satlet layout plan in the process of the reuse of the retired satellite’s large scale antenna, the multi-Satlet antenna dynamics equation is derived based on Lagrange equations. By analyzing the effect of the antenna vibration on location of Satlet layout and the vibration effect of Satleton antenna system,the antenna system’s Satlet layout planning constraints are proposed. And then, the genetic algorithm is used to optimize Satlet layout positionin multi-antenna system, and the optimal location of Satlet in antenna system is given. Then the covariance matrix adaptation evolutionary strategy (CMAES) is used to validate the accuracy of optimal Satlet position given by the genetic algorithm. The numerical simulation is proposed at last and is used to demonstrate that the retired spacecraft antenna’s attitude control project is valid in the reuse process when the optimal Satlet position is accepted in the retired spacecraft system.
