摘要
由于火箭发射入轨精度的限制 ,无法直接发射形成星座 ,星座的形成需要变轨。该文针对三星星座 ,进行星座发射中的最优脉冲式变轨研究。文中基于卫星相对运动状态转移方程 ,推出了星座双脉冲式变轨控制的理论解 ;利用遗传算法 ,对双脉冲式变轨的脉冲控制量进行了优化仿真 ;探讨了星座脉冲式变轨的工程实现途径 。
In studying and developing constellation technology, constellation launch is one key technology. When launching constellation, because of the limit of rocket launching accuracy, satellites can not be launched with rocket to make constellation, orbit transfer is necessary. In this paper, thinking of three-satellite constellation, optimal impulse orbit transfer is studied for constellation launching. In the paper, based on relative motion equation of satellite state transferring, analytic solution of two-impulse orbit transfer of constellation is derived, by means of genetic Algorithm, control variables of two-impulse orbit transfer are optimized, and engineering method of impulse orbit transfer of constellation is discussed.
