摘　　要：针对中继卫星应用于航空飞行器类目标的跟踪,研究了中继卫星跟踪航空器的星间天线指向控制问题。在考虑中继卫星捕获跟踪系统工作特点和航空器飞行特点的基础上,完成了基于航空器预定航迹的中继卫星星间天线跟踪指向控制算法,通过采用分段拟合方法和有约束的最小二乘算法,实现了航空器跟踪弧段内星间天线稳定的高精度指向控制。进行了航空器某预定航迹的跟踪控制计算,仿真算例表明了该指向控制算法的有效性。Aiming at the tracking and data relay satellite(TDRS) tracking target of the aircraft,the inner orbit linked antenna(IOLA) pointing control algorithm for TDRS tracking the aircraft was studied.Considering the characteristics of TDRS acquisition and tracking system and the flight of the aircraft,the pointing control algorithm of IOLA tracking the aircraft based on the prearranged path was completed.The high precise pointing movement of IOLA was executed with the control strategy using the multisection fit method and least square method with restrictions.The example of tracking control calculation was done and the control algorithm showed its high precision.
