摘　　要：根据中继卫星的定点位置,对我国中继卫星-空间站的几何覆盖率进行了分析,并对提高空间站中继测控覆盖率的途径进行了研究,提出了一种采用不同舱段的2副中继天线融合使用,并通过调整天线安装布局提高中继测控覆盖率的方法。经理论分析和仿真验证,该方法能够有效地提高空间站中继测控覆盖率,可为我国空间站中继天线的安装布局设计提供参考。Considering the station position of the relay satellites, the geometrical coverage of the relay satellite for Chinese space station is analyzed. Furthermore, feasibility of improving the relay TT^C coverage is studied. Then, a method to improve TT^C coverage is derived by using multi relay antennas and placing them to proper locations. Finally, simulation results are presen- ted to demonstrate the accuracy and validity of the proposed method. This method can provide a reference for the design of antenna distribution for a space station.
