摘 要: | 随卫星上部署动态跟踪天线,难以进行卫星姿态控制,为此提出了一种采用两颗伴随卫星部署非跟踪天线的接收方案,用于接收低轨圆轨道星(LEO)到地球同步静止卫星(GEO)的上行信号。理论分析及STK(SatelliteToolKit)软件仿真结果表明,伴随星姿态只需在惯性空间内稳定,就可实现动态信号接收,大大降低了系统的实现难度。

Abstract: | Aiming at the difficulties in controlling the satellite's attitudes when installing tracking antenna on a companion satellite,A receiving method by double companion satellites with non-tracking antennas is designed to receiving uplink signals between LEO and GEO.Theoretical analysis and STK simulation result prove that the method is effective. |
