针对主从式GEO星群系统星间测控需求，研究了该星群系统最简模型和工作模式，提出了一种地球同步轨道主从式星群的星间测控系统设计方案。该方案阐明了主星（及从星）星间测控链路的具体设计和系统关键技术环节的实现方式，资源占用少、工程实现性强、链路可靠性高。对方案设计结果进行分析后表明，在配置1主星和2从星的最简模型中，主星仅通过一套星间测控链路便可完成与2从星的星间测控任务，较以往频分实现模式有源设备配置减少50%、功耗减少近50%；通过全向天线形成的星间测控覆盖域，确保了链路的可靠可用，可以满足用户需求。
For the InterSatellite TC&R demand of GEO MasterSlave Satellite Group, proposed a design after the research on its minimalist model and working mode. The program clarified the specific design and key technology of the InterSatellite TC&R Link with features of Low consumption, easy engineered and reliable. Analysis of the design result shows that master can fulfill the ISL TC&R task with 2 slaves in only one ISL TC&R channel, enabling the achievement that 50% reduction of active device configuration and nearly 50% reduction of power consumption compared with traditional FrequencyDivision mode. The interSatellite TC&R coverage produced by Omnidirectional antenna ensured the reliability and stability of the link, which better met the user’s need.
