摘要
高分三号(GF-3)卫星具有大角度快速机动及复杂电磁环境的特点,测控分系统常规设计难以满足卫星需求。文章提出射频设备的抗干扰设计及验证方法,介绍了GF-3测控分系统的设计、技术特点,并给出了地面试验及在轨运行验证结果,实现了测控分系统高灵敏度接收与大功率合成孔径雷达(SAR)之间复杂环境的电磁兼容性,同时首次采用高精度实时快速导航定位算法和自主健康管理方法,实现了导航子系统快速连续定位。
GF-3 satellite has the characteristics of a large angle attitude maneuver and complex electromagnetic environment,conventional TT＆C subsystem design is difficult to meet the satel-lite design requirement.The design and verification method of anti-jamming of radio frequency equipment is presented.The design,technical characteristics,ground experiment and verification results of GF-3 TT＆C subsystem are introduced.The complex electromagnetic compatibility （EMC）between high sensitivity TT＆C subsystem and high power SAR system is realized.At the same time,it is the first time to using the real-time positioning algorithm and self-health manage-ment to achieve the navigation subsystem fast and continuous positioning.
