摘　　要：硬X射线调制望远镜(HXMT)卫星在轨长期连续观测、全天球任意姿态指向、观测目标频繁切换、观测载荷工作温度要求高等多任务、多约束的特点,使卫星的功能设计和传统卫星不同。为确保卫星好用、易用、安全、可靠,HXMT卫星从任务需求和特殊要求出发,以系统化、模块化的设计思路,遵循可交互性、可服务性、开放性的原则,设计了12种系统级在轨自主功能,其中9种为全新设计。卫星在轨运行结果表明:各项自主功能在轨应用效果良好,满足了用户对于卫星长期在轨运行高观测效率、高可靠、高自主、数据下传及时、使用简便灵活的需求。The HXMT(hard X-ray modulation telescope)satellite has the characteristics of multi-mission and multi-constraint,such as long-term continuous observation,arbitrary pointing in full-space,frequent switching of observation sources,high requirement of payloads working temperature control and so on,which make the system function design different from others traditional satellites.In order to ensure that satellite is convenient and easy to use,safe and reliable to operate in orbit,12 system-level autonomous functions are designed according to the mission requirements and special requirements with a systematic and modular design approach and the principles of interactivity,service and openness,of which 9 functions are entirely new design.The results of HXMT satellite operation show that the applications of autonomous functions are good,and HXMT satellite autonomous functions meet the needs of users for high observation efficiency,high reliability,high autonomy,timely data transmission,easy and flexible use in the long-term in-orbit operation of satellite.
