摘要
硬X射线调制望远镜(HXMT)卫星用于实现宽能区X射线高灵敏度和空间分辨率巡天成像。针对HXMT卫星载荷种类多、工作状态多样、卫星数据信息传递实时性和同步性要求高的特点,分析了卫星数据信息链的基本过程,设计了卫星数据信息链系统。通过采取冗余设计、容错设计等方式,保证了数据信息传递的实时性和可靠性。地面测试和在轨运行结果表明:HXMT卫星数据信息链系统运行稳定,满足卫星使用需求。
The HXMT(hard X-ray modulation telescope)satellite is used for wide band and wide field X-ray observation.In view of the characteristics of many kinds of loads,various working conditions and high real time and synchronicity requirements,the basic process of information chain is analyzed,and a Information chain system is designed.By using redundancy design and fault-tolerant design,the real-time and reliability of information chain is ensured.The application of information chain system is explained in matching test,and on orbit test results.
