国际电联亚轨道飞行器载电台国际标准化工作

International Standardization Studies of Stations on Board Sub-orbital Vehicles at International Telecommunication Union

针对国际电信联盟(International telecommunication union,ITU)在2015年世界无线电通信大会(World radiocommunication conference,WRC)上提出的关于亚轨道飞行器载电台无线电通信问题的研究,中国运载火箭技术研究院亚轨道飞行器研制团队协同国家无线电监测中心、北京跟踪与通信技术研究院积极跟踪参与电联工作,在WRC-19研究周期内完成了提交电联研究组讨论的亚轨道飞行器载电台通信技术报告,结合我国技术发展的实际需求,提出了满足全时通讯、大多普勒频移变化及克服通信黑障等的频谱需求策略。该议题是我国传统航天运载器无线电通信首次参与国际标准制定工作,对于我国的航天无线电通信需求在国际商业层面的合规使用提出了全新挑战。该议题将在2019年的WRC-19上提交大会审议,预期将在下一个WRC研究周期内继续进行业务需求和相应频谱需求的分析,以及后续的兼容性分析,从而为商业亚轨道在国际电联规则层面的合规使用做好技术支撑。

To conduct studies on Resolution 763(WRC-15)"Stations on board sub-orbital vehicles",a team from China academy of launch vehicle technology(CALT),along with state radio regulation of China and Beijing Institute of Tracking and Telecommunications Technology,participates in the cycle of WRC-19,and formulates technical report as"Radiocommunications for suborbital vehicles".Considering actual technical approaching of China’s suborbital vehicle modes,the team proposes possible spectrum criteria fulfilling the requirements of whole-period communication coverage,large Doppler shift and Doppler acceleration,and overcoming communication blackout.The agenda item is the first time for CALT to participate in international telecommunication standardization work,which brings new challenges for China’s aerospace radiocommunication requirements when commercializing at global level.This agenda item is discussed during WRC-19,anticipating for future further studies on radiocommunication regulatory,operations and services,technically ensuring stations on board suborbital vehicles shall be operated within the frameworks of ITU regulations.
