西工大新闻网11月10日电  11月10日出版的《中国日报》(CHINA DAILY)上,以《Chinese CubeSats to participate in international study project》为题,专题报道了西工大微小卫星项目研究和团队情况。

《中国日报》是中国国家英文日报,创刊于1981年,全球期均发行90余万份,其中,海外发行60余万份。《中国日报》是国内外高端人士首选的中国英文媒体,是有效进入国际主流社会、国外媒体转载率最高的中国报纸之一。

该英文报道重点回顾了西工大参与欧盟QB50项目的进展情况,并对学校航天学院微小卫星团队建设和学术研究等情况,进行概要介绍。

近年来,学校微小卫星项目团队不断凝炼特色,整合资源,在学科建设、团队培育和国际合作等方面,都取得了重要突破。

2011年,欧盟启动了由比利时冯卡门流体动力学研究所、西北工业大学、荷兰代尔夫特理工大学、英国萨瑞大学空间中心等研究机构联合发起的QB50项目。QB50项目是欧盟第七框架协议项目,作为国际大科学计划,全球有30多个国家和地区超过1000名研究人员参与该项目。西北工业大学是该项目亚洲区唯一发起单位及全球三个任务控制中心之一,其余两个为美国斯坦福大学和比利时冯卡门流体力学研究所。

根据报道,“QB50”项目将通过发射微小卫星,组网对目前人类尚未深入涉足的低热层(90到300公里)进行研究,此外还将开展立方星编队飞行、太阳帆推进、太空垃圾清除、航天器再入返回等多项创新研究。

2016年4月24日,西北工业大学卫星地面测控站落成。该测控站与荷兰、韩国、泰国等国家的地面卫星测控站实现了联网,在微小卫星任务期间,可以通过不同地区分布的测控站对微小卫星状态进行监控,并实现信息共享。6月25日,西北工业大学研制的第一颗微小卫星“翱翔之星”,作为世界上首颗12U立方星,搭载“长征七号”新型运载火箭在海南文昌发射成功。该测控站即实现了与“翱翔之星”的“天地互连”。

同时,在创新创业教育方面,该团队也形成了颇具特色和市场前景的“未来规划”,并在2016年度全国众多“重量级”大赛上,连续创造佳绩,引起了社会公众、产业界和媒体的广泛关注。

9月,在第十八届中国科协年会全国科技工作者创新创业大赛上,西北工业大学的“太阳能Wi-Fi无人机”和“翱翔”系列微小卫星产业化两个项目摘得金奖。10月,第二届中国“互联网+”大学生创新创业大赛总决赛上,“翱翔系列微小卫星”项目从全国12万支团队脱颖而出,斩获冠军。

据悉,西工大“翱翔”系列微小卫星研制团队拥有雄厚的技术基础,目前已经形成2U、6U、12U等系列化的立方星及其组件产品,初步具备了年产10~20颗立方星的能力。团队负责人、西北工业大学陕西省微小卫星工程实验室主任周军教授曾表示,“该实验室在国内率先从事立方星研究,目前已经可以面向社会开放卫星定制服务,比如通讯定制、地图定制、空间实验定制等。”

该项目团队制定了立方星总体设计、系统集成和总装测试的研制规范,并提出基于“互联网+航天”的商业模式,提供面向团体和个人用户的低成本、模块化的功能定制卫星平台和定制 、个性化的空间信息服务等。

Chinese CubeSats to participate in international study project

Five Chinese-made microsatellites will be sent into space in the near future as part of a proposed international network of 50 satellites that will study the lower thermosphere, a layer of the Earth's atmosphere.

The QB50 project, an initiative by the Von Karman Institute in Brussels and funded by the European Commission, will simultaneously launch 50 CubeSats - microsatellites composed of cube-shaped units - on a single launch vehicle.

"The project has set records for the number of participant countries in international microsatellite projects and the number of satellites carried by a single rocket," said Zhou Jun, director of the Shaanxi Engineering laboratory for Microsatellites at Northwestern Polytechnical University in Xi'an, the capital of the northwestern province.

The CubeSats were produced by universities in more than 30 countries and regions.

Five Chinese universities - Northwestern Polytechnical University, the Harbin Institute of Technology, the National University of Defense Technology, Nanjing University of Science and Technology and Beihang University - have each provided a microsatellite for the project.

European countries have produced 19, while there are 10 from the United States, three from Japan and two from Canada.

"The satellite constellation will be sent into an orbit of 350 km and fall toward Earth from there. In the following three months, they will explore the thermosphere between 90 km and 320 km (above the Earth), about which we know little," Zhou said.

While most of the satellites will be double-unit CubeSats - composed of two units, each approximately the size of a 2 liter container - Zhou's team became so ambitious that it developed the world's first 12-unit CubeSat.

"Developing a 12-unit CubeSat is not as simple as piling up Lego bricks, so we had to redesign the satellite's structure and power system," said Huang He, an associate professor at Northwestern Polytechnical University.

In double-unit CubeSats, one unit provides the usual satellite functions while the other carries sensors for research. By contrast, the 12-unit CubeSat provides much more space for sensors.

In June, a Long March 7 rocket carried a 12-unit CubeSat into a 350-km-high orbit to test its structure, thermal control and power systems, communications and the direction of its axes.

"Our CubeSats use a wide range of off-the-shelf commercial components, so during the last launch we had to test the satellite's key technologies to ensure its dependability," Huang said.
