小卫星布阵让全球上网无盲区
2017-08-30 06:21:27 中国青年网
本报讯(记者贺亮)8月29日,记者从第三届中国(国际)商业航天高峰论坛新闻发布会上获悉,中国航天科工集团将在汉打造“虹云工程”,让全球互联网“盲区”不再有,实现互联网的全球覆盖。
由于沙漠、山脉和海洋等环境因素,世界上还有一半的人口没有接入互联网,信息的匮乏限制了当地经济文化的发展,“虹云工程”着力解决这一问题,以天基互联网接入为主要目标,基于低轨通信星座及其地面系统,与现有通信系统相辅相成,为“互联网+”战略的实施和产业化发展搭建信息交互平台。
这也正是“虹云工程”一个亮点所在,它在中国首次提出建立基于小卫星的低轨宽带互联网接入系统,“小卫星”“低轨”“宽带”的组合设置也正契合商业发展的需求。
按照规划,整个“虹云工程”实施三步走战略。第一步计划在2018年前,发射第一颗技术验证星,实现单星关键技术验证;第二步到“十三五”末,发射4颗业务试验星,组建一个小星座,让用户进行初步业务体验;第三步到“十四五”末,实现全部156颗卫星组网运行,完成业务星座构建。
“虹云工程”具备通信、导航和遥感一体化、全球覆盖、系统自主可控的特点,以其极低的通信延时、极高的频率复用率、真正的全球覆盖,可满足中国及国际互联网欠发达地区、规模化用户单元同时共享宽带接入互联网的需求,促进网络互通互联,促进国民经济建设和文化交流,创造可观的经济价值和社会价值。同时,也可满足应急通信、传感器数据采集以及工业物联网、无人化设备远程遥控等对信息交互实时性要求较高的应用需求。
据悉,“虹云工程”将作为重点项目入驻位于武汉新洲区的国家航天产业基地。
