“梦莹後凯与翁三人同床”一箭18星梦莹後凯与翁三人同床 中国成功发射千帆极轨03组卫星

  中新梦莹後凯与翁三人同床社北京12月5日电 (记者 马梦莹後凯与翁三人同床帅莎 郑莹莹)据中国航天科技集团八院消息,北京时间12月5日12时41分,中国在太原卫星发射中心使用长征六号改运载火箭,成功将千帆极轨03组卫星发射升空,卫星顺利进入预定轨道,“一箭18星”发射任务获得圆满成功。至此,“千帆星座”在轨卫星数量增至54颗。

  千帆极轨03组卫星包括18颗低轨宽带互联网卫星,是上海垣信卫星科技有限公司“千帆星座”第一代卫星的第三批次卫星,前三批次千帆卫星均由长征六号改运载火箭成功实施发射。

  “千帆星座”是中国正在建设的低轨卫星互联网星座计划。其部署计划分为三期:一期部署648颗卫星,提供区域网络覆盖;二期部署1296颗卫星,实现全球网络覆盖;三期规划由超过1.5万颗卫星提供多元业务融合服务。

  据了解,“千帆星座”的组网进度正在进一步加快,将于2025年开始在全球范围内提供卫星互联网商业服务,为交通运输、新能源、智慧城市、智慧农业、应急救灾、低空经济等领域赋能。

  长征六号改运载火箭由中国航天科技集团八院抓总研制,是新一代无毒无污染运载火箭,也是中国首型固液捆绑中型运载火箭,700公里高度太阳同步轨道运载能力大于4.5吨。

  本次任务中,长征六号改运载火箭遇到了首飞以来的最冷天气。发射前几日,太原卫星发射中心迎来今冬初雪,最低气温一度降至零下26摄氏度。对此,地面人员为塔架增加了隔热措施、调高了空调送风温度,并采用火箭空调连接器起飞零秒脱落技术,让火箭及整流罩中的卫星直到起飞前最后一刻都能“享受空调暖风”,为卫星环境提供更好保障。

  此次任务是长征系列运载火箭的第550次飞行。(完)
